BEHAVIOR HORIZONTALLY CURVED I GIRDER Description of curved I girder I girder beam or I girder uses mostly in a bridge to support smaller deck. Load from girder is to transfer a load to vertical support as pier or column. There are several types of I-girder: rolled I-girder, plate girder... Rolled I-girder is standard girder, manufactured at a factory as size in standard code. Plate girder is built up from various members. Plate girder is actually a deep beam and there are 3 types: box girder, hybrid girder & delta girder. Name of each girder is following how to use them in structure. Box girder made to resist torque, hybrid girder is a type of girder with different material in the same section. The last plate girder is delta girder provided lateral support. Curved I-girder has been used in bridges in the US since the 1950s, and has a complicated behavior compared to a straight beam. Some of the problems that curved girder faced are torsion, flange lateral bending, lack of stability and buildability concern. However, nowadays curved skewed I-girder bridges are used widespread and have a specific percentage of total. Horizontal curved/skewed I-girder bridge has advantages in saving material and simplifying structure by curving along roads and reduce intermediate supports. Curved and skewed I girder bridge easily to have significant deformation. The deformation would be considered during design, in detailing and erection up. Depending of geometry of bridge, engineer would
