摘　　要：计论了经济断面异型角钢系列和优化断面尺寸的确定原则和方法。在计算机上用最优化方法优选出了全系列异型角钢的结构尺寸和截面力学参数。并算出每种规格异型角钢与对应热轧角钢相比的节材率为5～11％。使用该异型角钢有明显的社会经济效益。This paper discusses special-shaped angle steel series of economical profiles, determining principles and methods of optimum dimension of the profiles. Whole structural dimension series of the steel and mechanics parameters of the profiles have been chosen by optimization. Compared each type of the steel with its corresponding hot rolled one, the ratio of sparingly use of material is figured out between 5%-11%. Therefore, it has a distinct cconomical social benifit of using the special-shaped angle steel.
