点支式幕墙夹层玻璃承载性能的试验研究

本文进行了点支式幕墙夹层玻璃承载性能的短期试验和长期试验，测得了点支式夹层玻璃的荷载-位移及荷载-应力曲线。并且得到了夹层玻璃在一定荷载作用下位移和应力随时间变化的关系曲线，分析了夹层玻璃的蠕变性能。试验值与规范值的综合分析表明现行规范对点支式夹层玻璃的设计计算偏于保守。本文工作为今后规程的进一步完善和修订做了一些探讨。

Test Study of Load-Bearing Capacity for Laminated Glass in Point Supported Curtain Wall

In this paper, short-term and long-term experiments on the load-displacement and load-stress curves of laminated glass are carefully conducted. And displacement-time and stress-time curves are obtained. The effect of long-term load on load-bearing capacity of laminated glass is analyzed. Comparison is made between the results of experiments and from the current code. It shows that the current code will lead to conservative design results. The work of this paper will be helpful to the further improving of the current code.
