Cold-formed Steel-Concrete Composite Beams with Back-to-Back Channel Sections in Bending
Authors: Rajić Andrea , Lukačević Ivan , Skejić Davor , Ungureanu Viorel 
Published: November 2023

Steel-concrete composite structures are very attractive because of their characteristics, which can be emphasised by using cold-formed steel instead of hot-rolled ones. This paper presents possible analytical approaches and a parametric finite element study of cold-formed steel-concrete composite beams in bending. Analysed beams are formed of back-to-back cold-formed steel channels and concrete slabs connected by demountable shear connectors. A solid concrete slab on a profiled metal sheet analysed. Also, the study investigates the influence of corrugated web between the back-to-back channels of different thicknesses. In the case of a corrugated web, the distance between the shear connectors is increased. Furthermore, different degrees of shear connection, shear connector quality, and their arrangements are considered. An analytical study is based on full and partial shear connection assumptions and non-linear bending resistance. It is shown that the steel channel thickness and degree of shear connection significantly influence the beam bending capacity as well as concrete slab configurations. Conversely, a discrete connection between steel elements has a minor effect. A comparison of the maximum obtained bending capacities in FE analyses is in good agreement with analytical approaches for full and partial shear connections.

A Mathematical Approach for Predicting Sufficient Separation Gap between Adjacent Buildings to Avoid Earthquake-Induced Pounding
Authors: Jaradat Yazan , Far Harry , Mortazavi Mina 
Published: November 2023

Studies on earthquake-related damage underscore that buildings are vulnerable to significant harm or even collapse during moderate to strong ground motions. Of particular concern is seismic-induced pounding, observed in numerous past and recent earthquakes, often resulting from inadequate separation gaps between neighboring structures. This study conducted an experimental and numerical investigation to develop a mathematical equation to calculate a sufficient separation gap in order to avoid the collision between adjacent mid-rise steel-frame buildings during seismic excitation. In this study, the coupled configuration of 15-storey & 10-storey, 15-storey & 5-storey, and 10-storey & 5-storey steel frame structures was considered in the investigation. The investigation concluded with a large number of data outputs. The outputs were used to predict structural behavior during earthquakes. The obtained data were categorized into three main categories according to the earthquake's Peak Ground Acceleration (PGA) levels. Also, the derived equations were divided into three different equations to estimate the required seismic gap between neighboring buildings accordingly. The derived equations are distilled to empower engineers to rigorously evaluate non-irregular mid-rise steel frame buildings. Doi: 10.28991/CEJ-2023-09-10-02 Full Text: PDF
Shear Performance of Reinforced Concrete T Beams Strengthened by Carbon Fiber-Reinforced Polymer Bars
Authors: Alhilli Hussain Hassan , Al-Farttoosi Mahdi H. 
Published: November 2023

The primary purpose of this work is to investigate the shear response of T-reinforced concrete beams strengthened for shear using the embedded through section (ETS) technique when subjected to a monotonic one-point load till failure. The experimental approach included an examination of the twelve reinforced concrete T-beams, including two reference beams without any strengthening and ten strengthened beams. The twelve beams were divided into two main groups, with and without stirrups. The main variables in every group were the spacing and angle of inclination of the carbon fibre-reinforced polymer (CFRP) bars. The beams were strengthened in shear with CFRP bars inserted in the centre line of the section with different spacings and angles of inclination. The experimental analysis was performed to study the effect of spacing and angle of inclination of the CFRP bars on the ultimate load capacity, load-strain relationships, and load-deflection relationships. Results showed that the ultimate load of the beams in group one with inclined CFRP bars (45°) increased by 29.7, 22.4, and 15.5% for beams with CFRP bar spacings of 10, 15, and 20 cm, respectively, compared with the reference beam. In group one (with stirrups), the beam with inclined CFRP bars (45°) and a spacing of 10 cm has an ultimate load higher than that with vertical CFRP bars (90°) with a similar spacing by 2.6%. By contrast, the beam with inclined CFRP bars (45°) and a spacing of 10 cm in group two (without stirrups) has an ultimate load higher than that with vertical CFRP bars (90°) with a similar spacing by 2.5%.

