结构设计有关问题探讨

Discussion about Structural Design Issues

本文对独立基础的剪跨比较小时的抗剪承载力的计算、地下室抗拔灌注桩裂缝宽度的复核、《装配式混凝土结构技术规程》JGJ 1-2014关于预制柱底和预制剪力墙水平接缝的受剪承载力的设计值公式、人工挖孔桩孔底采用荷载板试验结果的应用、无梁楼盖柱帽上翻时,柱上板带的配筋计算和高层建筑没有设置地下室,不满足《高规》的基础埋置深度的要求的处理方法等六个问题进行讨论,得出有利于工程设计中的应用的结果。

Six issues were discussed in this paper,and the results obtained is helpful to the application of engineering design. Six issues are as follows：The calculation of shear bearing capacity when the independent foundation of shear span ratio is relatively small. The review about the cracks width of uplift grouting pile in basement. ＂Technical specification for precast concrete structures＂（ JGJ 1- 2014） about design value formula of shear bearing capacity of precast column bottom and precast shear wall horizontal joints. The application of loading plate test results about the bottom of artificial dig- hole pile. The calculation of the column strip reinforcement when the column cap of floor without beam on the turn. High- rise buildings without the basement do not meet the requirements of foundation embedment depth in＂Technical specification for concrete structures of tall buildings＂.
