| 摘 要： | 文章通过一加层工程实例,采用有限元软件MIDAS/Gen进行时程分析,对屈曲约束支撑在不同强度地震作用下的工作性能和耗能性能进行了分析。结果表明,屈曲约束支撑在加层结构中有良好的耗能性能,尤其在大震作用下,通过滞回变形消耗地震能量,保证结构安全与可靠。

Working Performance Analysis of Buckling-restrained Brace in One Storey-adding Engineering |
| |
| Abstract: | Through one case of storey-adding engineering, and the finite element software MIDAS/Gen to do time-history analysis, the working perfor-mance and energy dissipation performance under the earthquake waves with different strength are analyzed. The results show that the buckling-restrained brace in the storey-adding structure has good energy dissipation performance, especially under strong earthquakes, the seismic energy consumption by hysteretic deformation can ensure the structure's safety and reliability. |
