Description
 
This 2-hour online course is intended for SAP2000 Bridge Design users who want to become more familiar with the seismic loading and analysis of bridge models. Participants will be guided through the definitions of the design response spectrum as well as the nonlinear material properties and nonlinear hinge definitions. A SAP2000 bridge model will be developed and used to determine the demand and capacity displacements in accordance with the AASHTO Guide Specifications for LRFD Seismic Bridge Design.
