Carbon fiber reinforced polymer (CFRP) has the characteristics of high-strength and good corrosion resistance. Encased I-shaped CFRP profile into concrete-filled square steel tubular structure (CFRP-CFSST) forming a new-typed composite member can not...
Finite Element Analysis of Pure Bending Properties of Square Steel Tube-Wood-Concrete Members
Yan Gao Guochang Li Xiao Li
2024, 39(7): 38-46. doi: 10.13206/j.gjgS23110202
Abstract:
Wood is widely used in engineering because of its high load-bearing capacity, green and renewable. In order to reduce the amount of concrete in steel pipe concrete members, and reduce structural weight, the wood is placed in the steel pipe concrete, ...
Axial Compression Performance of Slender Concrete-Filled Circular Steel Tubular Column with Pitting Corrosion Damage
Jianwei Li, Lanlan Wang, Chen Jia, Lanhui Guo
2024, 39(7): 47-54. doi: 10.13206/j.gjgS23111502
Abstract:
Localized pitting corrosion damage can cause an adverse impact on the safety of concrete-filled steel tubes (CFST). This paper conducted a numerical analysis of the axial compression performance of slender CFST with pitting corrosion damage. The fail...
