OPTIMAL LATERAL DEFLECTION DESIGN OF TALL BUILDINGS OF FRAMES AND SHEAR WALLS
-
摘要: 提出了考虑侧移约束的高层框架剪力墙结构的最小重量优化方法,以取代以往对杆件的繁琐且不可靠的手工调整。对一些实际情况如设计变量的离散性问题作了合理的考虑。所提出的方法可有效地应用于高层建筑的抗侧移设计中。Abstract: A robust computer procedure for weight minimization of high-rise portal frames and shear walls under the deflection constraint at various locations is presented. It replaces the conventional tedious and unreliable manual assessment for numerous members. Several practical considerations such as the discreteness of design variables are included in the optimization procedure. The method is readily used in practical optimization design of steel and reinforced concrete structures against the deflection limit.
