Info

Unreinforced load-bearing masonry buildings often contain perimeter bearing walls and interior bearing walls made of clay brick masonry (see Figure 2-37). In older construction, floor and roof framing consists of straight or diagonal lumber sheathing supported by wood joists, on posts and timbers. In more recent construction, floors consist of structural panel or plywood sheathing rather than lumber sheathing. The diaphragms are flexible relative to the walls. When they exist, ties between the walls and diaphragms consist of bent steel plates or government anchors embedded in the mortar joints and attached to framing. Foundations consist of brick or concrete spread footings. As a variation, some URM buildings have stiff diaphragms relative to the unreinforced masonry walls and interior framing. In older construction or large, multi-story buildings, diaphragms may consist of Structural deSign criteria Figure 2- rM2 reinforced masonry walls with stiff diaphragms 2-
Figure 2- urM load-bearing walls cast-in-place concrete. In regions of low seismicity, more recent construction consists of metal deck and concrete fill supported on steel framing. Unless sited in a seismic zone, reinforced masonry structures are not typically detailed to develop significant inelastic deformations and withstand significant load reversals. Unreinforced masonry structures are extremely brittle. As a point of reference, a reinforced masonry building with 8-inch thick reinforced CMU exterior walls is likely to suffer heavy damage in response to 500 pounds of TNT at a distance of 150 feet or less. An unreinforced masonry building with reinforced CMU pilasters will suffer heavy 2- 8 Structural deSign criteria
