Abstract: The shear strength of composite circular concrete-filled steel tube (CFST) and reinforced concrete–filled steel tube (RCFST) structural members was investigated using finite-element analysis and existing test data. Results ...

Abstract: A single enlarged shaft foundation is often used to support bridge columns. In some conditions, it is constructed with a permanent steel casing, which is typically ignored in calculating the structural resistance of the ...

Abstract: The cyclic-shear behavior of composite circular concrete-filled steel tubes (CFSTs) and reinforced concrete-filled steel tubes (RCFSTs) was experimentally and numerically investigated. Specimens with 32.39 and 40.64 cm ...
