MATERIALS AND DESIGN OF PREFABRICATED ELEMENTS
|LANGUAGE OF INSTRUCTION and EXAMINATIONS||
|The aim of the course is to educate the 5th-year students of the Department of Civil Engineering in basic concepts and principles of prefabrication of reinforced concrete structural elements including the main properties of special (targeted and/or high) performance concrete and prestressing steel used in the precast industry.
At the end of this course the student will:
• know general concepts and principles of prefabrication of structural elements (and assemblages) made of reinforced concrete and will be able to distinguish the differences between a prefabricated and a conventional structure.
• know the technology and properties of special (targeted and/or high) performance concretes and prestressing steel used in the precast industry and the specific fields of application of such concretes.
• know the types of prefabricated reinforced concrete structural elements and their connection methods.
· know basic principles regarding the preliminary design of precast concrete elements (seismic behavior,structural stability).
· know (to some extend) special aspects regarding the behavior of precast concrete elements (causes of damage, fire resistance,durability)
· be able to write comprehensive technical reports on prefabrication-related issues and present their contents to the public.
