Refinement of the Transverse Installation Coefficient of Transport for Steel-Concrete Bridge Spans
Abstract: The paper calculates the coefficients of transverse installation of vehicles AK-15, NK-100 and pedestrian load for the main beams of steel-concrete bridge structure with the use of off-center compression. In the course of engineering calculation the section of the extreme main beam of the bridge construction is checked in accordance with the requirements of the first and second group of limiting states. Two design models of the beam continuous spanning structure of the central part of the bridge construction were simulated in the Lira-SAPR 2013 software complex. Based on the numerical data obtained, the coefficients of transverse installation of transport were determined and the nature of the distribution of the temporary mobile load of transport between the main beams of the bridge was revealed. As a result of the research a comparative analysis of the coefficients of transverse installation of transport was acomplished, obtained by engineering and numerical methods.
Keywords: transverse installation factor (TIF), steel-concrete bridge construction, main beams, temporary mobile transport load, out-of-center compression method, final elements (FE).
