Further, damage identification is transferred into an optimization problem through sensitivity equations and solved by genetic algorithms. Different damages on 10-storey, 20-storey shearing-type numerical models and a 3-storey test frame structure are identified.
随后,利用模态参数敏感方程将多高层结构损伤识别转化为数学优化问题,运用遗传算法进行优化求解,分别识别了10层、20层剪切型结构和实验室三层框架结构的各种损伤。
The structure coordination and shear unlocking middle thick plate element is a problem to which people pay close attention in the finite element analysis of plate.
在板的有限元分析中,构造协调和无剪切闭锁现象的中厚板单元一直是人们所关注的问题和难题。
