当与其它相比结构的系统在全世界在过去主要的地震期间损坏了时,钢空间结构的严重损坏很少被报导。在在中国在 2013 M7.0 Lushan 地震期间被损坏的闹市区 Lushan 县的钢空间结构的二个体育馆被调查,观察在这份报纸被总结。这二钢空间结构的典型损坏从对中等严重。中等损坏包括全球弄弯和固定连接的脱臼捆绑锚螺栓的成员,和无弹性的延伸并且支持的柱脚盘子滑动。严重损坏包括本地弄弯,和锚螺栓和焊接的破裂失败引起的成员骨折。这二结构的结构的损坏的分发详细被描述,未来研究机会被建议。
Severe damage to steel space structures is rarely reported when compared to other structural systems damaged during past major earthquakes around the world. Two gymnasiums of steel space structures in downtown Lushan County that were damaged during the 2013 M7.0 Lushan earthquake in China were investigated and the observations are summarized in this paper. Typical damage to these two steel space structures ranges from moderate to severe. Moderate damage includes global buckling and dislocation of bolted connections of truss members, and inelastic elongation of anchor bolts and sliding of pedestal plates of supports. Severe damage includes member fracture caused by local buckling, and fracture failure of anchor bolts and welds. The distribution of structural damage to these two structures is described in detail and future research opportunities are suggested.
