Abstract

The paper presents results of the temperature measurements of the steel bridge in Puławy over the Vistula River. Measurement data were obtained from the construction monitoring system which is the one of three subsystems of which the monitoring system is composed to measure various physical quantities. Presented data refer to period of time from May 2009 to April 2011. Based on the gathered measurement data, the ranges of temperature changes, extreme values and differences between the values for specific types of the elements were analyzed. The differences between various types of the elements were analyzed as well. Presented data give the overview of the temperature level of the steel bridge with mediate localization of the deck. A comparison of selected values with normative values in Polish code (PN-85/S-10030) as well as in Eurocode has been made.
