进行建筑结构层间变形特征分析时未建模分析特征,导致分析效果较差,为解决上述问题,本文对地震后建筑结构层间变形分布特征展开研究.利用建筑信息模型技术建立建筑结构三维模型;引入广义层间位移谱法,构建层间位移等公式,进行建筑结构层间变形特征分布分析.研究结果表明:不同加速度下,层间位移随着加速度增加而增大;1层楼时弯矩、剪力和层间位移角分别达到237 kN·m、210 kN和1/231 rad,呈现最大的变化.分析结果与实际相符,可以有效地分析层间变形特征.
Characteristic distribution of inter story deformation of building structure after earthquake
It is not modeling analysis characteristics lead to poor analysis effect in the analysis of interstory deformation characteristics of building structure.Therefore,the distribution characteristics of interstory deformation of building structure after earthquake are studied.It built structure 3D model is established by building information model technology.The generalized interstory displacement spectrum method is introduced to construct the interstory displacement formula and it realize the analysis of interstory deformation characteristic distribution of building structure.The results show that the interlayer displacement increases with the acceleration under different accelerations.The bending moment,shear force and interstory displacement angle of a one-story building reach 237 kN·m,210 kN and 1/231 rad,respectively,showing the biggest changes.The analysis results are in agreement with the practice and it can be used to analyze the interlayer deformation characteristics effectively.
