摘要:
2017年5月11日新疆塔什库尔干5.5级地震给震区建筑结构造成了不同程度破坏。选择震区钢筋混凝土(RC)框架结构、砖混结构以及土石木结构等3类典型建筑结构,介绍了各类建筑结构地震破坏特点,分析了震害特征与破坏机理。结果表明:RC框架结构在地震中表现出了优异的抗震性能,即使在震中区,破坏也仅仅表现为非结构性破坏,如填充墙开裂和吊顶脱落等;砖混结构绝大多数抗震性能优良,仅震中区的少数建筑物发生了承重墙墙体开裂情况;土石木结构房屋抗震性能最差,地震破坏最为严重,是导致该次地震人员伤亡主要原因。建议地震高烈度设防区房屋建筑应采用抗震性能较好的RC框架结构和砖混结构,而抗震性能差的土石木建筑房屋应尽量避免继续建设和使用。结果可供类似地区房屋建设和建筑结构抗震设计等工作参考。
Abstract:
Some buildings were damaged in Xinjiang Tashkurgan M5.5 Earthquake. The seismic damage phenomena and mechanism were investigated and analyzed for reinforced concrete (RC) buildings, brick concrete buildings and adobe stone buildings in this paper. The results showed that the RC frames performed good seismic capacity, and only the non-structural members of a few buildings were damaged. For example, the infill walls were cracked, and the ceiling systems were fallen. The masonry buildings also performed good seismic capacity, and only the bearing walls of a few buildings were cracked in the epicentral area. However, the adobe stone buildings were damaged seriously in the epicentral area, and the earthquake casualty were mainly caused by the collapse of the adobe stone buildings. It is recommended that the RC frames and the masonry buildings should be considered and built, but the adobe stone buildings should be avoided to be constructed any more in high intensity seismic regions. The investigation results provide a reference for the seismic design and construction of buildings in similar areas.
