Concise Beam Version 4

Concise Beam is an easy to use program for the design of precast concrete beams. Concise Beam will perform a load analysis and design checks in accordance with the latest edition of ACI 318, CSA A23.3 & S6, AS3600, or NZ3101.1. Key code parameters can be customized to simulate other design codes. The beam can be conventionally reinforced, partially or fully pretensioned. It can model any cross-sectional shape and will allow the cross-section to vary prismatically (step-wise) over the length of the beam. A graphical editor allows the user to describe any cross-section, including voids.

Concise Beam works in two-dimensions using simple beam theory (ACI B-region) but will also account for torsion along the beam. Concise Beam is NOT able to perform any analysis or design checks required for disturbed regions (ACI D-region) such as at sudden changes in section, large openings, notches, or dapped ends. The user can work in metric or U.S. Customary (Imperial) units, with a variety of individual units (i.e. mm, cm, m), and switch back and forth at will. Libraries of industry standard cross-sections and materials are provided with Concise Beam. The standard libraries can be modified, extended and customized by the user.
