TO STUDY THE EFFECT OF NUMBER OF CELLS IN 2-LANE AND 4-LANE PRE-STRESSED BOX GIRDER BRIDGE DECK by Romila
Bridges are the key elements in any road construction network, use of box girder is gaining popularity in bridge engineering fraternity because of its better stability, serviceability, economy, aesthetic appearance and structural efficiency. The structural behavior of box girder is complicated, which is difficult to analyze in its actual conditions by conventional methods. In present study 2- lane & 4-lane Prestressed Box Girder Bridge is analyzed for moving loads, dead load & Prestressed load, as per Indian Road Congress IRC:6-2014 “standard specifications and code of practice for road bridges”, Prestressed Code IS: 1343-2012: code of practice for Prestressed concrete& IRC:18-2000 for “Prestressed Concrete Road Bridges” specifications. The analysis of box girder is done by using CSIBridge2016 and Prestressed with parabolic tendons which utilize full section. The various spans 40m, 50m & 60m are considered to study the effect of no. of cells for 2-lane & 4-lane at which stresses, B.M, S.F and deflection are compared.
