The Louis Vuitton Foundation and ist Design under Turbulent Wind
Authors: Leroy Amaury , de Ville de Goyet Vincent
Published: February 2021

The Louis Vuitton Foundation in Paris is a building drawn by the well‐known architect Franck Ghery. As it can be observed on the above pictures, the structure is very complex and its behavior was not easy to deal with. If the dead load had to be analyzed with precision, the wind loading was another challenge. Of course, tests in a wind tunnel lab were carried out in order to measure the net wind pressures on the twelve glass roofs, wind pressures that had to be used for the design.For each roof, the design office had the distribution of the pressures for different wind directions related to time. For the design, the PSD of the wind measures on each sensor were at the disposal of the engineers. First difficulty, the maximum frequency of the lab measurements was about 1 Hz whereas the first frequency of the roofs was about 2 Hz. Second difficulty, as far as the design was concerned: it was essential to extract some equivalent wind loadings for each roof with the aim that these loadings were representative of maximum induced wind effects.For that purpose, a mathlab program has been developed to conduct a spectral analysis based on a finite element model of each roof. The paper will describe the procedure and the main equivalent wind loading used for the final design of the structure.
Reliability of Structures that Pass Imperfect Proof Load Tests
Authors: Bartlett F. Michael
Published: February 2021

Proof load tests have the potential to confirm the structural safety of a component suspected of being substandard. Methodologies are available to revise the reliability index of the suspect component, after it passes a proof load test, that essentially assume that the probability that the actual resistance is less than the proof load is zero. There is some sense among practitioners, however, that “you can always pass a proof load test” and so the current methodologies for updating the reliability index may be unconservative.

This paper presents the development of rational criteria for including proof load testing into the safety assessment that account for imperfect repeatability of the test result. The necessary mathematical formulation requires the following steps:

Define the likelihood that a particular proof load test can be successfully repeated, i.e., (100-α)%;

Partially truncate the lower tail of the resistance distribution such that the cumulative probability corresponding to the load test magnitude equals the probability that the load test will not be successfully repeated, i.e., α%; and,

Carry out reliability analyses using the partially truncated resistance distribution.

Preliminary findings are presented assuming the load and original resistance distributions are normal. Two example calculations demonstrate the applicability of the method, and indicate ist potential value in determining the necessary test load magnitude to achieve a desired reliability index.
Reliability-Based Site-Specific Live Load Models for the Gordie Howe International Bridge
Authors: Ude Todd , He Y. Eddie , Chynoweth Matt , Yousif Zaher
Published: February 2021

This paper discusses the development of project-specific live load models to achieve target reliability levels for the Gordie Howe International Bridge. This new bridge between Windsor, Ontario Canada and Detroit, Michigan USA will have a main span of 853 m (2800 ft), a design life of 125 years, and will experience atypical traffic patterns as a result of customs inspection plazas required at both ends of the bridge. Due to these variations relative to standard practice, large databases of weigh-in-motion data and simulation studies were used to modify the live load models of both country’s codes following the approach of NCHRP 683. The limit states addressed extend beyond the Strength 1 (ULS 1), to include high dead-to-live ratio combinations, and fatigue limit states.
Design for Future Transit Rail Maximizes Benefits from Initial Investment for the Gov. Mario M. Cuomo Bridge
Authors: Wright Kenneth J. , Vasiljevic Milos P. , Vineyard Preston D.
Published: February 2021

The new Governor Mario M. Cuomo Bridge spans the Hudson River between Rockland and Westchester
Counties in southern New York. A key design criterion was to accommodate various modes of transportation
in the future. This paper discusses how the bridges will accommodate dedicated bus rapid transit lanes as
well as the potential future construction of a transit bridge between the structures without installing
additional foundations in the river. The transit bridge would require significant rail construction on either side
of the river to provide viable connections to existing rail lines, making it prohibitively expensive. The transit
bridge will fit between the two highway bridges and carry two rail lines. We will explain how the highway
bridges will accommodate the future rail bridge without providing needless excess capacity into the piers and
foundations built under this design-build contract.
Ecological mass timber as an answer to affordable housing in Switzerland?
Authors: Gaudry Laurent , Chabloz Martial , Golchan Darius , Nembrini Julien , Schmid Matthias
Published: February 2021

The lightness and thermal performances of timber has led designers to consider using it for urban densification and to make it the key for a more sustainable and affordable construction industry.

This project of a timber-framed high-rise building will become one of the tallest in Switzerland to adopt a wooden construction, using a mix of two types of manufactured wood: cross-laminated timber (CLT) for structural walls and glue-laminated timber (a.k.a. glulam) combined to an upper concrete layer linked with screws for the slabs. The use of timber sourced from local forest is considered by the engineers because its abundance in Switzerland.

The concrete layer is needed to reach a high level of acoustic performance and to efficiently create horizontal diaphragms for earthquake resistance. It also enables the reduction of the thickness of the complex. The lower wooden surfaces with warm natural appearance are visible from the rooms, as well as the vertical surfaces of the CLT wall supporting them.

