Authors: Lv Zhengyu , Shi Jianyong , Chen Peizhi 
Published: April 2021

Abstract
Because of the high complexity and large scale of transmission line engineering, a large amount of data will be generated in the traditional two-dimensional (2D) design process, and the work of each stage is relatively independent. The design results are difficult to be effectively managed and integrated, and timely information interaction within and between specialties can not be achieved. BIM (Building Information Modelling) technology has powerful functions of digitalization and information management. This paper studies the application of BIM technology in three-dimensional (3D) design of overhead transmission lines. With the help of Revit platform and secondary development technology, combined with “Xinfu 110 kV transmission and transformation” project, a standardized family library of overhead transmission lines is established, and a set of algorithms for automatic sorting of insulator strings and automatic generation of overhead lines are developed, which realizes the parametric design of the lines in 3D environment. The whole process is centered on BIM information model database, which solves the problem of information management and interaction in traditional 2D design, and improves the design efficiency and quality.

Published: April 2021

Abstract
In this paper, three test models were cast about the grid -tube- type double steel plate and infilled concrete composite shear wall, the horizontal low cyclic loading test was carried out, and hysteresis curves and skeleton curves were got under different coaxial compression ratios. The results show that the new composite shear wall has many advantages, such as full hysteresis curve, high bearing capacity, high ductility and high energy dissipation capacity. Under the large displacement angle of 1/25 and cyclic loading of 80 times, the plastic hinge area still maintains the large stiffness and bearing capacity, which can effectively prevent the collapse of the structure under the action of a major earthquake. New composite shear wall has good seismic performance, which can realize the design requirements of high axial compression ratio, high ductility and thin thickness walls.

Authors: Gao Qinglin , Yin Fuxin 
Published: April 2021

Abstract
Eccentrically braced frame (EBF) incorporates the advantages of lateral resisting systems from moment resisting frame (MRF) and concentrically braced frame (CBF) into a single structural system. In order to investigate the effects of brace and link length in resisting progressive collapse, a finite element model of 10-story planar steel frame were built and analyzed with the SAP2000 software through nonlinear static analysis and nonlinear dynamic analysis respectively. The results show that brace can obviously improve the performance of the structure no matter which kind of brace is adopted. The inverted V-shaped (IV) eccentrically braced frame has the highest capacity against progressive collapse and the Y-shaped eccentrically braced frame has the highest energy absorption capacity of the structure. Increasing the link length leads to an increase in deformation and energy absorption of the structure. The results of nonlinear static analysis could reflect the structural performance basically.

Abstract
In order to better study the corrosion of rebar inside reinforced concrete, the corrosion position of rebar inside concrete is judged. Put rusted rebar, no rusted rebar, mixed rebar (rust and non-rust) on one side of the concrete test piece, and mark the position of the rebar, use the four-polarization method to observe the resistivity and polarity of reinforced concrete, and study the concrete interior. The degree of corrosion of rebar, the corresponding relationship between the position change and its polarization rate, the results show that: the longer the age of concrete, the worse the conductivity of concrete, the polarization rate of rusted rebar is greater than the polarization rate of un rusted rebar, when rebar is pre-buried above concrete, The polarization rate measured by concrete is greater than that of reinforced pre-buried under concrete. The polarization rate of pre-buried rusted reinforced concrete, the polarization rate of pre-buried mixed rebar, and the polarization rate of pre-buried non-rusted reinforced concrete. It is shown that pre-buried rusted reinforced concrete is more likely to produce polarization effects. The results show that it is feasible to judge the degree of corrosion of steel bars inside concrete by using the four-polarization method.

Published: April 2021

AbstractConventional First order reliability method (FORM) usually encounters divergence and non-convergence for high nonlinear performance functions. This paper puts forward an improved FORM coupling with a newly raised metaheuristic optimization algorithm, that is, Group teaching optimization algorithm (GTO). The GTO algorithm is inspired by grouping teaching strategy, featured by no additional control parameters, and has shown excellent global search ability for high nonlinear problems. Thus, the GTO algorithm is utilized to solve the equivalent constrained optimization problem according to the first order reliability theory. The implementation procedure of the proposed method is then presented in this paper. A numerical example is employed to verify the performance of the proposed method. Traditional reliability methods and PSO-based FORM are also introduced to compared with the proposed approach. The simulation results prove that the proposed method provides good performance in terms of computational efficiency and accuracy.

