Risk Analysis of High-Rise Reinforced Concrete Frame-Shear Wall Structure in Progressive Collapse

Abstract:

The purpose of the this study was to find the influence of local members of high-rise reinforced concrete frame-shear wall structure failed in different position.Referred to the basic requirements against progressive collapse provided by JGJ03-2010,Based on alternate path method ,This paper presents an analysis procedure that made Linear static analysis to a modal of 24-storey frame-shear wall structure designed according to the current code with SAP2000.The results show that once the edge column failed ,the structure will collapse.However,the corner shear wall constitute little threat to the progressive collapse.After the local members failed ,the lower part of the building contribute to the load path and it can results in axial force ruleless in beams,which make against to load bearing if they are tensile forces.The concentrated tensile stress appears around the continuous beam,and it is possible to be broken early after local member failed if close to the failed shear wall.
