摘要
选择90 m跨钢拱桁架为研究对象,采用SAP2000对其平面内稳定性进行研究,研究中考虑了初始几何缺陷,不同荷载分布情况对结构屈曲承载力和变形能力的影响,研究结果表明,初始几何缺陷对拱桁架稳定影响较为明显。
Choosing 90 m span steel arch truss as the study object,using SAP2000 researched its plane within stability,in research considering the influence of initial geometric imperfection and different load distribution situation to structure buckling bearing capacity and the deformation ability,research results showed that,the influence of initial geometric imperfection to arch truss stability was very obvious.
