相贯铸钢节点的有限元分析

he preliminary analysis and study on large steel casting intersecting joints design and force conditions combined with a Steel Reticulated Shell bottom chord joints design example of a high-speed railway central station. Study the distribution of joints structure stress by finite element numerical simulation. And then finds out the design parameters which has great influence on the maximum stress of joints by further orthogonal test numerical simulation. To Provide reliable basis for making relevant standards about intersecting steel casting joints design.
