In consideration of the requirements for "normal use", the Aseismic Technical Guidelines Based on Maintaining the Normal Use Function of Buildings (RISN-TG046—2023) incorporates control requirements for "floor horizontal acceleration" by incorporatin...
Discussion on Shape Coefficients of Wind Loadings for Glass Curtain Walls of Twisted High-Rise Structures
Jingjing Dong
2025, 40(1): 42-51. doi: 10.13206/j.gjgS24070801
Abstract:
In recent years, an increasing number of super high-rise structures have adopted more complex cross-sectional forms (such as variable cross-section, chamfered cross-section, cross-section torsion, etc.) to meet the requirements of aesthetic and iconi...
Numerical Research on Shape Coefficients of Wind Loads of Industrial Buildings with Overhanging Awnings
Yijun Xie, Hua Xia, Zhengfeng Shen, Linlang Tong, Wei Li, Hongyu Pan
2025, 40(1): 52-57. doi: 10.13206/j.gjgS23090801
Abstract:
Long-span light-gauge steel industrial buildings are typical wind-induced sensitive structures, which are prone to wind-induced disasters. The wind load is closely related to the shape of the building. Due to functional requirements,long cantilevered...
Analysis of Welding Residual Stresses and Prediction of Delayed Crack Initiation Location in Flat Butt Welds
Aizhu Zhu, Manhui Zhang, An Liu
2025, 40(1): 58-67. doi: 10.13206/j.gjgS23122602
Abstract:
Delayed cracks are particularly difficult to detect and can be highly hazardous. Their location is often difficult to predict, and if not identified in a timely manner, the cracks may expand during bridge operation, which usually leads to brittle fra...
