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.
