| Abstract: | The main deficiencies of the existing measuring device for deformation of concreter during high temperature are the data ac- quisition by the influence of concrete burst in certain degree and the need of special cooling system. To solve these defects, this paper designs a simple device of measuring concrete deformation under high temperature which can make up for the deficiencies of existing measuring deformation device during high temperature. It has been verified by the high temperature test that the simple device is safe, reliable, and meet the accuracy requirement during high temperature test. Additionally, it has the advantages like the simplicity of in- stallation and operation, and it is economical, safe and practical with reliability of test data. |
