EXPERIMENTAL STUDY ON MECHANIC BEHAVIORS OF CONCRETE-FILLED STEEL TUBULAR are ARCH UNDER IN PLANE LOADS

Chen Bao-chu

Abstract

In this paper, two model experiments of the concrete-filled steel tubular (CFST) rib arch under in-plane loads are reported.It is found that CFST rib arch has good elastic-plastic behavior and high strength. The mechanic behavior Of CFST rib arch under in-plane load is studied. The simplified methods to calculate the structure's in-plane ultimate strength are discussed as well.
