I need to temporarily support bridge beams at abutment. Length from footing varies from 3'+- to 8'+-, want to use segmental HS12x12x3/8 with a single 1x18x18 plate between segments. No more than 4 segments per column. Neoprene will be used top and bottom for rotation at longer columns and shear at shorter columns. The thermal movement is .43" the load is 150k+-. I'm thinking friction coef. of 0.4 Is there any reason to weld the segments?
