配筋砌块剪力墙结构的内力与配筋计算方法

Analysis of internal force and reinforcement of reinforced concrete masonry shear wall structure

如何高效、准确地对配筋混凝土砌块砌体剪力墙这一新型结构体系进行内力分析与配筋计算成为目前受关注的问题,也是其推广、发展的关键环节.基于该结构体系的受力性能特点,提出采用SATWE结构计算软件与EXCEL编程手段相结合方法分析结构内力并计算墙体配筋.在墙体厚度录入、计算参数的设置等方面进行了不同方法的对比.结果表明:直接输入砌块墙体厚度,并对连梁刚度折减系数给予适当提高后,可使SATWE内力计算结果更好地反映配筋砌块剪力墙结构实际情况;将SATWE输出文件转化为电子数据表格,利用EXCEL软件编制墙肢和连梁的配筋程序,简化了墙体配筋的计算工作量.在数十栋中高层配筋砌块剪力墙结构中得到应用与验证.

To obtain the internal force analysis and design of the reinforced concrete masonry shear wall structure high - efficiently and accurately, SATWE and EXCEL were applied to analyze the internal force and calculate the reinforcement of walls. The ways of inputting the thickness of walls and the value of the rigidity reduction factor of coupling beam were compared. With the direct inputting of the wall thickness without modifying and the proper increasing of the rigidity reduction factor of coupling beam, the internal force calculated by SATWE agrees well with the characteristic of reinforced concrete masonry shear wall structure. EXCEL programming was provided to calculate the reinforced steel bars of walls for reducing the workload..The above - mentioned method has been verified and widely used in the design of decades of reinforced concrete masonry shear wall structure.
