THE FINITE ELEMENT ANALYSIS OF HEAT CONDUCTION FOR THE CONCRETE STRUCTURE HAVING UNCERTAIN MATERIAL PROPERTIES

Abstract

An analytical procedure which deals influencing factors affecting to temperatures in the structure is herein proposed. Factor analyses were conducted against the thermal characteristics affecting to thermal analytical results by means of the method of sensitive analysis. The variances of temperature in the structure having variable thermal characteristics of concrete and environment were evaluated from the sensitivity obtained by the sensitive analysis and the approximated theory using Taylor's expansion.
