摘要
桥梁结构计算的一种有效方法是梁格法,虚拟横梁的截面特性取值是梁格法分析结果可靠性的关键之一,但是缺少规范的取值方法。梁格法虚拟横梁截面特性取值主要有四种方法,可得出5种截面特性取值。铰接板法的单梁计算结果分析表明,第4种取值时的结果与经典铰接板单梁计算模型计算结果最为接近。
An effective method of analyzing bridge structure is grillage method. The reliability of grillage method depends on the section properties of virtual transverse beam, but the property is lack of a standardized value. Four main methods are available to get five property values. Calculation results of single beam by hinge slab method show that the result calculated by using the fourth value is closest to that got by the typical model.
