Research On Anti-Seismic Behavior Of Aerated Concrete Block Bearing Walls With Opening

Aerated concrete block is a kind of new building materials which is advocated by government and it is also a kind of green and environmental protection materials. It has the characteristics of light, thermal insulation, economy, low carbon, energy saving, easy processing. Aerated concrete block is a kind of materials which has the potentiality.In the future, it will gradually replace clay solid brick and become the main wall materials in the market of building.The structure which is built by clay solid brick, because of big gravity, it caused a great poor effect in the earthquake. At the past, we found the masonry structure has a serious damage in the earthquake, especially the hole which is in the walls with opening, it is weak parts to resist the earthquake, it is an important meaning that aerated concrete block which is a light and high strength material is used in the structure. It can reduce damage which is caused by the earthquake.Contrast to previous masonry structure, because aerated concrete block is a light material which own small gravity, it is beneficial to resist the earthquake. Constitutive relationship of aerated concrete block shows that it has good elastic-plastic, it is also beneficial to improve the overall seismic performance. In this paper, based on the reference to international and domestic research, then do the research on anti-seismic behavior of aerated concrete block bearing walls with opening, the specific contents are as follows:First, finite element analysis model of aerated concrete block bearing walls with opening is built. It includes the scheme of no constructional, the scheme of constructional column, the scheme of horizontal beam, the scheme of horizontal reinforcement. The vertical force is loaded on the model of wall. Then horizontal force simulation for cyclic loading is loaded too. At last, cracking load, cracking displacement, ductility coefficient of the wall are calculated to discuss seismic performance. Four models are contrasted to discuss that which scheme is more effective to improve the overall seismic performance under different vertical force. At last, provide effective reference for earthquake region.In this paper, it does the research on anti-seismic behavior of aerated concrete block bearing walls with opening, analyses the distribution of internal force and failure characteristics, provides theory reference for scholars.
