| 摘 要： | 异形柱框架结构是近年来迅速发展起来的一种很有发展前景的新型结构体系.根据规范的方法对异形柱正截面承载力进行了分析,编写了相应的配筋程序,与PKPM相比较,结果较满意.在优化计算中,优化的目标函数为主体结构的综合造价,优化变量考虑全面,约束条件以现行规范条文为依据,并运用了多级优化的思想使得优化结果能更符合实际工程设计施工的要求,编写了异形柱框架结构多级优化程序.

| Abstract: | Special shaped R.C.columns have been used widely in civil engineering field in recent years on account of their superiority.In this paper,carrying capacity of special-shaped columns under bi-directional eccentric load is discussed and programs are developed as well.Compared with PKPM,the results are satisfied.The objective function is the cost of the major structure.The variables are extensive and the constraint conditions are based on the codes in force.Then,multi-level optimal design method based on the criteria method is introduced and grid-research method is in its search technique.Different efficient variables are set in different levels of optimal procedure,so that the optimal result conforms to the need of practical designing work.Finally,a column frame structure shaped multi-level optimization procedure is written. |
