英文摘要： The project is mainly puts forward a kind of new wall structure -lightweight concrete- cotton stalk fiber mixed desulfurization ash composite block wall structure which has bearing and heat preservation performance suitable for rural building. The composite wall structure with lightweight concrete hollow blocks for external formwork, have template function, in the block hole irrigation cotton stalk fiber mixed desulfurization ash have heat preservation material forming the whole casting composite wall structure, which set bearing and insulation performance as a whole. Main work: Study the best material ratio and production process of the lightweight concrete and cotton stalk fiber mixed desulfurization ash and the block type optimization research; Research basic mechanical properties and thermal properties of composite masonry, determine the working mechanism of composite block and the thermal calculation method of composite masonry wall; Study on pressure and seismic shear performance of composite masonry wall, establishing the calculating model and formula of pressure bearing and seismic shear capacity of composite block wall; By means of the wholeness and the elasto-plastic time-history analysis, the energy consumption analysis, the shaking table test, study the overall performance and the seismic performance of composite masonry wall structure, finally puts forward the design method and seismic structural measures of the composite masonry wall structure. This project will make due contributions to the development of villages and towns in Xinjiang and the west of china.
