Experimental Investigation of a Fan-Shaped Assembled Joint for Curved Lattice Shells
XU Jianshe, WU Jin, LU Jin, ZHANG Qian
2022, 37(12): 1-9. doi: 10.13206/j.gjgS22081402
Abstract:
A new fan-shaped assembled joint for curved lattice shell structure is proposed, which is mainly composed of three parts: fan-shaped component, central rib plates and high-strength bolts. Different from the traditional welded joints, the main section...
Section Optimization of Elastic-Plastic Buckling of Cold-Formed Thin-Walled Lipped Channel Steel Column Based on Machine Learning
QUAN Song, HUANG Lihua
2022, 37(12): 10-17. doi: 10.13206/j.gjgS22032502
Abstract:
There are many factors that affect the elastic-plastic buckling capacity of cold-formed thin-wall steel lipped channel members. However, the relationship between section form and bearing capacity cannot be accurately expressed analytically. In order ...
3D Laser Scanning Technology Research for Erection Line-Shape Monitoring of Long-Span Steel Truss Arch Bridge
AN Luming, ZHAO Jian, REN Yanlong, SHI Linze, CHENG Bin
2022, 37(12): 18-23. doi: 10.13206/j.gjgS22051001
Abstract:
The rapid development of bridge construction level leads to the increasing demand for bridge construction volume and construction risk dynamic assessment. Line-shape monitoring is crucial in the erection process of large steel truss arch bridge, whic...

2022, 37(12): 31-36. doi: 10.13206/j.gjgS22041801
Abstract:
The roof structure of the middle group project of Xiaohe International Convention and Exhibition Center is the most complex part. It belongs to the discontinuous long-span orthogonal inclined space tube truss structure. It is divided into three parts...
Key Technology of Cross Steel Truss Construction of Supercomputer Cloud Roof
YANG Guosong, ZOU Huanmiao, CUI Qiang
2022, 37(12): 37-44. doi: 10.13206/j.gjgS22032301
Abstract:
The structure of the Xiongan Supercomputer cloud project is novel in shape, and the spatial relationship is complex. The floor under the roof is split-level, so it is difficult to choose the installation plan and support layout. Therefore, it is nece...

Distortional Buckling of Framed Beams: Stiffener or Fly Bracing?
TONG Genshu
2022, 37(12): 45-47. doi: 10.13206/j.gjgS22101206
Abstract:
The concepts ”independent bracing” and “ relative bracing” were explained, fly bracing between bottom flanges of orthogonal framed beams was a type of relative bracing whose functions were played only when the other beam had surplus stiffness and cap...
