The Seismic Performance Analysis Of High Performance Concrete Joint

With the development of science, the people’s have not only satisfied with thebasic requirements of comfort. The stuctural engineers have been pressed upon moreand more requirements by the architects who had a powerful and unconstrained styleimagination.as the structure forms are diversified, the properties of materials shouldhave higher requirements and the study of high performance concrete started.Atpresent,there is considerable progress in the research of high performanceconcrete,many countries in the world have used high performance concrete in manylarge projects with a good effect.The loss is immeasurable under the action of earthquake.The failure of jointwhat may caused structure damege have been focused by many researchers.as oneimportant part,Even though there is a big distance in relevant theoryresearch.Undeniablly,the performance of joints will affect the seismic performanceof the structure.2kinds of high performance concrete based on was selected as the experimentalobject comparing with ordinary concrete C35,.The finite element analysis wasestablished by ABAQUS,considering tension compression stress strain relationship ofhigh performance concrete.pseudo-static test was applied on the threemodels.Thorough the comparing of three materials in stress distribution,hystereticcurve and energy consumption curve,stiffness degradation situation and ductilityperformancecould could be obtained,so as to evaluate the seismic performance of thehigh performance concrete after the elastic of the joint.
