Study On Earthquake Resistance Impact And The Cracks Of The Infilled Wall To The Infilled Wall Frame Structure

"5·12" Wenchuan earthquake was the one of the strongest earthquakes since the founding of our country. This earthquake caused huge casualties and property losses. In this earthquake,many of infilled frame structure buildings collapsed or was severely damaged.Recently, the infilled frame structure system was widely used in building construction because of flexible layout. The infilled frame structure,which is composed of beams and colums, belongs to frame structure. The infill walls of the infilled frame structure are generally believed that they have not overall impact on the structure. In The the infilled frame structure,the main frame of Infilled frame structure is reinforced,and the infill wall s is considered as the component that is used for the division of space.The cracks of masonry infill walls are quite common in infilled frame structure. The cracks of infill walls seriously affect the use of buildings function. The cracks of infill walls can cause the prone to the wall, hot and cold bridge effect,effect the waterproof of buildings, insulation effect and the beauty. In the areas, whose temperature have larger difference between day and night, exterior decorations usually drop by the cracks of the framework, which seriously affected the use, quality and artistic. At the same time, study on the the material of the walls can provide effective data for the study of land resources optimized, the sustainable development, research of new materials,and it can also be usefullto promote the development of new building materials.
