Abstract
Design of Cilaki River Bridge functioned as the accesss linking Kundur
Orchard, Mekarwangi Village, Muncang Subdistrict and the Sangiang Orchard,
Sindangsari Village, Sajira Subdistrict. Because of the increase in traffic flow,
Cilaki bridge must have the capacity and is able to withstand heavier loads. On the
previous planning, it was designed using suspension bridge structure with the type
of stiffening truss. On the latest planning, it is designed to use steel truss bridge
structure, thus has been estimated to be able to withstand the loads more than 5 tons
from the previous planning. Upper structure design, which is a steel truss part, has
been designed with the help of the SAP 2000 software, while the connections, floor
slabs, shear connector, bridge support/bearing, and lower structure design are
planed to use manual calculation. On the current planning, the bridge is arranged to
have 35 metres length, a total of 6 metres bridge width, and 5 metres of vehicle
deck. Upper structure of a bridge is designed by using warren steel frame type
Bj 37 by using I profile steel and elbow profile steel, with a stringer length of 5
metres, cross girder 6 metres long, stringer spacing of 1.25 metres, cross girder
spacing of 5 metres and the bridge frame is 6.35 metres height. Joint connections
uses high-quality bolt of A325 type and weld. Shear connector has quality of Bj 37.
The vehicle deck of a bridge is 0.20 metre thick and its sidewalk plate is 0.45 metre
thick with yield stress (fy) 240 Mpa and fc 24.9 Mpa. Bridge support/bearing is
designed with joint – joint bearings. Lower structure of a bridge is designed to use
24.9 MPa of concrete quality (fc) and 240 MPa of steel yield stress (fy). The
dimension of an abutment is designed to have@�X ‘¢t@ôÙj�•�q@ metres wide, and 3.9
metres high. The foundation is designed to use 2 pieces of caisson foundations with
a diameter of 1.7 metres and a height of 3.3 metres. Soil protection is put in front
of abutment, so that the soil can’t be eroded by the flow of river water that can lead
to land subsidence of approach embankment. Therefore, the abutment should be
given a protection by using gabion shape I.
Key words: Steel truss bridge, Connector, Plate, Abutment, Foundation
