本文介绍了夹层玻璃窗在风载木块冲击下易损性的室内试验和数值模拟结果。本研究考虑了重量为2公斤、4公斤和8公斤的木屑以9米/秒至35米/秒的速度撞击玻璃窗。对采用1.52 mm、1.88 mm、2.28 mm和2.66 mm PVB夹层的3mm厚浮法玻璃层对2000 mm × 1100 mm和1200 mm × 600 mm典型窗户的性能进行了评价。研究发现层间厚度对夹层玻璃窗在风载碎片冲击下的抗侵彻能力起主导作用。生成了不同厚度和尺寸夹层玻璃窗的易损性曲线。提出了一种基于室内观测的玻璃碎片预测方法。根据撞击碎片的质量和速度估计碎片的质量和发射速度。
This paper presents results of laboratory tests and numerical simulations on the vulnerability of laminated glass windows subjected to windborne wooden block impact. Wooden debris weighing 2 kg, 4 kg and 8 kg with a velocity of 9 m/s to 35 m/s impacting on the glass windows is considered in this study. Performances of typical windows of sizes 2000 mm × 1100 mm and 1200 mm × 600 mm with 3 mm thick float glass plies laminated by 1.52 mm, 1.88 mm, 2.28 mm and 2.66 mm PVB interlayer are evaluated. It has been found that interlayer thickness plays a dominating role in the penetration resistance capacity of the laminated glass windows subjected to windborne debris impact. The vulnerability curves of laminated glass windows with various thicknesses and dimensions are generated. A predictive method based on laboratory observation is also developed to estimate glass fragments induced by debris impact. The fragment mass and launching speed are estimated with respect to the impact debris mass and velocity.
