摘要
现代夯土建筑有别于传统夯土建筑,在夯筑材料选择、夯筑机具、夯筑工艺、结构构造措施等方面做了较多技术改良。为研究其抗震性能,制作了1/2缩尺、采用钢筋混凝土构造柱及现浇屋面的单层夯土房屋模型,并进行了振动台试验。试验结果表明,由于承重夯土墙体采用机械夯筑,加上合理有效的构造措施对其形成很好的约束与加强,现代夯土建筑的抗震性能得到大幅提升,在遭受相当于8度罕遇地震作用下,模型房屋仍然可以继续承载,而且表现出较好的变形能力。该结构体系迄今为止已在西部农村进行了多个试点,对各地农村建设具有一定参考价值。
Unlike traditional rammed earth buildings,modern rammed earth buildings have been improved in rammed earth materials,ramming equipment,ramming technology,structural measures and other aspects. One 1:2 scale model of this kind of building is designed and tested on the shaking table in order to study its seismic performance. The test results show that the seismic performance of modern rammed earth buildings are significantly improved as the mechanical ramming technology and reasonable structural measures form good constraints and enhancement to the buildings. When the very rarely occurred earthquake in region with intensity 8 is encountered,the model house can continue to carry loads and shows good deformation capacity. So far we had several pilot projects of this structure system in western rural areas. They can provide certain reference to the national rural construction.
