Integración de la metodología BIM en la evaluación estructural de un paso peatonal

Abstract

Pedestrian crossings are structures designed taking into account the safe and accessible transportation and land communication needs of users. Their evaluation is multidisciplinary and includes the appropriate use of materials, the type of structural support, the topography, the consistency of the terrain and the budget, among other factors, complemented by the corresponding regulations. Although there are currently various tools for three- dimensional modeling of structures, the BIM methodology stands out for the effectiveness and reliability of the analyzes unlike the traditional methods used. It facilitates early detection of conflicts and errors, allowing more precise planning and management, reducing costs and execution time. The objective of the research was to address the implementation of BIM in the structural evaluation of pedestrian crossings based on the flow diagram methodology, taking as a case study the pedestrian crossing located in the city of Quito - Ecuador, northern sector of the city. The study consisted of using the BIM tool in the generation of both the architectural and structural digital model, and then carrying out the evaluation of the structure according to the parameters established in the NEC-15, the AISC and ACI. With respect to the results obtained for the vibration period in accordance with the aforementioned regulations, the analysis revealed an increase of almost 30% when comparing the modeling of the current state with the verification carried out.
