依照我国新修订的《钢结构设计规范GBJ17—88(报批定稿)》设计实腹式压弯构件时,一般需根据经验或参照己有资料试选出截面型式和截面尺寸,然后进行验算,不满足时再调整重算,一直到合适为止.本文继承传统设计法的优点,提出一种主要根据内力选择实腹式压弯构件截面尺寸的方法,可减少试算工作量,供教学和工程设计时参考. In accordance with China’s newly revised “Steel Structural Design Code GBJ17-88 (Approved for Approval)” for the design of solid abdominal bending elements, it is generally necessary to select the cross-sectional type and cross-sectional dimensions based on experience or with reference to their own data, and then conduct a calculation. When it is satisfied, it is adjusted again until it is appropriate. This paper inherits the advantages of the traditional design method, and proposes a method for selecting the cross-sectional dimensions of the solid-body compressive and bending members mainly based on internal forces, which can reduce the trial calculation workload for teaching and engineering design.
