Correction Factor for Rectangle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Correction Factor Nq = 1+(Width of Footing/Length of Footing)*(tan(Angle of Internal Friction))
N _q = 1+(B/L)*(tan(φ))
This formula uses 1 Functions, 4 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)

Variables Used

Correction Factor Nq - Correction Factor Nq is the function of angle of internal friction Ø.
Width of Footing - (Measured in Meter) - Width of Footing is the shorter dimension of the footing.
Length of Footing - (Measured in Meter) - Length of Footing is the length of the larger dimension of the footing.
Angle of Internal Friction - (Measured in Radian) - Angle of Internal Friction is the angle measured between the normal force and resultant force.

STEP 1: Convert Input(s) to Base Unit

Width of Footing: 2 Meter --> 2 Meter No Conversion Required
Length of Footing: 4 Meter --> 4 Meter No Conversion Required
