【摘要】：从降低基础底板厚度以达到节约混凝土和降低基础本体费用的角度出发,阐述和分析了中、美、英三国规范在板式基础冲切承载力计算方面的异同。通过对比发现:冲切承载力计算时,相比中标及美标,英标额外考虑了底板纵筋配筋率的影响;各计算参数相同时,按照美标计算的基础抗冲切承载力最大,中标及英标趋于保守;基础底板配筋率和混凝土强度等级是影响英标冲切承载力分界点的主要参数;对冲切计算起控制作用的基础,按照美标设计时可以做到用料最省。
[Abstract]:From the point of view of reducing the thickness of the foundation floor to save concrete and reduce the cost of the foundation body, this paper expounds and analyzes the beauty of the foundation. The differences and similarities in the calculation of punching capacity of plate foundation are found in the codes of the three countries. It is found that when calculating the punching capacity, compared with the winning bid and the American standard, the British standard takes into account the influence of the reinforcement ratio of the longitudinal reinforcement on the bottom plate; When the calculation parameters are the same, the punching shear capacity of the foundation calculated according to the American standard is the largest, and the winning bid and the British standard tend to be conservative. The reinforcement ratio of foundation slab and the grade of concrete strength are the main parameters that affect the dividing point of punching shear capacity of British standard. Hedge-cutting calculation plays a controlling role, according to the U. S. standard design can achieve the most economical material.
