The Performance Analysis Of The RC Frame Strustures With Seismic Isolation Device

Infrastructure refers to the upper structure and Foundation of the building between the isolation layer to extend the natural period of the structure as a whole system, increase the damping, reducing the input of earthquake action of the superstructure. It is a passive control system, compared with the traditional aseismic structure, mainly through seismic isolation layer to absorb and consume energy, and reduce earthquake responses.This article on laminated rubber vibration isolation cushion performance analysis, SAP2000using finite element software build a six-story reinforced concrete structure by linear and nonlinear time-history analysis, study on seismic performance of base-isolated structure and effect of absorbing vibration. For frame structures using space frame model, for laminated rubber bearings using simulation analysis of bi-linear spring Rubber Isolator. Models respectively, taking into account traditional seismic and seismic programmes in two forms, three kinds of seismic waves on its input, integration of data analysis, draw useful conclusions.Analysis of two kinds of structure, came to the base-isolated structure under seismic forces, acceleration, displacement and interlayer between layer shear compared to traditional aseismic structure has a very large decrease in significantly reduced the role of horizontal earthquake forces.Paper through the analysis of reinforced concrete frame base-isolated structure and research, reveals the characteristics of base-isolated structures in depth and superiority, for future seismic isolation technology to make contribution to the development of our country.
