给排水建筑物侧向刚度突变问题的有效方法研究

Research on the effective measure based on the abruptness of lateral stiffness in special buildings

给排水建筑物由于其不规则的结构形式常导致侧向刚度突变问题,针对这一问题以某污水处理厂细格栅为例进行分析,通过对柱截面加大和交叉斜支撑两种加强措施的比较,选择斜支撑作为合理、有效的加强方案,并为类似工程提供了参考。

This research focuses on studying of the abruptness of the lateral stiffness in supply and drainage buildings that often caused by the ir- regular structure. A building of fine screen in a sewage treatment plant is selected as an example to analyze this problem, and two methods inclu- ding increasing the column section and cross struct are applied as the strengthening measures, by comparison the strengthen effect of two kinds of measures, cross struct as the rational and effective measure. This study could also provide a reference for similar projects.
