摘要
介绍了常用的玻璃材料 ,采用断裂力学的方法研究了荷载的时间效应对玻璃材料强度的影响 ,总结了应用玻璃的新型结构 ,并针对点式玻璃幕结构侧向刚度不足的弱点 ,提出了支撑钢结构和玻璃面板共同工作的理论和相应的有限元分析公式 ,通过计算比较 ,得出了两者共同工作可提高结构侧向刚度两倍以上的结论 .
The paper introduces the usually used glass material and studies the effects of load-duration on the strength of the glass material.After analyzing the new architecture using glass and pointing out the insuffictent lateral stiffness of the dot point glazing structure,the authors puts forward the theory of the joint work of the steel support structure and glass panels,and the corresponding FEM analysis formulas.The calculation and comparison between the examples show that the joint work can provide a more than two fold lateral stiffness.
