Abstract

Bridge represent element / part of road, that is a construction as transportation link medium between road which is one with other which blocked by barricade in the form of river, creavasse, bog, strait and others. Target to reach in this study is to know bar style eccentricity influence at buhul to capacities construct bridge and know the level of displacement effect of eccentricity mark with lines bar style at especial frame buhul of steel bridge. The planning of bridge is real bridge unfolded 50 metre and wide 10 metre with frame form K. At determination of bridge profile, for used by horizontal bar of majemuk profile 4 UNP 40, for used by vertical bar of T profile, while for the bar of diagonal used by UNP double profile 40. From result of study, at buhul plate analysis effect of line eccentricity work bar, with biggest momen effect of eccentricity ( Node 11, Me = 45,590 tm), extension plate tension at nodal 11 that happened equal to 79982,456 kg / cm2. If compared to steel permission tension (σsteel = 2400 kg / cm2, steel st. 52), extension plate tension at nodal 11 is bigger (σ >σsteel). Hence weak extension plate to arrest momen effect of eccentricity. So that at nodal 11 needed by plate addition to strengthen extension with dimension of t = 2 cm, h = 22 cm b = 85,5 cm. Tension at addition of the plate equal to 2293,103 kg / cm2. And when compared to permission tension become militant tension at the plate smaller which mean the the plate strong enough to arrest momen effect of eccentricity. While maximum style effect of eccentricity that is at bar 25 (horizontal, fx=795,314 ton), bar 4 ( horizontal, fx=814,489 ton), bar 10 is ( vertical, fx=284,489 ton), bar 31 ( diagonal, fx=277,582 ton). While maximum effect of eccentricity that is at buhul 5 ( middle unfold ) equal to 1,843 cm ( sb. x), 12,480 cm ( sb. y), and 64,047 cm ( sb. z). With existence of addition of momen effect of eccentricityke, hence displacement that happened will increase.
