【摘要】 爆炸荷载是建筑物遭受恐怖袭击时常见的冲击荷载.研究了在球面网壳设置玻璃采光区对建筑物泄爆效果的影响，以及不同种类玻璃的泄爆效果.结果表明在网壳结构上设置玻璃采光区后，无论是结构的最大位移还是杆件的塑性发展，都会随着采光面积的增大而下降，下降的程度与采光面积增幅近似呈线性关系，而且部分杆件进入塑性的时间有所滞后.当采光区的材料由普通玻璃改为钢化玻璃后，虽一定程度上起到了泄爆作用，但由于钢化玻璃的强度大于普通玻璃，泄爆能力降低.更多还原

【Abstract】 Explosion loading is a common impact load when buildings are under terrorism attack. This paper analyzes the influence of glass lighting area on the explosion venting effect of buildings and the explosion venting effect of different types of glass. The analysis results show that the maximum displacement of the structure and the plastic development of members will decrease with the increase of the lighting area. The degree of decrease takes on approximately linear variation with the increase of the lighting area, and the time for members of reticulated structures entering into plasticity has lagged behind. When the material of lighting area is changed from ordinary glass to toughened glass, although it helps venting explosion to a certain extent, the explosion venting capacity is actually reduced because the strength of toughened glass is greater than that of ordinary glass.更多还原