The project reveals the complexity for timber structures to simultaneously comply with regulations concerning structural, fire safety, acoustical and earthquake-resistance performances. Building Information Modeling (BIM) allows excellent technical installations coordination to reach a high degree of prefabrication.

Authors: Cobas Ana C. , Cichero Renso A. , Tortoriello Miguel A. , Lima Luis J.
Published: February 2021

The development of timber constructions all around the world may be a very important component in a global policy of affordable housing. To realize this target timber constructions must have adequate security and acceptable durability. It means to have a well-founded Specific Structural Theory and sufficient data about deterioration process and rheological comportment. In this paper we analyze: a) the advantages and disadvantages of timber constructions; b) the main basic hypothesis to develop a theory concerning the “Strength of Wood Material Bodies” (a specific Strength of Materials referred to timber constructions); c) a more precise method to determine wood strength in any case; d) an adequate policy to assure desirable durability of timber constructions.
Mass Timber: Looking Back to Effectively Look Forward
Authors: Oppenheimer Nat
Published: February 2021

The use of mass timber as a structural element is not a new phenomenon. For example, within almost every major city in the world, there are upscale enclaves centered around the adaptive reuse of factories and warehouses from the late 19th and early 20th centuries. These former industrial structures are almost always constructed from masonry and mass timber.

Within the past decade, the building industry has seen a renewed interest in mass timber structures. This resurgence has been fueled by several trends, including the mass production of Cross Laminated Timber (CLT) and a growing awareness of mass timber’s sustainable advantages. A number of high-profile heavy timber structures have found commercial success in the United States and abroad. Leading architectural practices such as Skidmore Owings & Merrill (SOM) have used research initiatives like the Timber Tower Research Project to jump-start a fertile debate within the design industry. On the demand side, building owners have pushed the design community to find innovative ways to incorporate mass timber into their projects.

This interest has often driven designers and builders to aggressively distinguish their projects from predecessors, pushing for pure mass timber structures while giving less consideration to hybrid structures (mass timber and masonry/concrete structures). This bias towards material purity risks ignoring important lessons from the past and may in some cases lead to inefficient structural choices and structures with less durability and sustainability than their hypothetical hybrid counterparts.

This paper posits that some of the energy generated by a resurgence in mass timber construction would be well spent on understanding, celebrating, and rediscovering the elegance and importance of hybrid structures.
Tall Mass Timber Present and Future – 2 Case Studies
Authors: Peronto John , Komp Jordan , Fernandez Alejandro
Published: February 2021

According to the 2018 UN Global Status Report, “buildings construction and operations accounted for 36% of global final energy use and nearly 40% of energy-related carbon dioxide (CO2) emissions in 2017”. [1] In a society leaning towards sustainable practices and efficiency, the improved structural properties of mass timber compared to traditional wood construction present a unique opportunity to add a sustainable material to the designer’s palette. This paper will focus on three subject areas:

Current code challenges and developments related to the IBC

Ascent, a 21-story mass timber tower currently underway in Milwaukee, WI. Upon completion, Ascent would be the tallest timber building in the Western Hemisphere. In addition to discussing the structural engineering principals behind the tower design, the team will elaborate on the current challenges associated with a project of this magnitude.

River Beech, a research project centered on an 80-story all timber tower that pushes the limits of mass timber construction to pinpoint technical challenges that require future research. River Beech incorporates a high level of prefabrication and modularization, and utilizes a high degree of automation common to the mass timber construction fabrication process.

The authors, based on their experience during the design of the case studies referenced above, will present an innovative technology capable of addressing the urban challenges related to building in a 21st century metropolis, while incorporating a sustainable and accessible material.
Failure Prediction Model for 3-Ply CLT Panels
Authors: Schultz Joshua A. , Hickman Seth
Published: February 2021

Mass production of cross-laminated timber (CLT) lends itself to cost efficient and sustainable building solutions and is an effective solution for affordable residential housing. Currently, most panel research focuses on longer span, thicker (i.e., 5-, 7-, 9-ply) panels. However, 3-ply panels are important both for residential construction and as a post-fire strength model for 5-ply. As a first step in developing a failure prediction model, 15 three-ply V2 CLT specimens were tested using four-point bending and characterized by ultimate strength, stiffness and shear utilization for comparison to PRG 320 values. The shear and flexure utilization were 350% and 615%, respectively, indicating significant residual strength beyond allowable design values. Results were analyzed to examine correlation between ultimate strength and material defects, suggesting that the ultimate strength of the V2 CLT tested was governed by the shear strength of the middle (perpendicular) layer and that flaws within lumber grades did not noticeably impact the ultimate stresses for the aspect ratios considered.

Ultimate failure loads were used to develop a failure prediction model. The minimum required out of plane third point load for probability of failure (POF) of 1:1000 is 17.1kN. The loads associated with a 50:1000 and 100:1000 POF are 24.1kN and 31.3kN, respectively. The POF curve was best-fit to obtain a design equation.
Beam tests for a wireless modal-based bridge monitoring system
Authors: Kohm Mareike , Stempniewski Lothar
Published: February 2021

Many bridge superstructures, with internal bonded pre-stressing systems, are in a critical state-of-health, due to enormously increased traffic loads. They can no longer comply with the requirements of today’s and tomorrow’s traffic. Therefore, intensive monitoring is required to ensure timely detection and localization of damages in the structure.

