Seismic assessment procedures. Failure mechanisms and experimental evidence. Numerical investigation of reinforced-concrete-infilled frames. Modelling techniques. Overview of alternative retrofit strategies. Use of fibre-reinforced polymers. Flexural, shear and confinement upgrading. Diagonal metallic haunches, external walls, post-tensioned walls, selective weakening.
The course will cover the following main aspects: Overview of key and most common structural weaknesses and associated anticipated behaviour/response of existing reinforced concrete buildings. Reference will be given to experimental tests, analytical/numerical studies and the recent lessons learnt from post-earthquake building inspections and investigations. Discussion on main features and approaches of alternative seismic assessment procedures, with reference to existing national and international literature. Fundamentals of analytical and numerical modeling techniques to represent the seismic response of as-built reinforced concrete buildings Introduction to Performance-Based Retrofit Strategies and alternative solutions/techniques available/mostly used in New Zealand and/or overseas. Feasibility and efficiency of adopting and/or combining different solutions such as Fibre Reinforced Polymers, low-invasive low-cost metallic diagonal haunches, (post-tensioning or traditional) wall systems and selective weakening techniques
At the end of the course students would be expected to have gained familiarity with:a) the general concepts and principles underpinning seismic assessment and retrofit approaches, according to a performance-based philosophy;b) the relevant existing literature at national and international level for either assessment and retrofit, based on experimental, numerical, analytical studies and observations /reports from post-earthquake recognisance missions;c) the general potentiality, as well as limitations, of a range of strengthening retrofit solutions, either based on traditional or more recently developed techniques.

The students, either individually or paired in groups, will be assigned a case-study project (worth 40%). The project work will cover aspects of simplified or detailed assessment, analytical and numerical modelling of the structural response, conceptual design and performance evaluation of alternative retrofit solutions.The main findings will be presented via a written report, divided in two parts, assessment and retrofit, respectively, and, possibly, an oral presentation. A final written exam (worth 60%) is scheduled on Wednesday 27th March 2019
