摘要:
为便于方法在工程设计中应用，改善框架结构的抗侧刚度，本文提出一种“先增后减”的创构策略来寻找合理支撑分布． 该策略结构演化从简单结构开始，有效寻找结构的高效传力路径． 同时还提出一种改进的构件效率指标表征水平荷载作用下的构件效率，并创构策略进行． 算例表明效率指标和创构策略对寻找框架结构有效支效果良好．
Abstract:
In order to facilitate the design applicationseek a reasonable layout of the braces, an “elimination after addition” evolutionary strategy is put forward to improve the lateral stiffness of frame structures. In this new evolutionary strategy, which adds elements first, then removes them, the structure evolution starts from a simple structure to seek an efficient force transmission path more effectively. Meanwhile, an improved efficiency indicator is shown to characterize the component efficiency under reversible lateral loads and is applied in the evolutionary strategy. The numerical examples show that the efficiency indicators and the morphogenesis strategy for finding the effective layout of braces can produce good effect
