将集约几何规划法应用在连续梁和刚架的主体优化设计中，计算了两跨连续梁和门式钢框架，均得到满意结果。
A reducible geometric programming is applied to general design of optimum continual beam and frame. Two span beam and steel door-frame are calculated and give satisfactory results.
外部钢框架进一步简化为半刚架和相应的弹性阶梯形等效弯曲杆的串联体系，这种简化模型能考虑柱轴向变形对结构动力反应的影响；
The external steel frames are simplified as a series of half frames and the core tube is modeled as a bending and shearing two spring system.
