摘要
针对一既有高层建筑剪力墙开洞后加固的工程案例,进行有限元分析.研究结果表明:剪力墙开洞后的承载能力明显被削弱,在洞口附近区域出现应力集中现象.采用粘贴钢板加固开洞口处,可有效改善其应力集中现象,恢复墙体的极限承载能力,收到较好加固效果.
This thesis uses ANSYS to make a finite element analysis based on the engineering case of a high-rise shear wall with opening reinforcement.The result shows that the bearing capacity of shear wall with opening declines greatly and there appears stress concentration around the hole.What's more,by reinforcing the shear wall opening with paste plate,it will reduce its hosted force and the ultimate bearing capacity of the shear wall will be recovered,which may bring about good effect of reinforcement.
