【摘要】 采用6种不同的有限元分析模型对密肋复合墙板结构中复合墙板与边框架以及填充砌块与混凝土框格协同工作方式进行了模拟.通过将采用不同计算模型的计算结果与试验结果的比较分析,提出了“刚架-平面子结构"计算模型.通过对填充砌块弹性模量不同取值的计算和数理统计结果的分析,提出了对填充砌块弹性模量进行统一修正以对该计算模型进行修正的方法.计算分析与试验结果对比表明:修正后的“刚架-平面子结构"计算模型计算方便、可靠,是进行密肋复合墙板结构弹性受力分析的理想计算模型.更多还原

【Abstract】 The interactive load-bearing properties between the multi-ribbed compound wall-slab and the frame,and also between in-filled blocks and surrounding frame grids are simulated by using six different Finite Element analysis models.The rigid frame-plane compound substructure(RFCS) analytical model is proposed by comparing the computing result of these models with the test results.The method for revising the analytical model by amending elastic modules of in-filled block is introduced,as a result of the computing and mathematical statistics of different elastic modules value used.The result of comparison between theoretical and experiment results express that the revised RFCS analytical model is convenient and reliable for computing,and is an ideal model for the analysis of elastic load-bearing properties of multi-ribbed compound wall-slab structure.更多还原
