一个未完工的二层预制混凝土结构物的抗震测试

       一个未完工的二层预制混凝土结构物的抗震测试
6 ]; d6 _" p; }+ T- c这篇文章是关于地震和预制混凝土建筑物设计的试验性的研究。墨西哥市里一个带有双重系统和代表了一个停车场结构的未完工的两层的预制混凝土建筑物被调查研究。这个结构物在实验室里用模拟地震荷载测试，结果失败了。在一些梁和柱的接头处，粱底部的纵筋由于尺寸的限制不能屈服。这项研究所强调的是提高所测试结构物的可观察的综合性能。这种性能表现为所测试结构物的墙控制传力途径而且能显著地减少预制结构所要求的侧向变形。源自于这项研究的预制混凝土结构抗震设计标准和规范细节被讨论。这项研究的最终结果是能更好地理解这种类型的建筑物的已得知的性能。
       Tests on a Half-Scale Two-Story Seismic-Resisting Precast Concrete Building
* G% @+ i( W+ [9 Y- Y% p: }% }/ z- f5 }This paper describes experimental studies on the seismic behavior and design of precast concrete buildings. A half-scale two-story precast concrete building incorporating a dual system and representing a parking structure in Mexico City was investigated. The structure was tested up to failure in a laboratory under simulated seismic loading. In some of the beam-to-column joints, the bottom longitudinal bars of the beam were purposely undeveloped due to dimensional constraints.
