Abstract:In order to study the mechanical behavior and the failure mode of existing RC frame structure, a real three-story RC frame structure including external masonry walls was tested by lateral loading. The global structure exhibited a column-sway collapse mechanism with shear-flexure hinges at the top ends of the columns at the first story. The external wall along the loading direction at the bottom story exceeded its ultimate capacity indicated by a large through-the-wall diagonal crack. A Local-Fine Model (LFM) i… Show more
