On 12 May 2008, a magnitude 8.0 earthquake happened in Wenchuan, Sichuan province, China .It was the most serious earthquake in china since 1949, causing very huge casualties and engineering damages to the buildings. In the earthquake, a reinforced concrete frame structure of Beichuan Hotel in Beichuan County collapsed completely because of the unsuitable arrangement of column network, and the engineering damage was characteristic. In the paper, the properties of material nonlinearity were considered ,the nonlinear analysis model of reinforced concrete frame structure was established, the time history analysis and nonlinear static analysis were used during inelastic stage, the main cause of structural destruction was obtained, the influence of the arrangement of column network on the structure was discussed.Therefore ,the results can provide valuable reference for the seismic design of reinforced concrete frame structure.

Reinforced Concrete Frame Structure

The paper describes the dynamic and static analyses and design of a four storey ductile reinforced concrete frame structure isolated from the foundations by elastomeric bearings incorporating lead energy dampers. Results from inelastic, time-history analyses for the isolated and non-isolated structure are compared for several input earthquake motions. The benefits of energy dampers in reducing the isolated building's response (shears, plastic hinge demands and interstorey drifts) are detailed. Differences from conventional ductile design and detailing as well as design recommendations are included.

Reinforced Concrete Frame Structure

This article mainly studied the seismic response of high-rise RC frame and the damping effect with viscoelastic damper. Taking a reinforced concrete frame structure of 12 layers as the research object, six schemes of damper installed were designed and the dynamic characteristics of these schemes were analyzed. The time history response analysis of 3D Tianjin waves was studied for the six schemes under frequent earthquake. The results show that seismic capacity of the structure could be significantly enhanced with dampers under frequent earthquake. Meanwhile, different damper installations also can make the structures have different damping effect.

Isolation Device

The multi-storey reinforced concrete frame structure used lead rubber pad as the base isolation device. The paper had modal analysis of base-isolated multi-storey reinforced concrete frame structure using the ANSYS software. Comparing the frequency and vibration mode before and after isolation under El-Centro wave, It concluded the leader rubber pad have seismic isolation effect for multi-storey reinforced concrete frame structure .
