Abstract. For the lower portion of some of its mechanically-laminated columns, Jack Walters & Sons Corporation has developed a steel-reinforced plastic (SRP) base. This SRP base is spliced to the upper, laminated-lumber portion of the column with a combination of truss plates, steel transfer plates and screws. This paper contains the results of a series of bending tests conducted on the plastic base-to-lumber splice region for nominal 5x6 and 5x10 inch columns. The bending strength and stiffness of the splice region is compared to those of the unspliced lumber region and the unspliced steel-reinforced plastic region.
