摘要:
为了减小单层球面网壳在简谐荷载作用下的破坏形式判别中的计算量,避免反复试算,节约后处理时间,提出了利用响应面法计算结构可靠指标从而判别失效类型的方法:利用响应面法计算单层球面网壳在简谐荷载下基于位移失效模式的可靠指标; 建立可靠指标和破坏形式之间的明确对应关系; 获得判别单层球面网壳破坏形式的量化指标。研究表明,该方法能够准确地判别出结果,并具有高效率和实用性。
Abstract:
In order to reduce calculating workload of failure types identification of single-layer spherical shells under harmonic loads, avoid repeating calculation and save after-treatment time, reliability indexes were proposed to determine failure type of structure by using response surface method and the specific step included three aspects. Firstly, reliability indexes which accord to the response surface method of single-layer spherical shell based on displacement failure mode were calculated under harmonic loads. Furthermore, the specific corresponding relations between reliability indexes and failure types were established. Finally, the quantitative indexes were provided to determine failure types of structure of single-layer spherical shell. The research shows that the method can determine failure types accurately and is effective and practical.
