Abstract

Abstract

The effect of temperature on long-span space structures cannot be ignored. Temperature effect values related to the area, taking Urumqi Railway Station steel roof space truss structure as engineering example, combined with Urumqi meteorological data and the result of flow field analysis, different types of temperature effect accessor methods were put forward, and then the different types of temperature effects were taken into account in structural finite element model for temperature effect analysis, according to the deformation and force of the structure, it was concluded that the extreme daily temperature difference and the extreme annual temperature difference were the most unfavorable loads, which should be considered in the future structure design.
