EXPERIMENTAL AND NUMERICAL STUDIES ON BLAST RESISTANCE OF LAMINATED GLASS
In this paper, site blast tests and numerical studies on simple supported laminated glass panel have been carried out.
Firstly, a series of site blast tests are conducted considering different compositions of glazing and different loadings.
Then, nonlinear dynamic responses and failure modes of simple supported laminated glazing are numerical analyzed. Based on the findings from experimental and numerical studies, critical states of laminated glass in both impulsive region and quasi-static region of P-I diagram are defined. Theoretical formulae for pressure asymptotes and impulse asymptotes of laminated glass under different damage levels are then proposed based on energy method. The theoretical results are validated against site blast and numerical tests and can provide guidance for engineering blast resistant design for laminated glazing.
