Analysis Of Earthquake Response On Large Bay Multi-ribbed Slab Structure With Base Isolation

Multi-ribbed composite wall structure is a new energy-saving structure system, and has obtained stage result on the theoretical research and application study. However, in the earlier period, only middle and small bay multi-ribbed composite wall structures were studied. A thorough discussion should be aiming at whether this structure is adopted to the large bay structure. The paper combines multi-ribbed composite wall structure and base isolation technology to develop the analysis on multi-dimensional seismic response of base isolation structures and different factors affecting the stucture with base isolation.The main researches are follows:1. Make the multi-ribbed composite wall structure system and the base isolation technology to unify, and pick the SAP2000 analysis software to establish model. Earthquake response mechanism of the large bay multi-ribbed composite slab structure with base isolation and the structure without base isolation is analyzed. Then the application fesibility of the large bay multi-ribbed composite slab structure in strong earthquake district is verified.2. The paper study the earthquake response of the large bay multi-ribbed composite wall structure when input unidirectional, bidirectional as well as three directional earthquake and carried on the contrast analysis on the base of the results. All of those provided the basis for the structure computation analysis.3. Through the structure dynamic analysis, discuss the design parameter change of the shock isolation system and multi-ribbed composite wall, which bring influence to the structure overall earthquake resistance. Those provide the reference information for the reasonable selection shock isolation system and the structure optimum design.
