srss meaning in English
开平方
Examples
- The seism response analysis of aqueduct bridge is analyzed with modal superposition method based on response spectrum which participant mode of vibration chooses the former 1 0 steps and combinatorial method was srss
渡槽的地震反应分析采用振型分解反应谱法，参与振型取前10阶，组合方法用srss法，求得结构的地震作用效应。 - From above analysis , the thesis gets conclusions as following : ( 1 ) the frequencies of multi - tower building are so dense and the coupling in each mode is so evident that the cqc method instead of srss should be used to calculate the seismic action effect ; ( 2 ) torsion effects is distinct between the modes of asymmetry multi - tower structure and it is necessary to take translation - torsion coupling into account ; ( 3 ) the effect of the enlarged base rigid on the seismic properties is very big , the rigid ratio of the enlarged base to towers in asymmetry multi - tower structure should be designed in a proper range ; ( 4 ) the distribution of plane rigid is asymmetry because of the asymmetry layout of towers . the torsion effects of structure not only result in large torsion internal force in vertical element resisting lateral displacement , but also make large influences on the stress of transfer plate and near floors , thus it is necessary to strengthen those floors
通过上述分析，得出以下主要结论：多塔楼结构存在频率密集现象，各振型间耦联效应明显，地震作用计算应采用cqc组合原则而不能简单地采用srss组合原则；非对称多塔结构的振型中，扭转作用明显，平扭耦联效应值得考虑；裙楼刚度对整体结构的抗震性能影响很大，非对称多塔结构宜控制裙楼与塔楼刚度比在适宜的范围；非对称多塔易导致平面刚度分布不均匀，结构扭转效应不仅在竖向抗侧构件中引起较大的扭转内力，对转换层楼板应力有较大的影响，且延续至相邻楼层，对相应楼层均应采取相应的加强措施。
