Procedure 5-4 Design of Support Blocks

Often times, when beams are supported on a support ring, the beam is supported by, or reinforced with a support block(s). This procedure shows how to design the support blocks and attachment welds for the various load cases. There are two types of support blocks used. 

Type 1 Support blocks are welded integral with the web of the beam to expand the bearing area as well as reinforce the web in the area of local load. This type is used primarily with T-Type beams but could also be used with a built-up I beam. 

Type 2 This type is used with sohd beams where the top of the beam is located level with the top of the support ring to create a uniform support plane. The support block, also called a support plate, is welded to the top of the beam and cantilevers beyond the end of the beam to support the load.
