Web3.2.2.1 Compressive strength of masonry The compressive strength of masonry depends on the compressive strength of units and mortar. The following equation (1) is recommended for the determination of the compres-sive strength. f K f f m b mo (f b and f m represent mean values) (1) WebMar 16, 2005 · Other much earlier references show a bearing ranging from 100 psi to 400 psi depending on brick compressive strength and mortar type. At 100 psi, the bearing plates will be unmanagable. The minimum required f'm is 1500 psi. 0.25 of that is 375 psi. That might seem pretty high but clay masonry brick are very very hard.
