【摘要】 目前的国家标准乃至学术文献,建筑物震后的安全鉴定都是以专业人员的经验为基础的,不能做到快速客观。我们在文献[2]中建议通过对比结构震前与震后的基频进行初步判断,并通过若干小震和脉动的现场实验研究说明了方法的技术可能性与现场可操作性。本文追加了成都市武侯区某住宅小区在汶川地震中的轻微震害案例,具体展示了文献[2]方法揭示建筑结构"不可见"震害的能力。更多还原

【Abstract】 The safe identification of a building after a destructive earthquake described by the present national standard and academic dissertations are based on the personal experiences. So this work is not fully objective. The suggestions in the paper 2 listed in the reference on the safe identification of a building are to compare the differences of structural basic frequencies between the pre-earthquake and post-earthquake. In this paper we explain both feasibility and maneuverability of this method through the tested results in the site of a building in Chengdu City which is affected by the 2008 Wenchuan Earthquake. Our result shows that this method is useful.更多还原
