摘要:
用等效剪力膜代替核芯筒洞口之间的连梁,把开洞的核芯筒结构模拟成为一个闭口的薄壁杆 .利用有限杆元法,提出开洞核芯筒结构动力特性分析的数值方法 .它考虑了扭转、翘曲尤其筒壁中面上的剪应变对动力特性的影响 .
Abstract:
A structure with perforated core walls is simulated as thin wall member with closed cross section, while the connecting beams between the openings of core walls are replaced by equivalent shear diaphragm with a certain thickness. A numerical method is then proposed by applying the method of finite member element for analysing dynamic characteristic of the structure with perforated core walls. The effects of torsion, warping, and shear strain on the middle surface of walls in particular on the analysis of dynamic characteristic are considered in this method. As compared with other numerical methods, the author’s method is demonstrated to be effective and feasible.