In this paper, we present our experiment results on a method to timely detect bridge damages. We analyzed the influence of beam damage and crack formation on the modal parameter’s natural frequencies and mode shapes. In our lab experiment, we introduced vibrations into concrete beams, measuring them with MEMS acceleration sensors. The progressive crack formation was measured by the classical use of a crack lineal and with the optical measurement system ARAMIS by GOM GmbH [1]. We were able to successfully measure a frequency drop at a crack width significantly below the serviceability limit state (SLS), showing the partial applicability of the presented method. As we were unable to measure the expected change of the mode shapes with sufficient accuracy, we suspected an unprecise time synchronization of our sensors. By performing numerical simulations, we were able to show that synchronization has no impact on the natural frequencies. However, synchronization has a significant impact on the quality and accuracy of the mode shapes.
Study on improvement of strength of Beam-column Joints at railway RC rigid-framed viaducts
Authors: Kunii Michihiro , Tsukishima Daisuke , Kuraoka Mareki
Published: February 2021

In Japan, in order to make the city centering around the station, we are developing the underpass of the station as a commercial facility. Therefore, a structure that enlarges the column span and reduces the cross-sectional height of the beam to widen the under-elevated space is desired. However, while the amount of reinforcing bars increases, the beam-column joints become smaller, so that the reinforcing bars are overcrowded in the beam column joints. In addition, since the fixing length of the reinforcing bars is insufficient, or the strength of the beam-column joint cannot be sufficiently secured, problems such as not having a sufficient proof stress on the joint portion which should originally be stronger than the beam and column member. In this report, we developed a fixing method of reinforcing bars of column beams which improves the proof strength of beam-column joint and also simple reinforcing bars even in the case of small beam-column joint, and applied to station construction work, we report on them.
Assessing the durability and residual carrying capacity of a prestressed footbridge built in Brussels (Belgium) in 1944
Authors: Espion Bernard , Provost Michel
Published: February 2021

In October 1944, a 20.9m span footbridge was built in Brussels (Belgium) across the Canal Charleroi-Brussels: it was the first applications of prestressing by post-tensioning to a concrete bridge-type structure in Belgium, and one of the earliest worldwide. The tendons consisted of high strength steel wires 5mm in diameter anchored in so-called « Sandwich » anchorages, a system of post-tensioning developed in Belgium from 1942 onwards by Professor Gustave Magnel with the Blaton-Aubert Company. This system will be extensively used in Belgium during the next 20 years, and was also applied to build the first prestressed concrete bridge in the US in 1949 (Walnut Lane, Philadelphia). The dead weight of the footbridge is 60 tons. Some years ago, the local Authority had decided that this footbridge had to be replaced. This 1944 prestressed concrete footbridge was obviously an engineering heritage structure, but preserving it in use somewhere else raised many problems in terms of reliability. The authors therefore proposed to the Authority to study in depth this historical structure in order to collect information that could be useful to assess the durability and actual carrying capacity of concrete structures built with the same prestressing technology in the period 1945-1965, many of them still standing. The paper presents the main findings from the load testing of this footbridge, that took place in October 2018, and the results from the characterization of its materials.

A Study of the Translation of English Legal Vocabulary under the Guidance of the Skopos Theory
Authors: Qian Chunxu
Published: February 2021

With the rapid development of society, most of countries around the world are all attaching importance to the construction of the rule of law. Many countries are drawing lessons from each others’ excellent legal achievements. Legal translation is an important branch of translation field and is playing an increasingly essential part in legal changes. With the deepening of China’s rule of law, China’s construction of legal system has stepped into a new phase. A large number of excellent Chinese legal documents are being translated into English, and many laws of Britain and America also have been translated into Chinese. The globalization of law has been an irreversible tendency. With the vigorous development of legal translation, how to correctly translate foreign legal achievements into Chinese has become a very arduous task for translators. The research field of legal translation includes the study of vocabulary, discourse, sentence and so on. The quality of translation of English legal vocabulary is key to deciding the quality of the whole translation of the legal text. Guided by the Skopos theory, which is a well-known theory put forward by German School of translation, the author makes a preliminary study on the translation of English legal vocabulary. By using and analyzing example sentences, the author makes summary about five characteristics of English legal vocabulary: common English vocabulary expressing legal meanings, use of ancient English vocabulary, parallel use of synonyms, use of modal verbs, use of professional terms and legal jargon. On the premise of conforming to the Skopos theory, four strategies of translating English legal vocabulary are summarized by the author according to these characteristics of English legal vocabulary, which are respectively fuzzy processing of English legal vocabulary, giving play to translators’ subjectivity, possessing consciousness of legal texts, correct use of domestication and foreignization. The author stresses the important role of translators’ subjectivity in the translation of English legal vocabulary, the correct use of domestication and foreignization and lastly links characteristics of English legal vocabulary, the Skopos theory and strategies of translation of English legal vocabulary effectively. The study has the certain innovation and reference significance in improving the quality of legal translation.
