摘要:
2019年6月17日22时55分在四川宜宾市长宁县发生了Ms6.0级地震,之后截至7月4日,又在长宁县和珙县范围内发生了4次Ms5.0级以上地震。珙县中学距离本次地震震中约20 km,学校内设有强震台站,记录到了本次地震的地震动数据,地震动峰值地面加速度达0.60 g。本次地震造成了珙县中学教学楼的较严重破坏。文中详细介绍了珙县中学教学楼的震害情况,对珙县中学教学楼进行了多个测点的脉动测试,结合珙县中学强震台的加速度记录特征和结构的自振特性,初步分析了教学楼不同类型构件的破坏原因。该栋结构的地震响应可作为一足尺振动台试验案例,对同类结构的抗震性能评估具有一定的参考价值。
Abstract:
An Ms 6.0 earthquake stroke Changning County on 22:55 June 17th, 2019. Another 4 earthquake with magnitude lager than Ms 5.0 took place at nearby areas before July 4th. A strong motion recording device used to monitor the earthquakes is set at Gong County middle school, which is about 20 km away from the epicenter. Acceleration histories with PGA at 0.6 g is recorded and related ground motions are given in this paper. The teaching building in this middle school experienced damage, especially the nonstructural components. To better understand the structural properties, Natural vibration tests is conducted, and related results are presented.
