黄土地区农村民房生土建筑墙体材料抗震性能试验研究

Study on Seismic Resistance Performance of Wall Material Used in Rural Raw-soil Buildings in Loess Area

摘要:

对西北黄土地区农村民房生土建筑墙体材料的主要类型进行了物理力学性能和动力特性的试验研究,给出了黄土和黄土状亚粘土的夯筑墙、土坯等样品的抗压、抗折、抗剪强度以及动弹性模量和阻尼比等参数,对比分析不同生土建筑墙体材料和成型方式的强度和抗震性能.

Abstract:

The testing on the physical mechanical properties and dynamic characteristics of wall materials for main types of the rural row-soil building in loess area of northwestern China is performed. The compressive strengths,rupture strengths, shear strengths, dynamic elastic modulus and damping ratios for the ramming soil wall and adobe wall,which made from loess and loessal lain,are obtained from the tests. The strengths and seismic resistance performance of different materials and different forming typies for row-soil wall are analyzed and comparied,too.
