| 摘 要： | 点支式夹层玻璃具有良好的安全性能,当与中空玻璃结合使用时可兼具节能、安全的特性.现行规范尚未考虑夹层玻璃PVB夹层的抗剪作用,似乎显得较为保守.本文从PVB层的性能出发,使用有限元方法对点支式夹层玻璃板的受弯承载性能进行了分析,数值计算与现有试验结果吻合得较好.结果表明,在短期荷载作用下,规范设计方法显得较保守,本文建议虽然在短期荷载作用下适当的考虑PVB层的作用,但考虑幕墙工作环境,设计不宜考虑其贡献.

| Abstract: | The point-supported laminated glass panel shows excellent safety property,and when combined with insulating unit it will satisfy both of the energy conservation and safety demands.Current code neglects the PVB interlayer's shear-resisting behavior and gets relatively conservative design results.Based on the PVB's mechanical property,this paper uses finite element method to analyze the point-supported laminated glass panel's bending behavior.The numerical calculations agree well with the experimental results... |
