 EPISODE 19 GARUDA VARADHI FLYOVER GROUND SUPPORTING FRAME COLLAPSED

Date of Incident: 25/1/2021

Contractor: AFCONS

Fatalities - Officially NO

About the Incident:

Usually due to some site constraints, some spans will be casted with Ground Support System where LG Launching is not possible, 

In the Incident, there was a down Gradient from the pier to pier levels, even they used the standard Ground Support System which is normally used in Segment/Viaduct Construction. Due to improper interlocking with the end tower with pier might be the reason of the Span Collapse.

 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
