(1 School of Civil Engineering and Architecture, Southwest Uruversity of Science and Technology, Mianyang 621010, China; 2 Wenchen Architectural Engineering Limited Liability Company of Mianyang, Mianyang 621010, China)Abstract: Finite element software was adopted to generate two analysis models of RC structure which one is the origin structure and another is added HADAS, and analyzed the shock absorption effect and characteristics of HADAS based on the dynamical and time-history analysis. The result shows that:1)HADAS willimprove the integral stiffness of structure; under the earthquake effect, it has great effect on the acceleration response and displacement response, shock absorption obvious.2)HADAS has great effect on increase the ductility of structure, can reduce the number of plastic hinge of the structure under the action of the rarely met earthquake.3)Through dynamic numerical simulation, showed that the RC structure adding HADAS is very applicable, especially for the system structure wluch needed improve earthquake resistant behavior integral, the shock absorption effect is obvious.
Keywords: HADAS; RC high-level framework; shock absorption; dynamic performance; numerical simulation
