摘要
提出了蜂窝构件组成的轻钢门式刚架,并利用有限元软件ANSYS建模进行数值模拟分析,研究了蜂窝门式刚架的受力破坏过程、应力分布规律,并与扩张前的原实腹门式刚架的屈服荷载、极限荷载、梁跨中挠度等进行了对比分析。研究表明:扩张后的蜂窝轻钢门式刚架与原实腹门式刚架的破坏形式不同,前者的承载力及刚度比后者有大幅度提高。
A light-weight castellated portal steel frame was introduced,and its mechanical behavior was studied using ANSYS.The failure process,failure patterns and stress distribution of the frame were obtained by the finite-element method.The comparison about yield load,bearing capacity and mid-span deflection between the light-weight castellated portal steel frame and the pr-expansion solid portal frame was carried out,as well.Research results show that the failure patterns of the two kinds of portal frames are different;the bearing capacity and stiffness of the light-weight castellated portal steel frame are significantly improved compared to the pr-expansion solid portal frame.
