This paper presents the experimental result for four-season for steel-concrete composite bridge girder in Iraq. The model was put in an open environmental condition to be subjected to variation in thermal loads, these loads are solar radiation, ambient air temperature, and wind speed. The model was equipped with seven thermocouples in concrete and seven thermocouples in steel and one between steel and concrete to measure temperature. This article aims to provide an experimental measurement to understand the behavior of temperature distribution in Iraq. The practical study is the first in Iraq to be conducted on this type of bridge. The result showed the solar intensity, ambient air temperature and wind speed are higher effects for a sunny day, and the temperature distribution inside the girder, for the same thermocouple the temperature shows different behavior concerning the season.
