Abstract

A method of optimal design of damped structures under dynamic loads is developed, and several illustrative problems for minimum-weight design of planar frame structures under impulsive external forces or ground accelerations are studied. In order to analyse dynamic structures, the finite element method and modal analysis technique are used, and structural damping is included in terms of modal damping ratios. For numerical optimization, a gradient-type algorithm based on the state-space approach in optimal control is utilized.

阻尼动力结构的优化设计

提出了一种动力荷载作用下阻尼结构的优化设计方法，研究了脉动外力或地面加速度作用下平面框架结构的最小自重设计的若干实例问题。为了对动力结构进行分析，采用了有限元法和模态分析技术，并以模态阻尼比的形式考虑结构阻尼。在数值优化方面，采用了基于最优控制中状态空间方法的梯度型算法。
