Abstract
Previous great earthquakes have performed serious structural damages to masonry structure, which also have caused great casualties and property damage, in order to enhance the structural anti-seismic class of civilian buildings, a new kind of combined structure form is introduced in the thesis, which is formed by two parts, masonry structure and special reinforced concrete shear wall structure. The reinforced concrete part can be effective in enhancing the anti-seismic performance of masonry residence, besides reinforced concrete tube structure can also become the nearest refuge when disaster occurred, even when the whole structure collapse, it can still remain relatively complete partial structures and a large space of survival. LS-DYNA, software of finite element, is used to study the structure, simulations of the response procedures of composite structure under earthquake load are made, as well as the destruction of composite structure. According to calculation and analysis, it can be known that this kind of composite structure can obviously improve seismic resistant capability, and the level of destruction is relative smaller, which can meet the requirements for fortification against earthquake that is "keeping intact in minor earthquakes, repairable in medium earthquakes, standing upright in major earthquakes"
