ANALYSIS OF THE PLASTIC MECHANISM ON COMPOSITE STEEL FRAME (WEAK AXIS OF COLUMN) WITH PR CONNECTION—REINFORCED CONCRETE INFILL WALL STRUCTURAL SYSTEM

Based on the observations of SRCW structure system, referring to the experimental failure modes of specimens in reference 1, the plastic mechanism was built. According to the principle of energy, the iteration method was adopted to analyze the ultimate load of the structure, the specimens in reference 1 were taken as an example to examine the accuracy of calculated results, and the accuracy of the proposed method is verified.
