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 application of morphological construction method in engineering design and effectively improve the lateral stiffness of the frame structure, this paper proposes a creative strategy of “increasing first and then decreasing” to find its reasonable support distribution. In the strategy, structural evolution begins with a simple structure, which can quickly and effectively find the effective force transmission path of the structure.An improved component efficiency index is also proposed to characterize the component efficiency under the horizontal load, and in the creative strategy The example shows that this efficiency index and creative strategy have a good effect on the effective support of finding a framework.
