双轴对称受弯工字型梁荷载与跨度和截面面积关系的分析及应用

ANALYSIS AND APPLICATION OF RELATIONSHIP OF LOAD,SPAN AND SECTION AREA OF BIAXIAL SYMMETRIC FLEXURAL I-SHAPED BEAM

推导得出双轴对称受弯工字梁的荷载、跨度和截面面积之间的关系。对钢梁两端不同的约束和不同荷载起主导作用的情况进行理论推导和算例比较,得到的荷载、跨度和截面面积之间的函数关系可靠准确,供工程设计人员参考使用。

The relationship between the sectional area,load and span of the double-shaft symmetry flexural I-shaped beam is deduced;theoretical derivation and numerical comparison are carried on to the situations that it plays a leading role to the different constraints and loads on the two ends of the steel beam,where the derived functional relationship between the load,span and sectional area is reliable and accurate,which provides a reference for engineering designers.
