密肋壁板结构微观模型及非线性地震反应分析

THE MICRO-ANALYSIS MODEL AND NON-LINEAR EARTHQUAKE RESPONSE OF MULTI-RIBBED COMPOSITE SLAB STRUCTURE

密肋壁板结构由密肋复合墙板与隐形框架构成,密肋复合墙板的肋梁、肋柱和填充块是由两种不同的混凝土材料组成。采用梁单元与壳单元建立密肋壁板结构微观有限元分析模型,并对1/10比例振动台模型试验进行非线性地震反应分析。计算结果与试验吻合良好,表明所建立的有限元模型是可行的。

The multiribbed composite slab structure is constructed with multiribbed composite walls and latent frames.The ribbedbeams,ribbedcolumns and filled blocks of multiribbed composite wall are made of two different concrete materials.The microanalysis FEM model of the multiribbed composite slab structure is built up by beam elements and shell elements.Threedimension computational model was adopted in the nonlinear earthquake response of 1/10 model in shaking table test and its earthquake response was given.The calculated curves agree well with the experimental ones.The analysis shows that the FEM model is feasible
