Abstract:Simple for Dead load and Continuous for Live load (SDCL) steel bridge system has proven to be economical for non-seismic application. Although the system has been used in different methods of construction, this paper concentrates on Accelerated Bridge Construction (ABC) application. The application of the SDCL steel bridge system in high seismic areas has been nonexistent, mainly due to lack of appropriate details. The extension of the SDCL system to high seismic areas was initiated by conducting detailed numerical analysis to comprehend types of forces that the connection must resist. The results of the numerical study lead to development of connection details over middle pier. Thereafter, a component testing of the proposed SDCL connection was carried out to find the ultimate limit states, verification of numerical results, and merits of the proposed detail in light of established seismic design provisions. The developed connection behaved as designed and prevented damage to capacity protected elements. The column showed sufficient ductility during cyclic tests, which indicated the connection will perform well under high levels of displacement.
