This document analytically investigates connections between precast concrete columns. Three types of column-to-column connections are modeled and analyzed: 1) a long bolt connection using bolts passing through end plates, 2) a welded steel bearing face connection, and 3) a reinforcing bar coupling connection. The long bolt connection is analyzed using finite element software and found to have a total deformation of 0.35476mm and normal stresses of 14.733MPa and -16.684MPa under monotonic loading, within permissible limits. The document also provides details on modeling the connections and material properties used in the analysis.
