ADAPT-RC is software for the Design, Analysis, and Investigation of Reinforced (Nonprestressed) Concrete Beams, Slabs and Floor Systems.  An industry standard and choice of consulting engineers requiring an easy-to-use, efficient, and reliable production tool. This software is based on the time proven Equivalent Frame Method (EFM) of analysis and features the following:

  • Complete modeling and design of reinforced concrete floor systems
    • Simple and continuous beams and beam frames
    • Multiple beam cross-section: T, L and I-section
    • One-way slabs
    • Two-way flat plates
    • Two-way flat slabs
    • Drop caps, drop panels, transverse beams, steps above and below the slab
    • One-way pan joist systems
    • One-way skip joist systems
    • Two-way joist systems
    • Waffle slabs
  • Investigation mode – analysis and capacity calculation of an existing floor
    • Gives the capacity of a floor system for a user-defined reinforcement distribution
    • Performs capacity/demand analysis for existing floor systems
    • Calculates deflection based on user specified loading and reinforcement
  • Advanced analysis options
    • Moment redistribution
    • Inclusion of lateral loads
    • Deflection calculation, including cracked section analysis
  • Comprehensive design capabilities

Product Details
ADAPT-RC is for the analysis and/or design of reinforced concrete beams, slabs and floor systems. It is based on a single story frame, featuring the Equivalent Frame modeling of the ACI code as an option. In its design mode, the program determines the deflection and reinforcement for a user defined geometry, material and loading. In its analysis mode, for a given floor geometry, loading and reinforcement, the software determines the capacity of the floor and compares it with the code stipulated demand. In both the design and the analysis modes, the deflections are calculated using cracked sections, with each span subdivided into 20 segments. ADAPT-RC is easy to use, yet thorough and rigorous in its formulation. Its graphical display gives a vivid account of moments, reinforcement and other parameters. ADAPT-RC handles both prismatic and non-prismatic spans, as well as supports with different boundary conditions. A solid model viewer allows the user to examine the input structure for a visual check on the accuracy of data entry. The primary application of the software is in building construction and parking structures.

ADAPT-RC is offered in two versions, a low cost version referred to as “Standard” and a “Plus” version. The two programs are identical except that the Standard version is limited to 5 pans and two cantilevers. The Plus version goes up to 20 spans and two cantilevers.

ADAPT-RC is a stand-alone program. But, when used together with ADAPT-Builder, it can receive input data generated graphically by the Builder. This feature of the program is discussed in greater detail under the heading ADAPT-Builder.
