Test Study Of Asesmic Property On Frame-supported Multi-ribbed Composite Wall Constructure With Commodious Space At The Bottom

With the rapid development of the construction in our cities, in the buildings which are located in cities, houses with commodious space at the first storey(s) are widely spread . At present, the main form is Lower Frame-Shear Wall Structure with Upper Masonry Structure (LFSWSUMS), However, due to masonry structure's high self-weight and low aseismic capacity, the total height of the building and the number of storeys are strictly limited. The paper probed the applying of Multi-Ribbed Slab with Outer Light Frame Structure (MRSOLFS) to the upper structure of buildings with commodious space at the bottom and the feasibility of replacing LFSWSUMS with Frame-Supported Multi-Ribbed Composite Slab Structure (FSMRCSS).Firstly, the paper carried out test study base on the pseudo-static test under horizontal loads on four two-spanned model members of FSMRCSS, including three 1/2-scaled two-storeyed models and one 1/3-scaled three-storeyed model. By the test study, the paper analyzed the test results, including analysis on mechanical property of the constructure under vertical loads, and failure mode, deformation capacity, aseismic performance under horizontal loads and constant vertical loads. The paper also compared LFSWSUMS with FSMRCSS on aseismatic property. Secondly, the paper created compute model of space beam system constructure on the FSMRCSS,and studied stress distribution in FSMRCWB under vertical loads and under elastic earthquake force with constant vertical loads respectively. At last, the paper, based on mechanical analysis, proposed anti-shear force formula of the composite wall and internal forces formulas of the beam under vertical loads, and explored theaseismatic design method of the FSMRCSS.All in all, the paper drew the conclusion that FSMRCSS is better than LFSWSUMS on aseismic performance. FSMRCSS is a new ideal asesmic constructive systerm.
