中文摘要：

采用数值试验的方法分析了基于蒙皮效应的钢梁在静力情况下的力学性能．给出了该新型钢梁的应力分布情况，并与H型钢梁、箱型钢梁的承载能力进行了比较．研究表明，相同跨度、相同质量的新型钢梁具有更高的承载能力，并且随着跨度的增加，合理设计的新型梁的承载力具有更加明显的优势．

英文摘要：

Numerical simulation was used to analyze membrane effect. The stress distribution of the beam was the mechanical property of steel beam based on given and compared with those of steel box-beam and steel H-beam. The results show that, with the same span and mass, the new beam has higher bearing capacity, and with the increase of the span, under rational design, the superiority of the bearing capacity is more evident.
