摘要:
采用有限元法,对玻璃板厚变化的夹层玻璃在长、短期静力和冲击荷载作用下的变形性能进行模拟计算,计算结果与相关文献试验结果符合较好.进一步的计算分析表明,荷载作用类型及持续时间、支承方式和内外层玻璃板厚变化,是影响夹层玻璃整体变形性能的主要因素.夹层玻璃在爆炸荷载作用下,其弯曲刚度比静力荷载下的弯曲刚度大,框支玻璃的抗爆性能好于点支承玻璃的抗爆性能.根据模拟计算,对现行规范夹层玻璃等效厚度的计算公式进行修正,给出的夹层玻璃等效厚度计算公式适用于不同支承条件.
Abstract:
The finite element model is used to simulate the deflection behavior of laminated glass with different thickness under short-term or long-term static load,and impact load,the calculation results conform well to the experimental data in references.Further study shows that the main factors affecting the deformation properties of laminated glass,are load type,load duration,support condition and glass ply.The flexural stiffness of laminated glass under blast load is larger than that under static load,and the performance of blast resistance of frame-supported glass is better than that of point-supported glass.According to the simulation,the equivalent thickness formula in current code is amended.The suggested formula is applicable for different support conditions.
