摘要
针对高层建筑结构的特点,将虚功准则法与拉格朗日乘子法相结合,给出了基于造价最低目标的风荷载及地震作用下建筑结构整体位移约束的优化算法公式,并结合算例验证了该方法的整体优化性能。
Based on the characteristics of tall buildings,the paper used Lagrange rule method combined with virtual work criteria to achieves innovative developments in disposing wind and earthquake load under integral constraints.The results of case analysis show that the new method has good optimization convergence and practicality.
