Since 1981, ADAPT-PT’s proven reliability and ease-of-use have made it the most widely used software for the design of post-tensioned slabs and beams worldwide. It is based on the Equivalent Frame Method of analysis and leads the user through a simple to follow, step-by-step modeling and design process. Its unmatched ability to speedily produce optimized designs and quantity take-offs in minutes have made it the tool of choice for design professionals seeking to complete their post-tensioned projects profitably and consistently on time.
ADAPT-PT is the industry standard stand-alone program for the design of beam frames, slabs and floor systems post-tensioned with either bonded, or unbonded tendons. For two-way floor systems the user can base the analysis on either the Equivalent Frame Method, or the Simple Frame Method. For the post-tensioning design, the user can select between the Effective Force method and the Variable Force (Tendon Selection) method . In the Variable Force method, the software computes and accounts for the tendons' friction and long-term stress losses along the length of the post-tensioned member.
ADAPT-PT can handles drop caps, drop panels, steps above and below, transverse beams and non-prismatic sections. Selfweight is calculated using actual dimensions and material properties. In addition to the post-tensioning amount and profile, the software reports the location and amount of the nonprestressed steel along the length of the structure for the strength and minimum requirements. The solution is presented in a clear and concise tabular form, as well as in graphical format.
Output options also include a graphical summary report of all important design data, ready for transfer to structural drawings and inclusion in structural calculations. The graphical summary includes:
- Elevation of the member with the post-tensioning tendons in place
- The post-tensioning profile, elevation of control points and PT-force/number of strands
- Location, length and number of nonprestressed bars required over the entire member length
- Outcome of the one-way or punching shear design
- Designer' comments
- DXF output
Flexibility in selection of cross-sectional geometry makes this software suitable for design of box girder bridges, and I-girders in addition to traditional building and parking structures. ADAPT-PT is fast, easy to master, and is the choice of production-oriented consulting engineers around the world.
