Figure 4.
The drawing shows a longitudinal section of a bridge with labelled structural segments and marked thermal meter locations. The main section view spans from the left end A to the right end I and is labelled as Section A A. Red squares indicate thermal meters placed on the deck, soffit, concrete deck, deck chord, and bottom chord. Circled numbers highlight typical installation zones referenced in enlarged details below. Four detail views are shown beneath the main section: soffit detail with sensors S 1 to S 5, deck chord detail with sensors D 1 to D 5, concrete deck detail with sensors C 1 to C 5, and bottom chord detail with sensors B 1 to B 5. Each detail includes sensor spacing dimensions and scale information.Thermal sensors on (a) the QC girder section: (b) detail of the soffit, (c) detail of the deck chord, (d) detail of the concrete deck, € detail of the bottom chord
