  EFFECT OF SKEW ANGLES IN BRIDGES This Article is a compilation of the below Technical Papers, only the Essence of the Papers are provided here for quick grab in this section, detail report is attached below. A Bridge built obliquely between the Supporting Spans are called as Skew Bridge. The angle between the normal to the center line of the bridge and the center line of the abutment is known as Skew Angle. Skew bridges are built where geometry cannot accommodate straight bridge. Alignment should be straight to facilitate high speed and safety requirements of the traffic, this resulted in increase in number of skew bridges. Study 1: This study comprises of Seismic analysis of Box & T Girder Bridges using Response Spectrum Method performed using SAP2000 varying skew angles of the Bridges. Responses of the Substructure, Girders and Deck are studied. An attempt was made to determine skew angle up to which skew bridges have comparable characteristics with straight bridges and also t

 DESIGN FORCES IN METRO BRIDGES This Article is a compilation of the below Technical Papers, only the Essence of the Papers are provided here for quick grab in this section, detail report is attached below. I Girder of span 25m & Box girder of span 40m of metro bridge were considered. Analysis of substructure and superstructure for all static and dynamic loads as per various code and then a comparative study has been done between design forces. IRS Code, EURO Code, &  California high speed rail authority guidelines are used for comparative Codal  References. IRS: CBC suggests higher partial safety factors for dead  load, SIDL and live load in load combinations. Therefore,  moment, shear force calculated as per IRS: CBC at  superstructure are larger as compared to Euro-code and  California high speed rail authority guidelines. Seismic forces calculated on the pier as per IRS - RDSO  guidelines for seismic design of railway bridges, are same  in the longitudinal direction and mor

  This Article is a compilation of the below Technical Papers, only the Essence of the Papers are provided here for quick grab in this section, detail report is attached below. Generally, for Bridge Super Structure we would construct Box Girder, I/T Girders, Void Beam, etc... So, we require a better understanding of Super Structure Section which best suited for a particular Spans, cost wise & Constructability point of views.   Software used: CSI Bridge   FEM method is economical than the one-dimensional analysis.   Box girder is found to be Costlier for 16.3 m Span whereas for 31 m span the box girder is economical. Box girder are more suitable in terms of stability and economy as compared to T beam girder bridge superstructure. For longer spans the depth of T-beam Girder increases drastically which makes it uneconomical. Therefore, for higher spans more than 25m the Box Girder is always suitable due to its higher torsional rigidity. For lesser spans I Girders are economi
