Abstract |
It has been verified that there is an effect of diminishing in section bringing in internal core section reinforcement and external prestressing rather than general plate-girder bridge as a consequence of analysis. In particular, positive effect was seen in the aspect of usability when external prestressing was in application as rises gained from it minimized the hanging down of a bridge. Based on the result of analysis, a sectional diagram applicable per number of girder has been illustrated which made it possible to estimate the intensity of internal stress in the futurewhere number of girder is limited to 4 and regression equation is presented after regression analysis has been carried out.
