Developments of Concrete-Filled Steel Tube Structures Stiffened by Diagonal Ribs
Xuhong Zhou, Dan Gan, Zheng Zhou, Yongjian Liu, Zexiang Li, Hongpeng Li
2024, 39(1): 1-28. doi: 10.13206/j.gjgS23071102
Abstract:
Concrete-filled steel tubular (CFST) columns have high strength, favorable seismic performance, reasonable cost, and are widely used as the main structural types in high-rise buildings and heavily-loaded structures. In comparison to circular CFST col...

Finite Element Analysis of Seismic Performance of Concrete-Filled Square Steel Tubular Column to Composite Beam Joint with Stiffening Ring Under High Axial Pressure
Faxing Ding, Luyu She, Linli Duan, Jianxiong Lei
2024, 39(1): 29-40. doi: 10.13206/j.gjgS23072801
Abstract:
Concrete-filled steel tubular column to composite beam joint with stiffening ring is widely used in super high-rise buildings due to its excellent performance. This paper conducted finite element research on the seismic performance of concrete-filled...
Research on Interface Sliding Behavior and Seismic Performance of Stirrup-Confined Concrete Filled Circular Steel Tubular Columns Under High Axial Compression Ratio
Changbin Liao, Faxing Ding, Yicen Liu, En Wang, Liping Wang, Liangliang Zhang, Yinan Deng
2024, 39(1): 41-52. doi: 10.13206/j.gjgS23083101
Abstract:
Normal concrete filled steel tube columns (CFST) exhibit poor potency under high axial compression ratio in seismic action. In contrast to other inner constraint measures of CFST, the transverse stirrups effectively prompt the constraint confinement ...
Comparative Study on Seismic Performance of Several Types of Square Section Piers at the Same Cost
Biao Li, Fei Lyu, Hao Sun, Faxing Ding, Yongqiang Cai, Chaocheng Zhang
2024, 39(1): 53-67. doi: 10.13206/j.gjgS23063003
Abstract:
The seismic performance of the traditional reinforced concrete pier is insufficient under strong earthquakes, but the concrete filled steel tube (CFST) pier has better seismic performance. CFST pier has broad application prospects in highway, express...
Design Discussion
Confining Effect of Square Tube to Filled Concrete and Welds Between Walls
Genshu Tong
2024, 39(1): 68-70. doi: 10.3724/j.gjgS23082020
Abstract:
The distribution of confining stresses and bending moments along 4 side-plates in concrete filled tube as a compression member are introduced. The plastic hinge lines formed in side-plates in the ultimate states are assumed and the average confining ...
