Abstract :
Prestressed concrete has been widely used as a
construction material, specifically for long spans bridges.
Segmental precast concrete is proposed based on the
following advantages: quick and easy in construction
compared to cast-in-place method; better control of
concrete strength; minimizes loss of prestress caused by
shrinkage and creep due to properly maintained under
factory controlled conditions. In this study, an analytical
investigation was carried out to determine the joint shear
key behavior of a PCI-girder precast concrete segmental
bridges. By analyzing the value of live and dead loads
applied to the bridge, the shear force and flexural moment
that occurs at each joint in the segmental PCI girder will
be obtained. The value of the maximum shear force that
occurs at the end of the bridge is 1138 kN. the value of the
maximum flexural moment that occurs in the middle of the
bridge is 1111 kNm. All of these data are then used for joint
girder analysis in further research, namely the analysis of
joint girder modeling using the finite element method.
