# Tag: Strength Approach Minimum and Maximum Reinforcement Ratios for Flexural Design of Masonry Shear Walls by the Strength Approach

Minimum Flexural Reinforcement by 2008 MSJC Code The 2008 MSJC Code has no global requirements for minimum flexural reinforcement for shear walls. Maximum Flexural Reinforcement by 2008 MSJC Code The 2008 MSJC Code has a maximum reinforcement requirement (Sec. 3.3.3.5) that is intended to ensure ductile behavior over a range of axial loads. As compressive axial load increases, the maximum

# Tag: Strength Approach Example of Interaction Diagram by the Strength Approach (Spreadsheet Calculation)

Construct the moment-axial force interaction diagram by the strength approach for a nominal 8-in. CMU wall, fully grouted, with fm′ = 1500 lb/in.2 and reinforcement consisting of #5 bars at 48 in., placed in the center of the wall. The effective width of the wall is 6t, or 48 in. The spreadsheet and corresponding interaction diagram are shown in Fig.

# Tag: Strength Approach Example of Moment-Axial Force Interaction Diagram by the Strength Approach (Hand Calculation)

Construct the moment-axial force interaction diagram by the strength approach for a nominal 8-in. CMU wall, fully grouted, with fm′ = 1500 lb/in.2 and reinforcement consisting of #5 bars at 48 in., placed in the center of the wall. Compute the interaction diagram per foot of wall length. For the case of a wall with reinforcement at mid-depth, the reference
