A Study of Climatic Effects on Roof Systems at Cape Hatteras, North Carolina.
Abstract
A heat-transfer model was used to conduct a comprehensive study of nine composite roof systems for six building structures subjected to weather conditions at Cape Hatteras, NC. Based on analysis of the time-temperature regimes in the roof systems, numerous temperature and durability parameters were determined quantitatively. The durability parameters evaluated included the number of freeze-thaw cycles, rates of temperature change, lengths of freezing and thawing periods, and the range of temperature change. The thermal strains in the various roofing layers were determined for unbonded interface conditions, and the transient heat flux was determined for the nine roof systems. (Author)
