The Measurement of Temperature Stress Caused by Sunshine Action of Steel Truss

According to the fact that the research about temperature stress of steel structure is few. In this paper, a factory steel truss which support raw material pipeline as an example, taking the 34-hour on-site continuous strain test on the steel truss caused by sunshine temperature. The experimental results show that the temperature stress has a great influence on the internal force of steel truss. And the results can provide a basis for engineering design.
