Then specify the number of vertical rows that occur at each bearing and the spacing between those rows. Specify the number of bolts in each vertical row at the bearing and the spacing within those vertical rows. Specify yield strength and modulus of elasticity of the steel plate(s). Number of shear planes affects the bolt bearing calculation. Number of steel plates input allows multiple of the defined individual steel plate. Specify the depth and thickness of one individual steel plate. Enter the value of E', as no further adjustment factors are applied to this value. Number of laminations input allows multiple of the defined individual wood lamination.ĭowel bearing strength of wood comes from NDS Table 12.3.3, which is provided for convenience with a click of the related help button.Į wood is the modulus of elasticity that will be used. Specify depth and thickness of one individual wood lamination. Finally, the specified bolts are checked for bearing in accordance with NDS requirements. The module then performs the load distribution to determine the percentage of load attributable to the wood member(s) and to the steel plate(s). It allows both ASD and LRFD, but for simplicity it assumes that the values are already factored appropriately and combined. The Flitch Plated Wood Beam module provides an efficient way to evaluate a simply-supported wood beam reinforced with one or more steel flitch plates. ![]()
