Problem Assignment - Vertical Load Capacity of URM Walls
The unreinforced, double-wythe brick wall shown below is constructed of bricks with a flat-wise compressive strength of 6000 psi that are laid in Type S mortar (made with masonry cement). No prisms are tested. Cores in the bricks have an area less than 25% of the gross area of the units. Grout is placed between the wythes to bond the wall together so that it acts compositely.
1. For the unreinforced masonry wall shown below, determine the maximum load per foot per the 2016 TMS 402 requirements that can be applied at an eccentricity equal to:
(a) 0.00"
(b) 1.50"
(c) 3.00"
2. Determine the maximum vertical force per foot that can be applied to the wall if the tensile strength is assumed to be equal to zero. Assume that the maximum compressive stress is limited to the value set by the 2016 TMS 402 for allowable axial compressive stress.
