平行弦式钢桁架控制挠度的简便计算法

摘要

The characteristics of force and disformation between parallel-chord steel truss and simple beam use in petrochemical plant pipe support were analyzed and compared. A convenient method for calculating control deflection was proposed.%对石化装置管架中常采用的平行弦式钢桁架与相应简支梁的受力特征及变形特点进行了分析比较，提出了控制挠度的简便计算法。
