- If the depth of two column sections is equal, then the column splice is provided
- If M is the moment due to a couple in a bearing plate whose width is b and allowable bending stress is P, the thickness (t) of the bending plate of the column splice, is
- If M is the moment due to a couple in a bearing plate whose width is b and allowable bending stress is P, the thickness (t) of the bending plate of the column splice, is
- If the depth of the section of an upper column is smaller than the lower column
- If R is the reaction on the bearing plate, the minimum moment of. inertia of the bearing stiffener provided at the support of a plate girder of overall depth D, the maximum thickness of the compression flange T, carrying total load W, is
- A column splice is used to increase
- To keep the intensity of bearing pressure between the column base and concrete, compressive throughout the length of the column base, the ratio of the moment M to axial load P should be
- Under a concentrated load, bearing stress fb in a beam is given by (where b is the length of the bearing plate and h is the depth of the root of the fillet).
- Under a concentrated load, bearing stress fb in a beam is given by (where b is the length of the bearing plate and h is the depth of the root of the fillet).
- For the economical design of a combined footing to support two equal column loads, the projections of beams in lower tier are kept such that bending moment under column is equal to
