FUNDAMENTAL STUDY ON THE THERMAL PROPERTIES OF CONCRETE STRUCTURAL MEMBERS UNDER EXTERNAL HIGH TEMPERATURE LOADING

Abstract

Heat conduction and thermal stress problems of reinforced concrete members and steel-concrete composite members are discussed based on the experimental and theoretical points of view under external high temperature loading condition such as 1000°C. Finite element analysis using an extended embedded model for reinforcements is presented to solve the three dimensional thermal problems of these members. In addition, the heat conductivity and Young's modulus of concrete are measured under such high temperature.
