Investigations on the behavior of composite frame integral bridge due to the environmental change

摘要

In this research, in order to investigate the response behavior of the integral bridge due to temperature change, the environment and temperature on each part of a bridge were measured for an actual bridge. Moreover, in order to simulate the response behavior of the bridge, heat transfer analysis and heat stress analysis were carried out. Consequently, it is confirmed that the analytical value shows good agreement with the measured value, and it was made clear that the bridge response by temperature change could be reproduced by the analysis.
