ABI 5.0 upgrade for free!
ADAPT-ABI Version 4.xx 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 fifteen years, and has provided the foundation for
analysis of many notable bridges.
ADAPT-ABI capabilities can be enhanced with the following modules:
·
ADAPT-Gen
·
ADAPT-Moving Load
·
ADAPT-Elongation
Complete analysis of the construction phase and in-service
performance, including safety checks for:
·
Balanced
cantilever bridges (Cast-in-place or Precast)
·
Incrementally launched bridges
·
Span-by-span bridges
·
Precast-prestressed girder bridges with field splicing and topping
slab
·
Box
girder bridges
·
Bridge
rehabilitation with external post-tensioning
·
Full
analysis, from casting date to 30 years and longer in-service,
including moving load generation, code combinations,
enveloping, construction loads, creep, shrinkage, relaxation
of the prestressing steel, aging of the concrete, and
temperature effects.

Product Details
ADAPT-ABI is a general finite element program which performs
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.
These are:
ADAPT-Gen Module
ADAPT-Gen enables the user to (i) break the structure into spans and
columns; (ii) display and tabulate the solution in a
span-and-column format; (iii) include automatic pattern
loading; and (iv) combine different loading conditions and
compile envelopes of load cases. Other features are directed
toward making the software an effective production tool.
ADAPT-Moving Load Module
The moving load module is developed primarily for bridge construction.
Using the software's library of the most common
truck or train loads, or a user-defined library, the program
automatically moves the loading along a user-defined path and
generates an envelope of sectional actions for combination with other
loading. The moving load module of ABI is
general and comprehensive. It is designed to cover all
foreseeable conditions in bridge design.

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.
