Analysis of Embodied Energy and CO2 in buildings structures under seismic action: wood, reinforced concrete, steel

摘要

This study analyzes some different typologies of structures made of different materials: wood, reinforced concrete and steel. Furthermore, the structures are tested, calculated and verified in different seismic sites according to the set of antiseismic regulations for constructions in force in Italy. The geometric pattern corresponds to a type of construction typical in Italy but also widespread abroad: some central shear walls wind and earthquake resistant and a frame made up of beams and columns. The calculation model gives the amount of materials used. We considered the values of CO2 production for wood, reinforced concrete and steel in accordance with University of Bath, Inventory of Carbon & Energy (ICE) Version 1.6. The results show the values of CO2 produced and Embodied Energy for the construction of these structures. The report doesn't deal with LCA but allows to assess the effect on the environment in the life cycle of a wood, reinforced concrete, steel structure, and then to choose the right typology of structure.
