Review
Research Progress on Mechanical Properties of Concrete-Filled Steel Tube Members Under Corrosive Environment
Qingqing Xiong, Jiahui Qian, Zhihua Chen
2022, 37(7): 1-19. doi: 10.13206/j.gjgs22041501
Abstract:
Concrete filled steel tubes(CFST) are easy to fall off the rust layer in the process of transportation and construction, and they are in service under the action of corrosive gas, liquid and soil, which further aggravates the corrosion of steel tube ...
Research
Evaluation of the Mechanism and Influence Parameters of the Core Concrete Debonding in the Concrete-Filled Steel Tube
Yue Chen, Gang Wang, Xiaobin Hao, Guihai Yan
2022, 37(7): 20-30. doi: 10.13206/j.gjgS21110501
Abstract:
The concrete-filled steel tube(CFST) combines the structural and mechanical properties of both steel pipe and concrete and are widely used in high-rise buildings as well as bridge structures. Over time, the steel pipe and the core concrete will defor...
Approximating Formulas for Out-of-Plane Stiffness of Flange Plates in Inner-Outer Flanges
Yong Guo, Wending Mou, Yong Chen, Cheng Chen, Yujia Mei
2022, 37(7): 31-40. doi: 10.13206/j.gjgs21122001
Abstract:
The inner-outer flange(IO flange) is a high-capacity connection for circular hollow section(CHS) tubes, and is mainly implemented in long-span tubular transmission towers for the connection of the high-strength members. The axial tension capacity of ...

Research on Integral Lifting of Floating Truss Structure Based on Ring Hoop Reinforcement System
Chuang Zhao, Wenyan Zhao, Zuosheng Cao, Changgang Liu
2022, 37(7): 41-51. doi: 10.13206/j.gjgS22021001
Abstract:
The floating office project of Hunan Radio and Television Station is a large plane multi-layer truss structure supported by multiple tubes. At present, the conventional in-situ construction scheme for the structural system requires a huge amount of m...
Design Discussion
Shear Mechanism and Shear Capacity of Anchor Bolts
Genshu Tong
2022, 37(7): 52-54. doi: 10.13206/j.gjgS2022080501
Abstract:
Mechanism of tension development in anchor bolts when they are in shear is described. Three stages of action are detected when the bolts are in shear. A formula for shear capacity used in design and a formula for ultimate shear capacity are proposed.
