多高层重木框架-混凝土核心筒混合结构抗震性能研究

摘要

传统民用木结构建筑受限于传统观念和对绿色建筑的保护,一直维持在三层及以下,而随着科学技术的发展和思想的开放,人们越来越多的接受木结构建筑,往高层发展是木结构发展的一个必然趋势.从宏观上分析中高层木结构的可行性,利用通用有限元软件ABAQUS建立木框架和木框架-混凝土核心筒有限元模型,通过弹塑性时程分析法,对比顶部最大位移、层间位移角、加速度放大值等,研究木混结构用于高层的可能性.弹塑性时程分析是评价建筑结构抗震性能最精确的分析方法.%Traditional civil wooden structure buildingsarerestricted to traditional concept and the protection of green building,and have been limited tothreefloors and below.With opening of thoughts anddevelopmentof science and technology,more and more people are apt to accept wooden structures,and development of highrise wooden structures is an inevitable trend.In this paper,macro analysis of the feasibility of senior wooden structures was conducted.The possibility of using wood-concrete hybrid structures to construct high-rise buildings was analyzed using general finite element software ABAQUS,wherethe largestroof displacement,interstorydrift angles,acceleration amplification values were compared through elasto-plastic time history analyses.Elasto-plastic time history analysis is the most accurate method to evaluate seismic performance of building structures.
