Assessing Riprap Stability at Bride Piers and Abutments
This online engineering PDH interactive presentation provides an advanced numerical modelling approach to evaluate rock stability at bridge piers and abutments.
Riprap is one of the most common materials used to protect bridge abutment and pier foundations from scour. A key element of the design of riprap countermeasures is rock sizing, which is based on equations generally derived from simplified laboratory experiments.
This 1 PDH online interactive presentation is intended primarily for designers and engineers responsible for protecting bridge foundations.
This continuing education interactive presentation is intended to provide you with the following specific knowledge and skills:
- Assessing whether detailed fluid structure interaction (FSI) modeling can inform evaluation of rock riprap movement for both the analysis of existing riprap aprons and for the design of new riprap aprons
- Developing recommendations for the design, installation, and monitoring of riprap aprons at bridge piers and abutments, where feasible
- Testing the FSI approach on a complex field case study of a riprap installation at a pier for a bridge
Once you finish watching the PDH interactive presentation, you will be redirected to your account to take a multiple-choice quiz consisting of ten (10) questions to earn 1 PDH credit. The quiz will be based on this interactive presentation.
