摘要
通过4种结构方案比较,研究了框架-核心筒结构外框柱距改变时,结构抗震性能的变化。计算结果表明,在结构混凝土用量基本不变的情况下,随着外框柱距的减小,框架-核心筒结构的侧向位移、层间位移角都在随之降低,相对于方案1,方案2～4结构顶点位移分别减小了5.48%、9.84%、13.37%,最大层间位移角分别减小了6.78%、11.80%、15.89%。总体来说,随着外框柱距的减小,结构的抗震性能略有提高。
This paper mainly focuses on the analysis of the change of seismic performance of the frame-core wall structure when the frame spacing changes through four models.The results show that with the decrease of frame spacing,the lateral displacement,story drift angle are decreased.Comparing to the model1,top displacement of the structure of model 2 to 4 were reduced by 5.48%,9.84%,13.37%,the maximum story drift are reduced by 6.78%,11.80%,15.89%.With the decrease of frame spacing,the seismic performance of the structure is slightly higher when the amount of concrete of the structure is constant.
