Experimental verification and analysis of temporary bridge structure actual behaviour

conference paper

English

The paper deals with the problems of the analysis and experimental verification of the actual behaviour of the structural system used for the provisional bridging purposes. This paper presents the brief information on the results of the full-scale loading test of the particular type of the temporary bridge. The subject of the loading test is the special railway bridge of the structural system of ŽBM 30, i.e. military demountable bridge developed by the railway military and used as a temporary bridge for the bridging with the span up to 30 m. This system with plate main girders and upper deck is usable for the temporary reconstruction of single-track railway bridges. The loading test has been oriented to the verification of the actual behaviour of this structural system during the loading process, with the accent to the objective load-carrying capacity and rigidity. Mainly the loading test was aimed to obtain the information and data on the actual loading of the main load-carrying structural system members, their stress states and deflections within the usual service loading actions. The loading procedure and corresponding principle of the test equipment used for the realization of the full-scale loading test have been developed and elaborated to the form of the specific loading test set-up by the paper authors. For the evaluation and generalization of the test results the analytical methods including the numerical modelling have been used.
