Flexural Strength Calculation of Concrete Filled Steel Tubular (CFST) Composite Truss Bridge

摘要

A simplified calculation approach for the flexural strength of CFST composite truss bridges was presented based on the pin-jointed analysis. The failure modes prediction and flexural strength calculation can be achieved by comparing the efficient factors of different bridge components. The approach can take the joint resistance into consideration and greatly simplify the design process of the CFST truss bridges.
