NONLINER STATIC ANALYSIS ON SRC-RC VERTICAL HYBRID FRAME STRUCTURE

摘要

Transfer floor is a critical part of SRC-RC vertical hybrid flame structure.If the transfer floor is not designed rationally,frame models were liable to suffer mutation of rigidity and strength.The formation of weak-layer and and deformation concentration may lead to serious damage of transfer floor and collapse of structure under earthquake action.By using the large finite element software SAP2000,the seismic behavior of SRC-RC vertical hybrid frame structure was analysed.On the basis of research results,as the number of the floors of two-side transfer columns is the highest of all transfer columns and the middle transfer columns are much higher than others at the same time,the seismic behavior of SRC-RC vertical hybrid frame structure is the best of all models.The correlation coefficient of the horizontal bearing capacity is very small between global models and local models,but ductility coefficient exist highly linear relationship.The researched results can be applied by engineering practice.
