3. Thermal loads
When pre-crimped parts are subjected to significant temperature variations, stress variations due either to a difference between the bolt temperature T B and the part temperature T P , or to a difference between the bolt linear expansion coefficients α LB and the part linear expansion coefficients α LP , are generally not negligible.
3.1 General expression of effort variation
If we note T 0 the reference temperature (temperature at prestressing), we have :
-
change in bolt length due...
