3rd Croatian Conference on Earthquake Engineering 3CroCEE

With the introduction of 3D graphic representation to improve workflows, communications, collaborations, and data exchange among all members involved in the project, the BIM (Building Information Modeling) methodology is completely transforming the structural industry. In general, BIM is fundamentally based on an information-sharing methodology among all stakeholders, implemented throughout the building's life cycle and materialized through the use of specialized software in the virtual construction of a 3D digital model. In this particular case, the process of seismic assessment and strengthening of RC five storey building will be presented through a series of steps, using BIM methodology. Based on the previously performed analyses of the structure and obtained results, it has been defined which elements of the structure need to be strengthened. In this case, using the BIM platform PlanRadar for organizing and managing the process, it is demonstrated how the seismic assessment of the building and the process of strengthening the elements would be carried out. This methodology, using the PlanRadar platform, allows for the proper planning of all activities that are part of the strengthening procedure of the building. Each defined location in the structure contains its own data card. It specifies the name and type of the task, who defined the task and for whom it is intended, when it should start, the location in the structure, the type of strengthening, details of the strengthening for the structural element, as well as the steps for the gradual installation of the FRP materials. This procedure offers opportunities for complete control of the process, allowing for the review of both models (the architectural and the structural), as well as the ability to control whether the elements requiring strengthening are permissible for architectural reasons or due to other design phases.
