In order to achieve "energy-saving emission reduction", the objective of our country, making people’s life and property safety are guaranteed, solve the extensive use of brick as a result of consumption of land, destroy the ecological balance and a waste of resources, pollution of the environment and other issues, overcome traditional brick from major shortcomings such as large weight, poor seismic, not energy saving, study on lightweight thermal insulation wall slab and energy-saving insulation anti-seismic and lightweight building is a must.The paper describes the development status of energy-saving insulation anti-seismic and lightweight building at home and abroad, and related of technology research status, for currently residents building situation in China, such as brick form more, resources consumption large, poor of energy saving and seismic, uses lightweight thermal insulation wall slabs which independently develops, makes construction development of building with energy-saving insulation anti-seismic and lightweight, insulation system and structure system of constitute are given out.For optimal seismic performance of lightweight thermal insulation slabs, this paper has established steel frame-lightweight thermal insulation wall slab models, analyzed effects of different filling materials on seismic performance of wall. After analysis of modal, found that different filling materials will change the natural frequency and mode sharp of structures, affecting the dynamic response of structures under seismic waves. Under rarely and commonly seismic loads, different filling materials and filling ways, will have a greater impact on tensile compressive stress and shear stress of lightweight thermal insulation wall slab, thereby affect seismic performance of structures. For the purpose of improving seismic performance, we can change filling materials and filling ways of the wall.According to the characteristics of typical houses in surrounding rural area of Huainan, this paper established a simplified frame model of energy-saving insulation anti-seismic and lightweight housing, to dynamic time history analysis under rarely and commonly seismic, selection of interlayer displacement as an indicator to observe its structure’s reliability. Analysis found, regardless under rarely or commonly seismic loads, maximum interlayer displacements of structures are meet specification requirements. According to the deformation characteristics of structure, strengthening structure stiffness of one layer, reducing one layer’s height should be considered. And while improve reliable of structure connection, prevent damage of connection parts loose or material fatigue caused by reciprocating shaking of earthquake.
