开洞核芯筒的弯扭分析

Bending and Torsion Analysis of Core Tube with Holes

根据VLASOV薄壁理论和有限元法对高层建筑核芯筒进行弯扭分析 .在分析过程中 ,将核筒视为开口薄壁杆件 ,将连梁视为影响构件 .将核芯筒的开口部分和带连梁的部分分开考虑 ,不再采用连续化假设 .本文的方法概念清楚 ,计算简便 。

The bending and torsion behavior of a core tube with holes is analyzed by Vlasov theory and the finite element method. In analysis, the core tube is considered as an opening thin walled element and the connecting beams are considered as the elements, which influence the core tube. The holes and connecting beams are separately considered, not using the continuous method.That the method presented in this paper is clear, simpler and higher precise.
