The paper presents experimentally registered temperatures occurring in RC grouped silo bins for grain, corresponding to winter operation period in Polish climate conditions. A new generation wireless computerized measurement system was applied, based on the use of telemetric transceivers operating in intelligent radio network. On the basis of experimental temperature distribution, numerical analysis of the hoop thermal stresses and bending moments in reinforced concrete silo battery subjected to grain pressure and thermal gradient was carried out. In the analysis the numerical model of silo wall with interaction between wall structure and stored particulate solid was applied which had previously been developed and validated on a stand-alone ferroconcrete silo bin model.
