The Quantitative Seismic Analysis of a Precast Reinforced Concrete Frame Hall and the Establishment of Retrofitting Solutions. Part I – the Dynamic Analysis of the Existing Structural System

The ventilated facade is an external building envelope system, installed dry, in new constructions or on buildings undergoing renovation. This system is mounted outside the building, with a space in front of its perimeter wall. Its main role is to influence the heat exchange between the inside and outside of the building, with advantages over heat losses. A modern material used in ventilated facades is Corian, a composite material patented by DuPont in 1967, composed of acrylic polymer and alumina trihydrate (ATH) derived from bauxite ore. Its main use is for the finishing layer on the ventilated facades of buildings, and it requires knowledge of how it behaves under the action of temperature variations. This article presents the laboratory results recorded to assess the material’s disturbed state under freeze-thaw cycles.
