不等跨连续梁截面尺寸的优化

Section Size Optimization Of Unequal Span Continuous Beam

分析了不同截面对梁结构内力、截面设计的影响,针对不等跨连续梁提出最优线刚度比的概念,并通过PKPM结构设计软件计算出不同截面下梁的框架内力,对比分析出梁的的最优线刚度比,以期达到不等跨连续梁截面尺寸的优化。

This paper analyzes the effect that different sections impact on beam internal force and section design. It puts forward the concept of optimum line stiffness ratio in allusion to the unequal span continuous beam, calculates frame inner force using PKPM structure design software to get the optimum line stiffness ratio and section size optimization of unequal span continuous beam.
