PERIODO: MAGGIO 2018


Il corso sarà tenuto dal prof. Antoine NAAMAN della University of Michigan e dal prof. Francesco ROMEO della Sapienza di Roma.

Il corso si focalizzerà sul ferrocemento, inteso sia come materiale che come tecnica costruttiva. In particolare, si farà riferimento alle problematiche e alle strategie di analisi legate alla progettazione e conservazione di questo materiale nelle strutture civili esistenti.

The main objectives of this course are to: 1) familiarize participants with the definition, behavior and design of ferrocement and laminated cementitious composites using continuous reinforcement of steel or other advanced materials; 2) help them understand their behavior and mechanical properties; 3) provide them with the basic knowledge of the mechanics of ferrocement and methods for its accurate analysis; 4) prepare them for the design of structural elements or systems using ferrocement composites; 5) introduce them to the only existing building code on ferrocement, 6) describe examples of applications, 7) address particular aspects related to durability, repair and rehabilitation, and seismic analysis of heritage structures, and 8) provide students with sufficient knowledge and confidence to effectively address ferrocement structures.
The course will provide students with an opportunity to gain knowledge about the conservation of modern ferrocement and concrete buildings. The training will include an overview of some important case studies currently under preservation programmes, such as the Sydney Opera House, the Flaminio Stadium and Torino Esposizioni, built by Pier Luigi Nervi, and Pavilion V by Riccardo Morandi. Conservation issues will be addressed, also in view of rehabilitation needs, including technical solutions to deterioration and material failure.

Recommended Prerequisite: basic concepts of structural engineering (behavior, analysis, design, construction).
