摘要
为便于形态创构方法在工程设计中的应用,有效改善框架结构的抗侧刚度,本文提出一种"先增后减"的创构策略来寻找其合理的支撑分布.在该创构策略中,结构演化从简单结构开始,可快速有效地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用于表征水平荷载作用下的构件效率,并在该创构策略中进行应用.算例表明,此效率指标和创构策略对寻找框架结构有效支撑效果良好.
In order to facilitate the design application and seek a reasonable layout of the braces, an “elimination afteraddition” evolutionary strategy is put forward to improve the lateral stiffness of frame structures. In this newevolutionary strategy, which adds elements first, then removes them, the structure evolution starts from a simplestructure to seek an efficient force transmission path more effectively. Meanwhile, an improved efficiency indicator isshown 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 effectivelayout of braces can produce good effect.
