ADAPT-ABI is a general finite element program which performs 4D time-dependent analysis of concrete bridges and frames during and after the construction phase. ABI can investigate the effect of newly placed concrete, creep, shrinkage, and relaxation in prestressing over time, aging of concrete, and variation in temperature. Its excellent graphical interface can display moments, shears, stresses, and deformations for various stages of construction. The software can handle nonprestressed concrete, precast, cast-in-place, pre-tensioned or post-tensioned frames. The software is intended for incrementally constructed bridges and frames; retrofit of concrete frames where new concrete is added, new members are added or existing members are modified; and demolition (reverse construction) of frames. Other applications include composite construction and cable-stay structures. The basic module of the software (ADAPT-ABI Basic) is self-contained and complete. Other modules enhance the capabilities of the basic program.
Wide Range of Bridge Design Applications
Quickly 3D model and analyze a variety of bridge types including precast girder, balanced cantilever, incrementally launched, cable stayed, box girder and many more.
Intuitive Model and Load Creation
Easily create and make changes to complex bridge geometry using graphical input or by inserting a dxf file. Generate loading including automatic moving loads with multiple travel paths according to predefined libraries.
Comprehensive Analysis and Results
Utilize finite element analysis to evaluate internal forces, stresses and deflection while also completing design code checks incorporating creep, shrinkage, relaxation of prestressing steel, aging of concrete and temperature effects.
