The present work aims to determine the efforts of the stringer of a reinforced concrete bridge, following the norms standardized by ABNT (Brazilian Association of Technical Standards). Since this type of structure, classified as a special work of art, is of utmost importance for man to run through barriers and exercise his inherent right to come and go. In order to determine the active loads, it was based on the ABNT NBR 7187: 2003 (Reinforced Concrete and Concrete Bridges Project - Procedure) and ABNT NBR 7188: 2013 (Mobile road and pedestrian load on bridges, overpasses, walkways and other structures). From the loads obtained, the Engesser-Courbon methodology was applied, which, through influence lines, determined the parcel of load distributed in each beam. When analyzing the influence line, it was possible to find the most requested beam and to dimension the longitudinal and transverse reinforcement through ABNT NBR 6118: 2014 (Concrete Structures Project - Procedure) and ABNT NBR 7187: 2003. Were also used for the development of this work the softwares ftool® version 4.00.04 and FlexCisTor software version 2.8. |
