Abstract Glass curtain walls are widely used in modern architectural design, the majority, of which are built using laminated glass. Shattering of these glass walls during natural gas explosions caused by accidental leakages create hazardous glass shards. This work therefore experimentally investigates the dynamic response of laminated glass during a gas explosion by varying the methane concentration, vent closure material, glass layer thickness, and PVB interlayer thickness. The results indicate that the closer the gas concentration is to 9.5%. The use of a stiffer venting material venting also caused a greater displacement of the glass, thus decreasing its resiliency. The PVB interlayer can bond the glass fragments together to restrain the flying effect. Furthermore, increasing the thickness of the glass, and PVB clamp layers improved the ability of the specimen to resist the gas explosion loads. These test results provide a reference for the design of explosion-resistant laminated glass design and accident prevention.

PVB夹层玻璃在甲烷-空气混合物泄放爆炸载荷下动态响应的实验研究

摘要 玻璃幕墙在现代建筑设计中应用广泛，其中大部分采用夹层玻璃建造。这些玻璃墙在天然气爆炸期间因意外泄漏而破碎，会产生危险的玻璃碎片。因此，这项工作通过改变甲烷浓度、通风口封闭材料、玻璃层厚度和 PVB 夹层厚度，通过实验研究了气体爆炸期间夹层玻璃的动态响应。结果表明气体浓度越接近9.5%。使用更硬的排气材料排气也会导致玻璃的更大位移，从而降低其弹性。PVB 夹层可以将玻璃碎片粘合在一起以抑制飞散效应。此外，增加玻璃的厚度，PVB 夹层提高了试样抵抗气体爆炸载荷的能力。这些测试结果为防爆夹层玻璃的设计和事故预防提供了参考。
