Multi-storey Residential New Composite Structure Studied

The traditional structural system of clay brick of the multilayer residence structural system has been forbidden because of its destroying the farmland seriously, consuming the energy in a large amount in our country. The theoretical calculations and analyses on the multilayer house new style compound structure system aimed at the question have been already done. Therefore, as one of a new style structural system, it is essential to try out the experimental investigation. In this paper, it is studied on the vertical load and low-cycle and repeated loads experiments which are used in the multilayer house new style compound structure it mainly comprises as follows:The new style compound structural system composed by reinforced concrete small column, beam and chevron (a) braces is suggested, and then substitutes for brickwork wall. In this paper, the research generalizations both domestic and abroad about frame braces structure have been summarized, becouse the compound structure system formally is similar to the frame braces structure. Stress behavior of the new style compound structure is different from the frame brace structure The basces are used to resist vertical loads first(the braces were served as the pivot of the girder), and then the braces of the compound structure are mostly used of resisting side or earthquake action. It has been formed of multitrack antiknock system with " strong post, middle girder, feebleness brace " analogousing to the frame braces structure.These problem serves as "Henan province natural science fund item " (511050400) , and "Henan province education department natural science research item" (200510459055) .According to theoretical analysis of member sections, the test model specimen was designed adopting 1: 2 scale model. Testing programs supervised test of vertical loads and low-cycle and repeated loads were designed out on basis of computational cracking, yield load as well as all levels earthquake effects.
