由于其显著的开裂后承载能力，PVB夹层玻璃已被广泛用于建筑窗户作为安全玻璃。为了更好地了解爆炸荷载作用下框架式聚乙烯夹层玻璃的力学行为，设计并进行了一系列现场爆炸试验，旨在研究框架式聚乙烯夹层玻璃在不同爆炸荷载作用下的动力响应和破坏模式。测试了反射超压和位移时程。特别地，采用DIC技术记录了玻璃板的三维挠度场，这对于分析夹层玻璃板在爆炸荷载作用下的动力响应特性至关重要。识别出三种典型的破坏模式，即整体弯曲破坏、局部冲切破坏和混合破坏，并分析了相应的破坏机理。最后，测试结果被用来检查不同的设计方法的有效性。研究结果可为进一步的夹层玻璃抗爆性能分析和设计提供参考。
PVB-laminated glass has been widely adopted for building windows as safety glass due to its significant post-crack load bearing capacity. To achieve a better understanding of the mechanical behaviour of framed PVB-laminated glass under explosion, a series of field blast tests were carefully designed and conducted aiming to study the dynamic responses and failure modes of framed PVB-laminated glass subjected to various blast loadings. The reflected overpressure and displacement time histories were measured in the tests. In particular, DIC technology was adopted to record the 3-D deflection field of the glass panel, which is essential for analyzing the dynamic response feature of laminated glass panels under blast loading. Three typical failure modes, i.e. global flexural failure, local punching failure and mixed failure, were identified and corresponding failure mechanisms were analyzed. Finally, the test results were used to check the effectiveness of different design approaches. The results from this study can provide reference for further blast resistant analysis and design for framed PVB-laminated glass.
