Optimal Design of Section Size and Pre-stress of Truss String Structure
摘要
Abstract
To study the optimal design of truss stnng structure in terms of two variables of section size and prestress, we establish an optimized mathematical model with the minimum structure weight by considering the constraint conditions of structure under the pre-stressed and loaded situations. To study the issue, the determination of prestressed value will meet the requirement of minimum weight and the arch camber design under condition of displacement constraints. Meanwhile, local stability of pressure-poles specified by Code for Design of Steel Structure is also con8idered in stress constraint condition of optimization model, which ensures the results are applicable in the reference of practical engineering design.关键词
