| description | In article calculates the coefficients of transport transverse installation for steel-reinforced concrete bridge structure with the use of off-center compression methodology. Two design models of beam continuous span structure of bridge central part were simulated in the Lira-SAPR software package. Based on the numerical data obtained the coefficients of transport transverse installation (TIC) were determined and the nature of transport temporary mobile load’s distribution between main beams of the bridge was revealed. As a result of research a comparative analysis of transport transverse installation coefficients was accomplished, obtained by theoretical and numerical methods. The research established in contrast to the engineering analysis methodology using the eccentric compression method the most loaded is the middle main beam B4 when four traffic lanes are located across the span. Analysis of main beam using engineering methodology assumes that the bridge deck is loaded with three traffic lanes. Based on results of the spatial model analysis in the LIRA-SAPR software were constructed lines of pressure influence on the outermost (B1) and middle (B4) main beams and for each of them were calculated TICs. In course of comparative analysis it was determined the TIC from the temporary moving load AK-15 for the main outer beam B1, determined using the engineering method of eccentric compression, is on average overestimated by 38.7% compared to TIC determined by the numerical method. The coefficient of performance coefficient from the temporary moving load AK-15 for the main middle beam B4, determined using the engineering method of eccentric compression, is on average underestimated by 11.96% compared to TIC determined by the numerical method. |
