Masonry Shear Wall
A precise tool.
What is the Masonry Shear Wall & How does it work?
Masonry shear walls act as vertical cantilevers that resist lateral forces through shear and flexure. The wallβs capacity depends on its geometry, the compressive strength of the masonry units, and the quality of the mortar joints. Engineers typically model the wall as a rectangular panel and evaluate its shear resistance using empirical coefficients derived from test data.
Design of a shear wall begins with defining the wallβs dimensions β length, thickness, and height β and selecting a target safety factor. The masonry compressive strength (f’m) and the shear coefficient (C) capture material behavior, while the safety factor (Ξ³) accounts for uncertainties in loading and construction quality. These parameters are combined in a simplified capacity equation that provides a quick check before detailed finiteβelement analysis.
The governing equation for the nominal shear capacity (Vn) of a masonry shear wall is expressed as:
V_{n}=C\sqrt{f’_{m}}\,t\,h
C = shear coefficient (typical 0.6), f’_{m} = masonry compressive strength (MPa), t = wall thickness (m), h = wall height (m)
