Design of a Beam Bearing Plate per AISC Specification

June 8, 2017 Abdul Siraj, P.E.

In this post, I will discuss the tenth example in our steel design course covering the analysis and design of flexural beam members. The goal of this steel design example is to design a bearing plate for a simply supported beam in order to distribute the reactions at the supports. We are using the 13th edition of the AISC Steel Construction Manual.


The problem statement states,


A W21 x 68 beam has a span length of 16 feet (center to center of supports) and is supported on reinforced concrete walls with f’c = 4 ksi. The dead load is 5 kips/ft including beam weight and live load is 5 kips/ft. Design a bearing plate to distribute the reaction at the supports. The yield strength of the beam is 50 ksi and the yield strength of the plate is 36 ksi.
