Abstract


The multi-channel seismic line of defense in seismic performance of frame-shear wall structure is a major issue in the seismic design of shear wall structure. In the implementation process of the multi-channel seismic line of Frame shear wall, taking into account the structural stiffness degradation of will cause the internal forces’ re-distribution problems, the multi-channel seismic line of defense of the overall structure will be greatly affected.This paper, by static Pushover methods and through the MIDAS finite element analysis software, analysises some models on the influence of the degradation of local defense of the structure with some parameters. Then it summarizes the influencing factors of the internal force distribution of frame shear wall structure, so as to provide some reference to achieve the multi-channel seismic line of defense of the frame-shear wall structure, and provides some practical guidance on the actual design and analysis of frame-shear wall structure as while.In this paper, through structural ductility design theory,it leads to the thought of multi-channel seismic line of structure, and conducts a certain amount of theoretical explanations of multi-channel seismic line of defense. Then it introduces the current important ways the structural analysis--Pushover method, also introduces the finite element analysis software used in in this paper-MIDAS. Finally by the software, multiple models are compared and analyzed to study the affect of the structural stiffness characteristic values and inter-story drift angle of the structure on internal force distribution. This paper Summaries certain rules, At the same time some research is done on the adjustment of normative framework of the internal forces of structural formula.
