灾后重建再生混凝土框架结构抗震性能和设计研究
|
摘要
在分析以往再生混凝土框架结构抗震性能的基础上进一步研究该结构的抗震性能,提出模拟地震动模型振动台试验方案。分析汶川地震震害,并以一个建于都江堰市的二层再生混凝土框架抗震示范房屋为例,对再生混凝土框架结构设计进行探讨,并提出针对再生混凝土框架的结构及非结构构件抗震设计建议。提供的振动台试验模型和振动台试验的设计思路对今后有关的试验具有一定的借鉴作用。
In this paper,past achievements in the seismic performance of frame structures with recycled aggregate concrete are carried forward and a shaking table model test program is put forward for further seismic research of this kind of structure.Based on the analysis of building damage caused by Great Wenchuan Earthquake the seismic design and the practical applications of frame structures with recycled aggregate concrete(RCA) are explored.Besides,a newly built two-story house of recycled concrete frame in Dujiangyan City is set as an example for discussing main points of the seismic design of both structural and non-structural elements in RCA frames.The conclusion is that the proposed mix proportion design method for recycled concrete with fine aggregate is feasible in the test.The method applied in model and test program design of this frame structures with recycled aggregate concrete will be helpful to other experimental studies.
