【摘要】 剪力墙结构计算通常采用有限元方法、框架近似法和连续化方法 ,这些方法计算量大 .为此 ,探讨一种简单、适用的离散力法 .将结构经适当简化 ,取连梁中点的剪力作为基本变量 ,建立层间协调方程 ,从而确定层间内力和位移 .该方法可大大降低分析工作量 ,算例表明其计算精度与常用的连续化方法结果极其接近 ,表示该方法精度可靠 .文章进一步探讨了柔性地基情况下结构内力和侧向位移随地基刚度变化的规律 ,发现柔性地基假设结构的层间剪力较刚性地基假设结构的层间剪力小而侧移有所增大更多还原

【Abstract】 Finite element method,similar frame method or continuous method are used to calculate shear wall structures,but always with amonent of working,so a simple ,suitable DFM(discrete force method) is discussed. Presents the harmonize equation established with the shear force in middle of beam as based variable between adjacent floor, and then the in force and displacement determined between floors, and concludes that the flexible bases shear force is larger than the digited bases shear force,insteated of the displacement.更多还原
