Abstract

Abstract

Unequal thickness walled rectangular concrete-filled steel tubes(CFT) are a sort of optimization design for rectangular CFT as beams.It is derived a theoretic formula for calculating the ultimate strength of unequal-thickness walled rectangular CFT members subjected to pure bending based on relevant theoretical assumptions.the correctness of the theoretical formula is demonstrated by the degenerated analysis.The results obtained by the formula agree well with those of the experiments.Which are in the permitted scope of projects.
- unequal-thickness wall,
- rectangular concrete-filled steel tube,
- pure bending,
- bearing capacity
