基于SLP方法的框架全约束优化

Frame structure optimization with all constraints based on SLP method

探讨了钢筋混凝土框架结构整体优化,并考虑了最大层间位移角的约束,在SLP优化方法的思路上,编制了框架优化程序和内力计算程序。通过算例验证,该方法对小型框架结构具有一定的可行性,而且可以看出,框架结构整体优化较能合理分配刚度。最后,对框架结构整体全约束优化提出了自己的看法。

The integrated optimization of reinforced concrete frame structure is discussed.Considering the constraint on drift angle of structure,program of frame structure optimization and structure analysis based on SLP（Sequential Linear Programming） method is worked out.The example shows that the method is viable to small frame structure and the distribution of stiffness is reasonable with the integrated optimization.Some opinions on integrated optimization of frame structure with all constraints is presented at the end of the paper.
