ASTRA Pro software is based on Grillage modelling and analysis of Deck-Girder superstructure by using Finite Element Method for structural analysis. The Non-Linear Stage, Orthotropic and Dynamic Analysis for Bridges are done in the simplest way. Finally by choosing the analysis results the design is done. Taking user’s General Arrangement Data in Dialog box model is created making that editable in GUI and finally processes the selected analysis to generate Detail Analysis Report with on screen display of results and visual presentation of 3D dynamic rotation view and animated model for Load deflection. Next, the structural detail design is done with step wise Design Report. A set of sample editable structural detail CAD drawings is provided for the selected bridge. The sample drawings are convertible to design drawings by drawing converter or by editing manually.

In analysis suite, there are ‘Normal Analysis’, ‘Stage Analysis’ and ‘Dynamic Analysis’, out of these analysis the ‘Normal Analysis’ is mandatory other analyses are optional. The ‘Stage Analysis’ is also known as Non Linear Analysis or P-Delta Analysis or Force Deflection Analysis. The analysis is carried out for 5-stages, if the design life of the bridge is 100 years then each five stages shall be of 20 years and shall give forces and deflections by applying Dead Load, Superimposed Dead Load and Live on the deflected shape of the previous stage.

Initially (immediately after construction) if the allowable deflection for a bridge span is ‘Span/1500’ that is to be tested by on-site load test on the bridge. If the deflection is within span/1500 then the load capacity (rating capacity) is partly alright. Next, upon unloading the bridge span in stages if the deflection recovery is found up to 85%, then the load capacity (rating capacity) is finally alright.

This load test is to be conducted after 20, 40, 60, 80, and 100 years of age of the bridge, if the respective deflections are within the values found by stage analysis then the condition of the bridge is alright at that respective ages, otherwise other Non-Destructive Tests (NDT) may be carried out and decision may be taken whether to go for rehabilitation or replacement of the bridge. The deflection may be by the deformation in the superstructure, substructure or bearing and that may be observed by reading from sensors attached at strategic locations of the bridge.

Next, user has to go to section ‘Design Forces’ in ASTRA Pro and select ‘Normal Analysis’, and then select ‘Design on Analysis’ to get the design results in respect of selected design forces. The sample CAD drawings may be edited as necessary, as per user’s design data and the design results.

Bridge Design – Design of Composite Bridge in Curved Alignment

For Trucks heavily loaded with stone aggregates, sand, marble slabs, cement bags, steel members etc. when negotiates curve the centrifugal force is very high. If the transverse force is considered same as straight bridge, by ignoring the effect of centrifugal force then the design of the Bridge and Bearing is incorrect resulting fall of the curved span.

The essential considerations in this design are:

• Modelling of the bridge as a curved super-structure with three span continuous structure
• Applying transverse force at support nodes with correctly selected POT/PTFE Bearings obtained from the X and Z direction components of the centrifugal force.
• Construction drawings for Composite Road Bridge with Steel Box Girder and RCC Deck Slab