Modeling of Heat Transfer in Massive Concrete Foundations Using 3D-FDM
Authors: Mansour Dina M. , Ebid Ahmed M. 
Published: November 2023

Analyzing and modeling the thermal behavior of mass concrete elements has been widely investigated by several researchers. Lately, many contemporary finite element packages have embedded modules for analyzing thermal behavior. Unfortunately, these packages are quite complex and require experts to be properly implemented. This paper proposes a simple and practical approach using the 3D-Finite Difference Model (3D-FDM) developed by MS-Excel to overcome the complexity of the other FE models. The model is utilized to predict the thermal behavior of actual bridge pile caps (3D model) rather than the previously developed 2D models in earlier research. The results of the analysis are compared with the concrete temperatures that were experimentally obtained from the site. Site data was collected using 18 thermocouple probes (K type) that were installed in two pile caps. These thermocouples were installed before concrete pouring to monitor the temperatures generated due to the exothermic reaction of the cement, which occurs during casting and the maturity period of concrete. The readings were registered every 3 hours for 7 days after concrete placement. This research provides a comparison between the recorded site data and the thermal analysis based on the proposed 3D-FDM. Results proved that concrete temperature time histories at different locations of the bridge pile caps could be properly predicted using the developed 3D-FDM.

Published: November 2023

Kanji adalah salah satu huruf yang dipakai oleh masyarakat jepang dalam kehidupan sehari-hari. Asal-usul kanji digolongkan dalam teori bernama rikusho. Dalam rikusho penggolongan kanji dibagi menjadi shokei-moji (象形文字), shiji-moji (指示文字), kaii-moji (会意文字), keisei-moji (形声文字), tenchuu-moji (転注文字), dan kasha-moji (仮借文字). Salah satu unsur yang mempengaruhi bentuk kanji adalah bushu. Bushu memiliki peranan penting terhadap makna kanji karena masyarakat Jepang juga menggolongkan kanji berdasarkan bushu yang dimiliki kanji tersebut. Salah satu bushu yang menarik adalah nikudzuki (月), karena bushu tersebut memiliki bentuk yang mirip dengan kanji tsuki (月) yang berarti “Bulan”, akan tetapi bushu nikudzuki malah tidak berhubungan dengan “Bulan” melainkan berhubugnan dengan “Daging”. Dalam penelitian ini akan mengklasifikasikan kanji yang memiliki bushu nikudzuki yang terdapat pada kamus kanji Tadashikukakeru Tadashikutsukaeru Chuugakukanji 1130 dalam rikusho. Peneitian ini menggunakan naritachi untuk mengetahui asal-usul pembentukan kanji. Dan menggunakan metode deskriptif sebagai desain penelitan dan kualitatif sebagai pendekatan. Dua puluh sembilan data yang ada di dalam penelitian diklasifikasikan ke dalam 3 rikusho. Dua belas data termasuk dalam klasifikasi kaii-moji (会意文字). Lima belas data termasuk dalam klasifikasi keisei-moji (形声文字). Dua data termasuk dalam klasifikasi tenchuu-moji (転注文字).

Authors: Vedhathiri Thanikachalam 
Published: November 2023

In this fast-growing world, the need for engineers and technologies improves rapidly. Institutional development is possible only when we recruit outstanding faculty members but they need continuous development to effectively contribute to the human and knowledge capital. Many researchers focused on a few aspects of faculty development. Hence, this research focused on the planned development of the faculty from recruitment to retirement. An empirical model entitled “RODEORR” has been developed with the contribution of 306 faculty members from one state. The model consists of the following seven focused factors: 1. Recruitment based on faculty’s excellence, intrinsic and achievement motivation, 2. Orientation of the newly recruited faculty members to the goals, vision, mission, and objectives of the institute, 3. Continuous focused development of the faculty members based on equity, ethics, integrity, and excellence through in-house faculty development, sponsored global faculty development, and mass open online courses, and allowing self-determined development programs, 4. Continuous evaluation of faculty performances, accomplishments, and innovations, 5. Utilizing the opportunities for growth of the faculty members, 6. Rewards and recognition for the faculty members' outstanding performances and contributions to society, and 7. Assisting safe retirement by paying the pension and other accrued finances. If the outstanding faculty members desire to contribute to the development of knowledge capital, they can be reemployed as per the Education Ministry’s guidelines. The suggestions have been validated through a set of four principals and they accepted the continuous faculty development.
