Stability Capcity of Circular Steel Tube Beam-Columns Under Uniaxial Bendings
Lei Xu, Genshu Tong
2021, 36(9): 1-9. doi: 10.13206/j.gjgS20111601
Abstract:
In the current Standard for Design of Steel Structures(GB 50017-2017), the clause 8.2.4 is specifically devoted to the buckling strength of beam-columns with circular pipe cross-section, but the only difference from the clause 8.2.1 for the beam-colu...
Finite Element Simulation and Parametric Analysis of Composite Shear Walls with Steel Plates and Infill Concrete Under Axial Compression
Jing Li, Wucai Lu
2021, 36(9): 10-18. doi: 10.13206/j.gjgS20062202
Abstract:
The previous researches on composite shear walls with steel plates and infill concrete mainly focused on their seismic performance, but few researches on their axial compressive performance and stud stress characteristics. Also, the influences of som...
Stress Analysis of Ultra-Wide Orthotropic Steel Box Girder with Large Width-Span Ratio and Single Inclined Pylon
Zhichao Shang, Li Chen, Fan Chen, Tingyu Li, Yong Tian
2021, 36(9): 19-24. doi: 10.13206/j.gjgS21012602
Abstract:
Geometrical asymmetry in cable-stayed bridges with single pylon leads to differences in stresses and deformation in comparison to conventional ones. Thin-walled orthotropic steel girder with big width/span ratio has more complicated loading and defor...

Measurement Method of Initial Geometric Deflections of T-Section Steel Struts
Xiaoli Xiong, Meng Ma, Kun Du
2021, 36(9): 25-32. doi: 10.13206/j.gjgS20032402
Abstract:
Initial geometric deflection is one of the important factors impacting on the overall stability bearing capacity of steel struts. The common initial geometric deflections of the steel strut with T-section include the initial bending deformation of th...
Study on Reinforcement of Steel Truss Bridge Based on External Prestressed Load Lifting
Hao Ding, Rui Li, Jing Mo, Xiaozhang Li, Di Liu
2021, 36(9): 33-39. doi: 10.13206/j.gjgS21041601
Abstract:
The concept of in vitro prestressing originated from France at the earliest and is one of the important branches of post-tensioning prestressing system, which usually adopts large-diameter steel bars, steel strands and high-strength steel wires as te...

Design of Members for Torsion
Lijun Wang
2021, 36(9): 40-48. doi: 10.13206/j.gjgS20081802
Abstract:
Design methods of torsion member in AISC 360-16 are introduced. Only closed sections are included for the torsion calculation in AISC 360-16. Pure torsion is considered mainly in torsion calculation with consideration for helpful factors of constrain...
