Choosing between ADAPT-Builder and ADAPT-PT/RC?

Whatever your concrete design needs are, there is an ADAPT software for you. Schedule a software tour today and let us show you around!

ADAPT-Builder is a full 3D Finite Element Modeling, Analysis, and Design software for conventionally reinforced and post-tensioned concrete buildings, including foundations and elevated slabs. ADAPT-Builder includes the ability to model natively or to quickly transform an imported DXF/DWG file to modeled elements. The modeling features allow for easy creation of complex geometries including stepped slabs, sloped columns, elevator pits, ramps and more. ADAPT-Builder's Colorize feature allows you to colorize components based on properties for easy verification of input properties for the modeled components.

  • Automatic Connection of Supports
  • Ramp Modeling
  • Stepped Slabs
  • Properties Grid
  • Sloped Columns
  • Wall Openings
  • Post-Tensioning

ADAPT-Builder allows the application of gravity and lateral loading, including tools to quickly apply these loads to the model. Along with the ability to include these loads in a FEM analysis, Builder also includes the option to run a Tributary Load Takedown using our patented Tributary Load Manager.

  • Load Combination Generator
  • Auto Calculation of Long-Term Factors
  • Live Load Patterning
  • Live Load Reduction
  • Import from XLS

Lateral Load Generators

Automatically generate and apply wind and seismic loads per ASCE codes.

Load Combinations

Manually or automatically generate code-based or user-defined combinations.

Tributary Load Takedown

Quickly generate results using our load takedown based on tributary areas

ADAPT-Builder contains the various tools for performing a full 3D Finite Element Analysis and viewing the analysis results for a single-level or the entire model at once. Create and modify the finite element mesh, manage stored reactions, assign stiffness modifiers, and more. In addition ADAPT-Builder can analyze models for P-Delta, Vibration, and Cracked Deflections.

  • Vibration Analysis
  • Single & Multi-level Analysis
  • P-delta Analysis
  • Cracked Deflection
  • Advanced Meshing tools.

Floor Vibrations

Automatic calculation of floor accelerations and frequencies using slab stiffness

Cracked Deflections

Deflection calculations consider loss of bending stiffness due to cracking of floors and beams

Single & Multi-Level

Perform analysis on a single floor or an entire building at once within a single model

ADAPT-Builder includes the ability to design and investigate conventionally reinforced, post-tensioned, or hybrid two-way and one-way slabs, beams, foundations, as well as conventionally reinforced columns and walls. Punching shear design can also be performed including both drop caps and drop panels. Slab design is performed utilizing Support Lines and Design Sections which allow users to view various results including stresses, demands, and capacities to aid in the design or investigation of these elements. Use the analysis results from the column and wall design features to fully design and code check columns and concrete shear walls, including wall cores. Walls can be designed with or without special boundary elements for seismic lateral resisting systems.

  • Slab Design
  • Foundation Design
  • Column Design
  • Wall Design
  • Punching Shear Design
  • Beam Design

ADAPT-Builder includes the ability to review analysis results through tabular and graphical reports as well as graphically in the model space. Generate fully compiled reports including default tabular and graphical reports, as well as screenshots of graphical results. The Colorize feature can also be used to view model results in an easily interpreted view, such as applied loading and column design results. Detailed calculation reports are also available for minimum reinforcement, column design, and wall design.

Graphical Results View

Directly view analysis and design results graphically in the model space for easy engineering decisions.

Model Colorization

Colorize components by property for easy model verification. Colorize applied loads based on their magnitudes.

Report Compiler

Select tabular, graphical reports, and screenshots to be generated as a compiled report.

ADAPT-Builder includes many options for integration with other programs and between ADAPT-Builder models. Share level definitions, component geometry, material properties, loading, etc. between ADAPT-Builder models using the INP file. Integrate full Revit models to and from ADAPT-Builder. Quickly create geometry by importing a DWG/DXF file. Import loads into ADAPT-Builder from an Excel file or directly import RISA-3D reactions.

  • RISA-3D Integration
  • Revit Integration
  • DXF/DWG Import
