对交叉基础交叉处基础底面尺寸的修正

在计算墙下条形基础、柱下交梁基础时,对基础的宽度计算一般采用b=F/f-γ0d,此计算公式对交叉点外的基础宽度是可取的,但对交叉点处交叉的尺寸的计算因存在荷载的变化,对交叉点处基础宽度的计算存在着误差,从而影响了计算精度,对建筑物存在着安全隐患。为此,对交叉点处基础宽度在考虑荷载变化、重叠的情况下,对交叉点处基础宽度进行修正。

Amendments For The Size of the Bottom Base at the Intersection of Cross-Base

When we calculate the strip base beneath th e wall and the cross base beneath the column, we generally use the formula: b =F/f-r*d to calculate the width of base, which is suitable for the base width ou tside the intersection. But for variety loadings in calculating the size of the overlapping parts at the intersection, so there are some errors in the calculati on of the width at the intersection of the base, which affect the precision of t he calculation and create some hidden dangers for the safety of buildings. In th is passage, considering the situation of variety loadings and overlapping loadin gs, we make some amendments for the width of base at the intersection.
