  • In this paper, an independently-designed system for explosion experiment is used to investigate the dynamic response law of hollow tempered laminated glass with plane size of 300 mm × 300 mm and 1000 mm × 1000 mm under explosive load. The influence of layer thickness of PVB glue, thickness of air layer, explosive quantity and explosion distance on the anti-explosive performance of hollow tempered laminated glass is analyzed. The results show that: (1) the anti-blast performance of hollow tempered laminated glass is enhanced with the increasement of the plane size; (2) for both large-size and small-size hollow tempered laminated glass, with increasement of the thickness of the PVB glue layer, both the overall strength of the structure and the load-bearing capacity of the sample increase gradually when the thickness of the intermediate air layer increases, the overall stability of the structure decreases and the anti-explosion ability become weaker; (3) changing the amount of explosives and the explosion distance has a strong influence on the dynamic response of the hollow tempered laminated glass. With the increasement of the explosive amount and the reduction of the explosive distance, the damage degree of the hollow tempered laminated glass increases gradually.
