STUDY ON THE RELIABILITY OF THE SLOPE DEFLECTION METHOD AND STIFFNESS METHOD FOR RC PLANE FRAME UNDER LATERAL FORCE

摘要

The purpose of this paper is to clarify the reliabiltiy of the solutions obtained from the slope deflection method (SDM) and stiffness method (SM) in the analysis of reinforced concrete frames.Firstly,two reinforced concrete cantilevers and a 3-span 3-story reinforced concrete frame were analyzed by the two dimensional FEM,in order to find the appropriate finite element mesh to obtain reliable solutions. Secondly,over forty reinforced concrete models under horizontal load were analyzed by FEM,SDM and SM.The results obtained from the SM considering rigid zone were found to agree well with those from finite element analysis.
