10. From safety standards to safety assessment and design

10. From safety standards to safety assessment and design#

Note for students#

This chapter describes how requirements for the design and safety assessment of flood defences can be derived based on a given acceptable failure probability. Firstly, in Sec:ss_gen_princ, some general principles are introduced. Secondly, Sec:rel-bas_req introduces how specific requirements for the design and safety assessment of flood defences can be derived using probabilistic and a semi-probabilistic approaches. The elaborations equally apply to design of (new) flood defence structures and to safety assessment of existing structures. For the course on Flood defences, the following knowledge is required; all of Sec:ss_gen_princ; Subsec:RBR-intro–Subsec:Distr_sect; and basic principles of Subsec:Der_designvalues and Subsec:Calibration, but not all details.

Learning objectives#

After studying this chapter students are able:

  • To understand and explain the meaning of the new safety standards and how they are used in design and safety assessment

  • To derive the required failure probability at the section and failure mechanism level (for a given set of factors)
