Step wise detail design calculations and production of CAD drawings for GAD, Structural Detailing and making changes whenever essential are the main requirements in Computer Aided Bridge Design. The process in ASTRA Pro is straight forward and can be mastered in no time even by the beginners and students.

Stream Hydrology is computed in details from Terrain Topography by transforming Transverse marcator data to Universal Tranverse marcator (UTM) data, Referring to WGS84 origin and directly downloaded from Shuttle Radar Topography Mission (SRTM) without Topo maps. Discharge Location at Bridge is measured from farthest point of the River for water discharge at the Bridge location. The environment is 3D CAD, fully compatible to other CAD softwares.

Synthetic Unit Hydrograph is plotted by comparing sum of discharge for 1 hour interval of Time and volume of 1 cm direct Runoff.

Bridge Design is a complex subject, so the Software must provide the user ready data to produce a Design. Next user easily understands which data is to be changed and how to prepare the design data to fit his/her project requirements. ASTRA Pro guides the users to learn through the process of work, and it works perfectly.

The essential steps are computation of Self weight for Fixed or Dead Load (DL), Weight of hand Rails, Kerb Stone, Wearing Course as Superimposed Dead Load (SIDL), Moving vehicle Loads in Multiple Lanes as Live Load (LL) and applying these loads and do the Analysis of the Bridge Structure for Maximum Member Forces as Axial Force, bending Moments, Torsion and Shear, Using the Maximum Member Forces Design of the Structural members and Finally produce the drawings for Construction.

Analysis Design of Cable Stayed Bridge is facilitated by large size Model Data for the Bridge Structure.

ASTRA Pro is not just an Analysis Software, it produces Step by Step Design Calculations Report for the user making references to relevant Indian or British Standards and Structural Drawings in editable CAD form ready with Title Block.

ASTRA Pro processes Analysis for Applied Dead Load (DL), Super Imposed Dead Load SIDL) and Live Load (LL) by Moving a train of vehicles in Single or Multi Lane configuration of the Bridge Deck. User may do the analysis with either by applying individual Loading or may do the analysis by applying combined loading. In CAD engine ASTRA Pro shows the Moving Load in Animated form displaying load case wise member end forces.

ASTRA Pro produces worst member forces for Bending Moments, Shear Force, Axial Forces at various locations of the model, including Inner Girder, Outer Girder, Cross Girder, Stringer Beams, Truss and Cable members to enable the engineer to design various structural components of the Bridge.

ASTRA Pro designs the Bridge Substructures for RCC Pier and Abutments by taking the Bending Moments and Reactions from the Analysis. It also produces the design of Well/Pile/Open Foundations with CAD drawings.

ASTRA Pro offers the users to analyse a structure with Beam, Truss, Plate/Shell and Cable elements. The analysis may be done for Static as well as Dynamic. In Dynamic analysis it features for Eigen value problems, Response Spectra and Time History Analysis.

ASTRA Pro offers the users to select the design standard either as Indian Standard or as British Standard.

ASTRA Pro offers the users to analyse a structure with Beam, Truss, Plate/Shell and Cable elements. The analysis may be done for Static as well as Dynamic. In Dynamic analysis it features for Eigen value problems, Response Spectra and Time History Analysis.

ASTRA Pro produces CAD drawings compatible to AutoCAD and other drafting software to edit the various drawings to make them ready to use for the construction.

General Arrangement Drawing in PLAN with Details for Proposed Expansion Joints, Crash barriers, Girder Positions, Abutment & Pier Positions, Foundation, Upstream & Downstream sides etc.
