用Trefftz型边界解法分析了中厚板弯曲问题,发现了一类新的、因Trefftz函数溢机引起的“自锁现象”,并提出了一种消除这类自锁问题的“变量减缩法”。 相似文献

本文提出在侧向荷载作用下高层建筑联肢剪力墙的分析.假设楼板为刚性楼板,剪力墙可以改变厚度.我们应用有限条法来分析联肢剪力墙平面结构.计算结果是满意的.与有限单元法比较具有下列优点,如输入数据简单,需用内存不多及汁算时间短.因此,有限条法适用于小型电子计算机或微型计算机. 相似文献

带缝钢筋混凝土高剪力墙抗震性能研究 总被引:3,自引:0,他引:3
阐述并总结了作者新近研制的一种抗震自控结构——带缝钢筋混凝土高剪力墙的设计概念和相关研究成果;分析评估了影响带缝剪力墙性能的主要因素,指出了作为结构关键控制部件——沿缝槽方向的剪连结对结构整体抗震表现的至关重要的作用,当剪连结的设计恰当时,即可使其在地震中吸收最多地震能量,使带缝剪力墙的地震反应得到最佳控制 相似文献

A composite structure-internal liquid element is proposed in this paper. Through the use of analytical functions in two orthogonal directions, the three-dimensional problem of coupled structure-internal liquid vibration is reduced to a one-dimensional one, resulting in a drastic reduction in computing efforts.Cylindrical and conical frastum composite elements are proposed to suit different problems, and examples are presented to demonstrate the accuracy of the method. 相似文献

Architectural sandwich panels with thin-walled cold-formed steel facings and rigid foamed insulating core are becoming more and more popular as enclosures for system buildings. In this paper, the structural behavior, including flexural stresses/deflections, flexural wrinkling, axial stability, thermal stresses and vibration, is presented, summarizing more than a decade of research. Methods used are analytical (boundaryvalued approaches), numerical (finite-strip, finite-layer, finite prism approaches) and experimental (full-scale testings). Key equations are formulated, and results by different methods are compared. 相似文献
