摘要:
九寨沟7.0地震给九寨沟地区建筑结构及非结构构件造成了严重破坏。本文主要涉及调查区域包括漳扎镇、甲藩古城、若尔盖县阿西茸乡、求吉乡及包座乡等。主要调查框架结构、砖混结构、大跨空间结构以及木结构的非结构构件震害。此次调查的结构多数是2000年以后建造,8度设防,在2008年汶川地震中主体结构和非结构构件均未受到影响。在此次地震中,非结构构件大量损坏,破坏主要以框架、砌体填充墙开裂或变形或局部倒塌、吊顶脱落、地板隆起、吊顶设备掉落、玻璃震碎等震害为主。调查结果表明,与以往地震不同,VIII度区内仅有的三个大跨度结构均发生不同程度的破坏,其中一个结构出现节点破坏,此次地震中大跨空间结构非结构构件震损尤为明显,非结构构件设备损失最为严重。另一个不同于以往地震震害的是位于VI度区山坡上的木结构非结构震害明显比坡下要严重一些。
Abstract:
Building structures and nonstructural components in Jiuzhaigou region were damaged severely during Jiuzhaigou Ms 7.0 earthquake. Zhangzha town, Jiafan holiday resort, Xirong town, Qiuji town, Baozuo town were investigated in this paper and the seismic damages of nonstructural components of reinforced concrete frame, masonry, large span structure, wooden structure were studied. Most of the structures were built after the year 2000 with VIII degrees fortification and none of them and their nonstructural components were damaged in Wenchuan earthquake in 2008. However, many nonstructural components were damaged in this earthquake. The seismic damages of nonstructural components included infill wall cracks or deformation or local collapse, fall off of suspended ceiling, uplift of floor, fall off of hanging equipment, glass shattered and so on. Unexpectedly, three large span structures in seismic intensity VIII were all damaged, one of which appeared structural node damage. The nonstructural components of large span structures damaged severely and noticeably, especially the great loss of equipment. Another difference from previous earthquakes, the nonstructural components of wooden structures sitting in hillside had heavier seismic damages than those beneath the slope in seismic intensity VI.
