The aim of this paper is to provide an overview of seismic detailing to the Nevada Department of Transportation (NDOT) Structures Manual and American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Standards for single span bridges located in the state of Nevada, US, with reference to Project Neon and the I15-CC215 Interchange Project. In general, detailed seismic analysis is not required for single-span bridges regardless of the seismic zone. However, the connections between the bridge superstructure and the substructure shall be designed for the minimum force requirements as recommended by AASHTO. Also, the minimum support length requirements in accordance with AASHTO shall be satisfied at each substructure. Concrete shear keys or cheek walls are, therefore, provided on the abutments to resist the lateral seismic forces, whereas dowel bars are provided to resist longitudinal seismic forces at pinned abutments. The substructure elements are detailed with transverse confinement reinforcement at plastic hinge locations as recommended by NDOT and AASHTO. |