Authors: Yao Jinhui 
Published: April 2021

Abstract
The composite air supply for tall space buildings has always grabbed the researchers’ attention. Tall and square-built spaces generally have more complex building structures, along with challenges such as high system energy consumption, poor sewage disposal efficiency, and difficulty in heat dissipation. In addition, tall and square-built space buildings will have a greater impact on the flow of indoor airflow with respect to the air inlet/outlet selection, layout position, and spray angle. Therefore, in order to choose a more suitable plan and create a more reasonable airflow organization form, we use CFD numerical simulation method to simulate the airflow organization of a tall and open-duplex-structured factory in mainland, China. By setting different air supply parameters and air supplier column parameters, the composite air supply scheme combining the tuyere type and the air supplier column type is evaluated respectively. The experimental results show the feasibility and innovation of this scheme to increase the exhaust air volume, reduce energy consumption, and improve the heating effect in tall and square-built space buildings, and also provide a stereotype for the future application of examples on air distribution in similar buildings.

Abstract
The durability of coastal reinforcement suffers serious threaten by the aggressive chloride in marine environment. The repairment of structures under service or new construction design has become an important part with increasing the requirement of long service lives of infrastructure, while the applied repairment should be inconsistence with the corrosion condition of different concrete structure in the port. Herein, this paper comparatively discusses the various deterioration level of pile, beam and slab under the same marine environment, and provide the guiding principles for further repairment. The results show that the beam structure exhibits the worst performance among three typical reinforcement structures. The exposed rebars of beam structures are seriously corroded due to the chloride attack and result in low corrosion potential and serious concrete spalling. In contract, the slab structure exhibit better durability with intact appearance, low chloride penetration and high corrosion potential.

Published: April 2021

Abstract
The new fabricated box-shaped steel grid-concrete composite thin-shell roof structure is a new structure based on the large-span steel-concrete composite thin-shell roof. An assembly unit composed of thin-walled steel ribs with bolt holes, a steel bottom plate, and concrete, and a thin-shell roof structure formed by assembly connection between the assembly units. A comparative analysis of the deformation and stress of the flat roof and arched roof structure shows that when the span is less than 30m, the difference between the deformation and stress of the two structures is not large, and it is more reasonable to choose the flat assembled composite roof structure. The construction difficulty is lower. When the span is 40m, the maximum vertical displacement of flat roof and arched roof are 53.73mm and 17.81mm respectively, and the difference gradually increases from 40m. After the span exceeds 40m, the stress between the steel box and concrete of the flat roof structure. The ratio increases sharply, and the arched roof shows a uniform change trend. The material utilization rate of the arched roof is higher than that of the flat roof.

Published: April 2021

Abstract
Experiments were conducted on seventy-two stone panels to investigate the connection strength of undercut anchorage stone cladding. The following factors were considered in this study: the stone type, the distance between the hole center and the edge of the plate, the hole depth and the diameter and type of the undercut anchor. The results show that the stone type and anchor depth are the factors that most strongly influence the anchorage strength. The distance between the hole center and the edge of the plate are secondary factors. The connection strength increases when the distance between the hole center and the edge of the plate from 40 mm to 60 mm. The anchorage strength of percussion anchor is approximately 10% higher than that of a screw-in anchor under the same conditions.

Published: April 2021

Abstract
A double steel plates composite shear wall member composed of “L” elements (D-L-SCW) was proposed in this paper and its seismic behavior was preliminarily studied. With the shear-span ratio as test parameter, two specimens with actual ratio of 0.5 were constructed and tested in horizontal low-cycle reverse loading test. The failure modes, hysteretic behavior, skeleton curve, ductility and energy dissipation of the specimens were studied. Results showed that the suggested composite shear wall has significant seismic performance and can make more full use of the properties of both materials. The shear-span ratio mainly affected the peak load of the specimens, whilst it didn’t affect the overall deformation trend.
Research on Reinforcement Technology of Grid Bars with Oversized Slenderness Ratio
Authors: Wang Yong , Hu Ziwei , Dong Xu 
Published: April 2021

Abstract
The stiffness of axially loaded members is usually measured by slenderness ratio, which is the ratio of the calculated length of the member to the minimum turning radius of the member section. If the slenderness ratio is too large, the component is easy to produce bending deformation in the process of use. Under the action of dynamic load, it will produce large amplitude vibration, and it is easy to produce bending deformation in the process of transportation and installation. Therefore, the slenderness ratio of the component should be controlled in the design to make it not exceed the allowable slenderness ratio specified in the specification. Aiming at the problem that the slenderness ratio of space truss exceeds the limit, this paper puts forward the method of reducing the calculated length of members by adding supporting members or auxiliary members, so as to reduce the slenderness ratio of members, and studies the influence of increasing supporting members on the bearing capacity, deformation and seismic performance of space truss, so as to provide theoretical basis and guidance for the implementation of the reinforcement method.
