A108.2 Masonry Shear Strength

Existing Building Code 2015 of Idaho > A1 Seismic Strengthening Provisions for Unreinforced Masonry Bearing Wall Buildings > A108 Design Strengths > A108.2 Masonry Shear Strength

JUMP TO FULL CODE CHAPTER

The unreinforced masonry shear strength, v_m, shall be determined for each masonry class from one of the following equations:

The unreinforced masonry shear strength, v_m, shall be determined by Equation A1-4 when the mortar shear strength has been determined by Section A106.3.3.1.

The mortar shear strength values, v_t, shall be determined in accordance with Section A106.3.3.
The unreinforced masonry shear, v_m, shall be determined by Equation A1-5 when tensile-splitting strength has been determined in accordance with Section A 106.3.3.2, Item 1 or 2.
When f'_m has been estimated by categorization of the units and mortar in accordance with Section 2105.1 of the International Building Code, the unreinforced masonry shear strength, v_m, shall not exceed 200 pounds per square inch (1380 kPa) or the lesser of the following:

For SI: 1 psi = 6.895 kPa

where:

v = 62.5 psi (430 kPa) for running bond masonry not grouted solid.

v = 100 psi (690 kPa) for running bond masonry grouted solid.

v = 25 psi (170 kPa) for stack bond grouted solid.
