DETERMINATION OF THERMAL STRESSES IN CONCRETE DAMS BY MEANS OF MODEL TESTS

DESCRIBES THE METHODS IN PRESENT USE AT THE LABORATORIO NACIONAL DE ENGENHARIA CIVIL (LNEC) FOR DETERMINING THE STATE OF STRESS DUE TO TEMPERATURE CHANGES IN CONCRETE DAMS, AND PRESENT AS ILLUSTRATIONS SOME OF THE RESULTS OBTAINED, AS WELL AS PHOTOGRAPHS OF THE INSTRUMENTS AND SETUPS USED. ACCORDING TO THE CONCLUSIONS, THE RESULTS ARE SUFFICIENTLY ACCURATE FOR PRACTICAL APPLICATIONS, AND THESE TESTS SHOULD BE CARRIED OUT WHENEVER FAIRLY IMPORTANT THERMAL STRESSES ARE ANTICIPATED. /ACI/
