In-Depth Information
To calculate the coefficients of thermal expansion, we define the expansion
length of the concrete as half the sum of the lengths perpendicular to the
expansion joint of the slabs on both sides of the joint. This definition is adopted to
conveniently calculate the
Apparent Coefficients of Thermal Expansion
(ACTE) for the structure in service, and express said coefficients in temperature
units to allow their comparison. The assigned expansion length of concrete was
47.35 m (155.3 ft) for the southern sensors.
