Seismic Design of Concrete Structures

Module aims

  • To introduce the students to the fundamental concepts and principles required for the seismic design of reinforced concrete and masonry structures. 
  • To enable the students to develop an understanding of the seismic behaviour of concrete and masonry materials, components and systems under typical earthquake loading conditions. 
  • This knowledge can then be applied in practical earthquake resistant design of frame and wall systems according to modern codified regulations, with particular emphasis on the European seismic design code, Eurocode 8.

Learning outcomes

On successfully completing this course unit, students will be able to:

  • Understand the response characteristics of typical materials, members and components under cyclic and earthquake loads.
  • Estimate the curvature and deformation ductilities of critical structural members and components, and their use within seismic design procedures.
  • Understand the concept of performance based seismic design and the means of achieving performance goals in buildings.
  • Appreciate the key behavioural characteristics of concrete frame and wall systems under cyclic and earthquake loads.
  • Understand basic concepts of scheme design of concrete and masonry buildings for earthquake resistance.
  • Understand basic concepts of seismic design of concrete diaphragms and foundations.
  • Apply the main design rules and detailing requirements for frame and wall systems according to the provisions of Eurocode 8.
  • Have a general understanding of the methods adopted for the seismic repair and strengthening of building structures.

Module syllabus

  • Performance and design of masonry structures and masonry-infilled frames under lateral seismic loads.
  • Estimation of the flexural stiffness of concrete elements under seismic loading.
  • Introduction to displacement-based seismic design.
  • Overview of key concepts relating to the seismic design of concrete diaphragms and foundations.
