足尺木结构房屋振动台试验及数值模拟研究
|
摘要
为进一步了解木结构房屋的动力特性和抗震性能,对一个单层、足尺的木结构房屋进行多种工况的振动台试验研究和分析。试验中考虑传统木结构房屋的建造方式和构造特点,变化结构的平面布置和连接方式,分别研究它们在不同地震和烈度下的动力反应和抗震性能,以及结构的破坏形式和破坏机理。还结合有限元方法,对木结构房屋的动力计算方法进行研究和数值模拟,并与试验结果进行对比。研究成果对于了解传统木结构体系的动力特性与抗震性能具有重要的意义,为该结构体系的设计、加固与修缮提供相关依据和参考。
A series of shaking table tests for full size one-story wooden houses were carried out to further understand its dynamic characteristics and seismic performances.Different structure designs according to the construction methods and structural features of wooden houses were considered to investigate their dynamic response,seismic performance and failure mechanism synthetically under different levels of earthquakes.The dynamic calculation method using FEM for wooden houses was also discussed,and the numerical simulations were performed to compare with the shaking table test results.
