How to Design Base Plates Used in Steel Structure ? | Civil Engineering

Suppose a column carries a factored load P at an eccentricity e. The moment due to the eccentricity = M = Pe. Alternatively if a column carries an axial load P and is subjected to a moment M we may consider as though the load P is at an eccentricity e given by- e = M/P . Let B be the width and L the length of the base plate (Fig. 7.72).
