#CONCRETE MASONRY UNIT CALCULATOR CODE#
Weights listed in the tables are based on the following assumptions.
Because of the small core size and resulting difficulty in consolidating grout, these units are rarely grouted. (102-mm) concrete masonry walls are not provided. Tables 1 through 8 list concrete masonry wall weights for 4 to 16 inch (102 to 406 mm) thick single wythe walls. See TEK 6-1A, R-Values of Multi-Wythe Concrete Masonry Walls, and TEK 6-2A, R-Values for Single Wythe Concrete Masonry Walls (refs.
Dead loads to resist uplift and overturning for high wind resistance.Īdditional wall properties are also impacted by wall weight, although estimates of these properties are based on concrete density or aggregate type, rather than directly on wall weight.Gravity loads (wall dead loads) on structural members such as lintels and foundations.See TEK 6-16A, Heat Capacity (HC) Values for Concrete Masonry Walls (ref. Heat capacity, an indication of thermal storage capacity, with heavier walls providing higher heat capacities and potentially better energy performance.See TEK 14-12B, Seismic Design Forces on Concrete Masonry Buildings (ref. Seismic base shear force, with heavier walls resulting in higher base shear values.
See TEK 13-1B, Sound Transmission Class Ratings for Concrete Masonry Walls (ref. Sound transmission class (STC) ratings, with heavier walls providing higher STC ratings and hence better sound insulation.Wall weights are used directly to calculate: Many of these attributes are measured quantitatively, and often vary directly with the weight of the concrete masonry wall. Concrete masonry walls provide a range of benefits, including structural integrity, fire and sound resistance, energy efficiency, insect resistance, durability and architectural interest.
