논문 초록 (Abstract)

Snowstorm, slippery pedestrian walkways, ice and snow on pavement and roofs of structures continue to serve as a threat to lifeand infrastructure in many low temperature nations. Owing to thes e menaces coupled with an increase in the demand and cost of energy glo bally, engineers and planners are tasked to design effective and eff icient green technologies to counterbalance these demands. Snow melt ing systems are gradually gaining widespread application in the a reas of bridge, pavements and roofs of buildings. Snow melting loads are an integral part in the design of snow melting systems. This pa per developed snow melting and roof snow building load for the R epublic of Korea. Annual averages and frequency distribution methods we re used in the analysis of a 10-year period weather data. Monthly total as well as peak snowfall rate values were usedto generate annual and p eak snow melting load values, respectively. It was observed that the annual-average approach is more conservative for most clima tic conditions than the frequency analysis method. Minimum flat roof snow building loads were presented to aid in the structural anal ysis of structures within the Republic of Korea. The developed data base in this paper will provide the database for designing a snow meltin g system and for analyzing the building structural interpretation consid ering snow weight. © 2015 World Scientific Publishing Compa ny.
