The Dynamic Response Of Frame-shear Wall Structure Under Explosion Action

Explosion is a phenomenon of energy released at the moment.Buildings within the range of explosion seismic waves generated by explosions would burst around the heart caused some serious cracks effects may occur even collapse. If this negative effect is not effectively controlled, that will bring security risks to the structure after a long time. Therefore, the safety performance issues has become a subject of research is urgently needed which is in the explosion seismic wave structure. This article under the framework of the blast wave effect-Dynamic response of shear wall structures were studied, and the structure of power in different waves explosion were analyzed and compared the response of the system. In order to complete the framework of the explosion seismic waves frame-shear wall structure dynamic response analysis will be completed the following aspects:(1) First introduced to the explosion seismic wave to the frame-shear wall structure damage effect of dynamic characteristics and research status at home and abroad and the main workof the paper.(2) Detailed description the Principles and propagation path of explosion,introduced an explosion of seismic waves, the type and the explosion seismic wave propagation mechanism, factors such as the intensity of the explosion seismic waves.(3) By learning MATLAB program I know, in principle the basis of the use of artificial seismic waves on artificial,intended to explode explosion seismic waves and seismic waves through the line compared with the single point measured.(4) By using the finite element analysis software SAP2000build11-storey frame-shear wall structure model, numerical simulation analysis to study the dynamic characteristics of the seismic waves in the blast effect. Through artificial simulation framework for different seismic waves explode dynamite blast volume and different distances-the overall deformation and failure characteristics of frame-shear wall structures are analyzed to contingency basis, by comparing the results of the analysis of different structures of explosion seismic waves, draw explosion seismic waves affect different amount of explosives and blasting a different structure arising from the heart, which can obtain effective security structure of distance, and then propose a reliable protective measures.Finally, through the simulation results of the above can be made on the subject of this paper and the lack of a number of issues still need further research.
