Reserch On Flexible Building And Mechanical Performance Of SRC Pillar With Crisscross Section

In our country, as the rise of peoples'demand for utility of room space, the buildings had already been constructed can not fulfill residents'need any more: inconvenient to use corners decreases the usage factor of room space, locations of pipes of water, electric, heating and gas are not only interfere the elegancy of room, but also, waste space and hard to use. The joint of flexible building and SRC structure with special shaped section alleviates that problem, it fulfills the residents demand, and also improves the carrying and aseismatic capacity.By synthetically discusses different groups of peoples'demand for usage of room space so as to analyze reasons of demands for changing space and factors of setting space, introduce the flexible building system particularly. In the mean time, by listing the advantages of pillars with special shaped section and steel reinforced concrete structure, introduce the case using crisscross shaped SRC structure as basic element in the flexible building, which realizes the objective of changing room by combining basic elements and fulfills the residents'individual demand of living room.By using finite element method to simulate the calculate of reinforced concrete component and steel reinforced concrete component, so as to compare the advantage of latter to the former, at the same time, by observing points in the contact areas between steel and concrete, analyzing conditions and rules of friction between steel and concrete in the process of axes loading.
