    Calculation of Deck Strenght When Longitudinal Girders Are 3100mm Away and No Supports in Between

    Uploaded by

    naseemtyche
    This document summarizes the calculation of deck strength when longitudinal girders are 3100mm apart and no supports are in between, and then again with two additional supports placed in between girders. For both scenarios, transverse beam, plate, and longitudinal stiffener checks were performed. With no intermediate supports, the maximum deck strength was found to be 3.202 tonnes/sqm. With two additional supports, the maximum deck strength increased to 9.121 tonnes/sqm based on the plate deflection check being the limiting factor.
