摘要
本文对超静定桁架的优化设计,提出了一种简捷的内力重分析方法,文中根据有限元理论,详细推导了修改方案后内力的显示表达式,并在微机上进行了实例计算。
A simple and direct method of reanalysing the internal forces
for the optimization design of statically indeterminate truss is
put forward.Expressions of the internal forces of the modified
plan are deduced in detail by the finite element theory,with an
example computerized.
