ADAPT ABI : Bridge Design Software with 4D Construction Sequencing and Time-Dependency
ADAPT-ABI 2019 is a special-purpose program developed for the design and analysis of prestressed concrete bridges built either segmentally or conventionally. It provides information for geometry and stress control during construction, as well as design values for service load. ADAPT-ABI has been serving bridge design engineers worldwide for over twenty years, and has provided the foundation for analysis of many notable bridges.
Featuring a 3D modeling interface, and intuitive 4D construction sequencing capabilities, this next generation ADAPT-ABI delivers unparalleled modeling ease and speed.
Packed with a full range of powerful modeling and analysis capabilities, ADAPT-ABI is a practical tool bridge engineers can use to rapidly evaluate design options and shorten project delivery times.
ADAPT-ABI extension modules included with every license:
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.
ADAPT-Moving Load Module
ADAPT- Elongation Module (includes friction and stress loss)
At the completion of an ADAPT-ABI computer run, and without any additional input data, this module calculates the elongation of each of the tendons at stressing and the associated stress losses. The stress losses include the effects of friction and the time-dependent parameters of creep, shrinkage, and relaxation in prestressing.
