高层钢筋混凝土结构竖向变形差问题的探讨

根据竖向荷载加载和徐变的探讨,阐述了结构竖向变形差对内力重分布的影响,分析了不同竖向荷载加载方式的区别、适用范围和注意事项。同时分析了徐变变形与受力变形之间的差异及对结构和非结构构件的影响。提出了受力计算、结构选型、构造措施和材料选用等因素综合考虑,是解决竖向变形差问题的对策。

DISCUSSION ON VERTICAL DEFORMATION DIFFERENCE OF TALL R.C. BUILDINGS

According to a discussion on the vertical loading and creep,it was elaborated the effect of vertical deformation difference of a structure on internal force redistribution,it was analysed the differences between the different vertical loadings,applicable scope and matters needing attention. It was analyzed the differences between the creep deformation and forced-deformation and thier impact on structural and non-structural components. The combined consideration on the force,calculation the structure of selection,material selection and structural measures was the countermeasure to solve the vertical deformations difference.
