MASS™

MASS™ Modules

Quick and easy to learn.

MASS™ analyzes and designs masonry beams, shear walls and out-of-plane walls in accordance with the Design of Masonry Structures Standard CSA S304.1-04. Each module is set up in a similar manner. As a result learning to use MASS™ is quick and easy.

beam module

Beam Module


The beam module designs single-­wythe beams composed of semi­‐solid or hollow concrete block, as well as hollow brick. In addition, MASS™ Version 1.1 also models double-­wythe beams composed of solid brick units with a cavity in the middle. The beam module performs engineering calculations to design for the moment, deflection, shear (which may include the addition of stirrups), and bearing.

wall module

Wall Module


The wall module designs single-­wythe concrete block masonry walls. For walls, MASS™ Version 1.1 supports the following block types: hollow, semi-­solid, and solid block, which can be laid using a running bond or stack pattern arrangement. The wall module performs engineering calculations to design for the axial load, moment (including slenderness effects) and deflection (including secondary effects), and shear.

shear wall module

Shear Wall Module


The shear wall module designs single-­wythe concrete block masonry shear walls. For shear walls, MASS™ Version 1.1 supports the following block types: hollow, semi­‐solid, and solid block, which can be laid using a running bond or stack pattern arrangement. The shear wall module performs engineering calculations to design for the axial load, moment and deflection, and shear.
