[提要] 平板式筏基為無梁體系，傳力簡捷，整體剛度好，施工速度快，是框架結構常用的基礎形式。對等代框架法和經驗系數(shù)法進行分析比較后，提出了適用于平板式筏基的等代梁彎矩系數(shù)法，并結合新規(guī)范對板的沖切計算、受剪計算、彎矩及配筋計算推導了較實用的簡化公式和條件式，編制了計算表。
[關鍵詞] 平板式筏基 等代梁彎矩系數(shù)法 簡化公式 計算表Slab-foundation is one of popular styles of foundation in frames,which features slab system without girder, specific mechanics, excellent structural stiffness and easiness in construction. Based on analysis and comparison between the method of equivalent frames and the method of practical experience factor design,a new design method of moment factor in equivalent beam for slab foundation is obtained. Combined with the new codes, the formulas of simplified calculation and requirement, including the calculation of punching, shear, flexural and design for reinforcement, are presented for practice. The calculation charts for design are also given.
Keywords: slab-foundation; momeot factor; equivalent beam method; simplified calculation formulas; design
