摘要:
SRC-RC混合框架结构的过渡层处因强度和刚度的突变而影响结构的抗震性能。文章运用有限元软件SAP2000建立了13个SRC-RC竖向混合框架结构模型,对其进行静力弹塑性分析;从模型水平承载力、变形能力、结构位移基底剪力—顶点位移关系、塑性铰分布等4个方面,研究其对抗震性能的影响。结果表明:当结构过渡层处于中下部、两侧的过渡层柱位于楼层最高处,而中间过渡层柱位于楼层次之时,SRCRC竖向混合框架结构的水平承载能力最高,其较RC框架结构提高了398 kN;SRC-RC竖向混合框架结构过渡层柱从3~5层升至4~6层时,结构的平均延性系数提高2.44%;SRC-RC竖向混合框架结构形成了比较多的塑性铰,其可吸收地震释放的能量,避免了在罕遇地震作用下发生倒塌,具有较好的延性。
Abstract:
Because of the change of bearing capacity and stiffness, the transition layer of SRC-RC vertical hybrid frame structure is easy to form a weak layer, which will affect the seismic performance of the structure. In order to solve the problem, 13 structural models are established and the seismic performance of SRC-RC vertical hybrid frame structure which the number of floors of transfer column is not in the same floor is studied through static nonlinear analysis by using the large finite element software SAP2000 in this paper. This paper studies the Influence of transition layer form on seismic performance from 4 aspects which include horizontal bearing capacity、deformation ability、structure displacement base shearvertex displacement relation、plastic hinge distribution. The results show: the transition layer structure on both sides of the column when the highest floor, the central column of the transition layer, the structure of the horizontal bearing capacity is the highest, increased by 398kN compared with RC frame structure; when the transition layer column of SRCRC vertical composite frame is increased from 3-5 layers to 4-6 layers, the average ductility coefficient of the structure increases by 2.44%, indicating that the deformation capacity of the structure is improved; more plastic hinges can appear in the vertical hybrid frame structure models to absorb energy which seldom occurred earthquake action released before the structure is destroyed. So SRC-RC vertical hybrid frame structure with good ductility is able to withstand the rare earthquake and does not collapse.
