斜撑或人字支撑型阻尼减震方案中阻尼器的安装位置和空间常常受限于工业工艺或建筑功能等方面要求,有时不能安装在最优位置处。隅撑式阻尼减震方案对空间的要求要稍小一些,但其变形幅度较小,需要布置较多数量的阻尼器。通过对单层单跨平面框架的理论分析和基于结构控制benchmark模型的数值模拟,对隅撑式阻尼减震方案的有效阻尼比、结构弹塑性地震响应的减震效果等方面进行了分析,结果表明:隅撑式阻尼减震方案在技术上是可行的,通过合理设计,可以获得与斜撑式阻尼减震方案相近的减震效果;其工程造价要高于后者,但受到的建筑空间限制少于后者,可作为后者的备选方案。
The installation position and space of the damper in the bracing or herringbone-supported damping damping solutions are often limited by requirements of industrial processes or building functions, and sometimes can not be installed at optimal positions. Vault suspension damping requirements of the space to be slightly smaller, but its deformation is small, the need to arrange a larger number of dampers. Based on the theoretical analysis of the single-deck single-span plane frame and the numerical simulation based on the structure-controlled benchmark model, the effective damping ratio of the yoke damping damping scheme and the damping effect of the structural elastoplastic seismic response are analyzed. The results The results show that the suspension-damping damping scheme is technically feasible, and the damping effect similar to the diagonal damping damping damping scheme can be obtained through rational design. The construction cost is higher than the latter, but the construction space Limit less than the latter, can be used as the latter alternative.
