鲁甸地震村镇建筑震害调查与分析
|
摘要
"8.03"云南鲁甸地震对当地村镇建筑造成大范围严重破坏。本文根据对鲁甸、会泽等地不同烈度区域的现场调查,分别对村镇公共建筑和自建农房的典型震害进行了客观的描述和分析。调查结果表明:经正规设计、施工质量有保证的村镇建筑在此次地震中基本表现良好;大量传统夯土农房由于材料性能低下,且缺乏任何抗震构造措施,损毁严重,总体形成"中震大灾"。文中对如何提高自建农房的抗震性能提出了一些建议。
The "8. 03"Ludian earthquake resulted in wide and serious damage to local rural buildings. Based on the field investigation,under different seismic intensities,in Ludian and Huize,the typical damage to rural public buildings and rural residential buildings are described and analized. Damage investigation shows that rural buildings with engineering design and construction quality certification have high seismic performance. A large number of traditional rammed-earth houses were seriously damaged,because of the poor material properties and lack of seismic design details. In general,the earthquake was moderate,but it brought great disaster to the society. Some suggestions to improve the seismic performance of residential buildings are provided.
