| 摘 要： | 当民用高层建筑修建完成,若需采用加大截面法加固底层剪力墙,由于无法对恒载进行卸载,其加固属于被动加固形式。现行加固规范认为加大截面法以梁、板、柱为宜,故无相关推荐计算公式。该文分析了剪力墙被动式双面加大截面的受力机理,推导出轴心受压的计算公式,可为加固工程实践提供参考和借鉴。

Calculation Method of Axial Compression for Low-level Shear Wall with Passive Two-sided Enlarging Section |
| |
| Abstract: | When the construction of civil high-rise buildings is completed, if it is necessary to strengthen the shear wall of low-level by enlarging section, the strengthening method belongs to a passive reinforcement form for uninstalling load. The existing strengthening code indicates that it is favorable to take beams, slabs and columns in enlarging section, so there is no relevant formula to be recommended. This paper analyzes the stress mechanism of the shear wall being strengthened by passive two-sided enlarging section, and the axial compression formula for reinforcement is deduced. It can offer some references for engineering practice. |
