ABT

2Bridge CAD is software intended for bridge engineering

applications. Present version of Bridge CADcontains

set of two cooperating with each other modules: ABT

for abutment structures and KXGfor foundation piles.

Work method

ABT generates *.dat files which user can

calculate in SOFiSTiK software and obtain

all necessary results to design bridge

abutment.

Structure types

12 types of abutment structure

shapes what covers 99% of design

cases

Structural model

2D slab

Beams

Springs

Loads

Abutment self loads

All ground effects

Traffic

All loads from deck

Analysis

Construction stages

All methods available in SOFiSTiK

Design codesAll codes available in SOFiSTiK

33Program Interface

ABT Interface leads user intuitively through abutment definition process. Necessary data is

inputted to graphical interfaces. To make this task easy interfaces are equipped with

graphics and described variables.

Foundation methods

ABTprovide two main foundation methods: piles and direct foundation. Bridge CADcontains

KXGmodule which export foundation pile definition data toABT.

44Loads transfer

ABT enable import of support reactions separately for every load from deck model data base

to abutment model. Its the easiest and fastest way to transform loads. Subsequently user

can calculate envelopes taking into consideration all loads on the abutment.

Flexibility

User can freely modify input data file of abutment to make changes in computational model

by using methods provided by SOFiSTiK. Changes may be executed by modifications of

generated *.dat file in every part like: geometry, foundation, loads etc.

ABT output file

ABT produce output file with defined abutment geometry and its all loads. This part of

abutment design work is most time taking. Later in SOFiSTiK user can in fast and easy way

finish task by defining combinations and design calculations according to specified code.

With ABT abutment design can be faster; therefore designer can spend more time to

optimize the structure.

Work method

KXG calculates the features of the co-operation of any subsoil with foundation piles. Program

generates a structure of horizontal spring supports arranged along the axis of piles and

vertical spring support below base of piles.

Types of foundation piles:

all types of piles areavailable

both square and round

cross-section of pile are

included

Soils parameters:

Calculations:

calculation for all

directions of the

horizontal load as well

as for each pile

separately

66Program Interface

KXG Interface leads user intuitively through pile stiffness calculation. Soils definition is

currently presented graphically on soil profile.

Scheme of pile foundation

KXG includes an innovative scheme of pile foundation which allows calculating the stiffness

of pile for several directions of the horizontal load and for different pile spacing. The scheme

is used to generate the authentic pile arrangementin the designed foundation.

77Results printout

KXG allows printing results of both horizontal and vertical stiffness of pile and maximum

horizontal soil response. Scope of printout includes both sections of the calculations i.e. the

graphic and text parts for each pile and direction of the horizontal load.

KXG data export

KXG allows exporting results of performed calculations. On the basis of the foundation

scheme user defines average soil stiffness and easily transfers data to ATB (cooperating both

modules).

WithKXG deep foundation design can be faster; therefore designer can analyze abutment

together with pile foundation.

Enjoy !
