【Abstract】 The thermal strain at and thermal damage to the notch of the arch concrete specimen are tested by the electrometrical method and supersonic method, and the thermal damage to the specimen structure under thermal loads is described. The effect of thermal loads on thermal damage is indicated, and the failure mechanism of concrete thermal damage is analyzed. The results provide a foundation for theoretical research of concrete thermal damage and for engineering design.更多还原
