弹簧式自复位防屈曲支撑的抗震性能
Study on seismic performance of self-centering buckling-restrained brace with springs
摘要
Abstract
This paper introduces a study designed to reduce the residual deformation of the conven-tional buckling-restrained brace ( BRB ) under strong earthquake and proposes restrained brace with springs( SCBRB) . This study involves analyzing the mechanism of the SCBRB, producing parameters se-lection method of the SCBRB, based on the maximum permissible residual deformation of structure, and applying numerical simulation to identify the seismic performance of self-centering buckling-restrained brace with springs( SCBRB) , the self-centering buckling-restrained brace with prestressing tendons and the conventional BRB, as in the case of strong earthquakes. The result shows that the proposed SCBRB is capable of achieving a greater reduction in the residual deformation of structure system than both the SCBRB and the conventional BRB.关键词
