摘要:
2021年5月21日云南漾濞发生6.4级地震,成为继2014年6.5级鲁甸地震和6.6级景谷地震之后云南省内时隔7年的又一次震级大于6级的破坏性地震。漾濞地震虽然与鲁甸地震在震级、震源深度和震源机制等方面均较相似,但漾濞地震震中附近的地面运动强度远不及鲁甸地震,且漾濞县的抗震设防烈度远高于鲁甸;相应地,漾濞地震对抗震设防建筑造成的破坏也远轻于后者。本文首先通过比较这三次地震震中附近的强震记录的反应谱,并结合公共建筑的震后应急评估结果,说明漾濞地震和鲁甸地震中公共建筑破坏程度的显著差异。进而以位于漾濞县城的两栋钢筋混凝土公共建筑为例,介绍此次地震中砌体填充墙和吊顶等典型非结构构件的震害。
Abstract:
The M6.4 Yangbi earthquake on May 21, 2021 was another devastating earthquake (M>6) in Yunan province after seven years since the 2014 M6.5 Ludian earthquake and M6.6 Jinggu earthquake. Despite their similar magnitudes, focal depths and source mechanisms, the Yangbi and Ludian earthquakes produced ground motions near the epicenters of very different intensities and frequency contents. In addition, the seismic design intensity for buildings in Yangbi is much higher than that in Ludian. Accordingly, the seismic damages to the buildings near their epicenters were significantly different. This is made clear by comparing the response spectra of the ground motion records near the epicenters of these earthquakes and summarizing the results of the emergency inspection of public buildings immediately after the Yangbi earthquake. In addition to the insignificant structural damage, the nonstructural damage to the public buildings in the Yangbi earthquake is highlighted in the rest of the paper. The observed damage to typical nonstructural components such as masonry infills and suspended ceilings in two public buildings of reinforced concrete frame structures is introduced.
