In seismic regions, everyday structural engineers have to deal with rigorous and time-consuming rebar detailing to comply with code requirements for seismic design and local rebar detailing standards. Historically, this task was done in 2D detailing software like AutoCAD software, but today the industry is based on the BIM (Building Information Modeling) environment, and it's necessary to create rebar elements inside the Revit model. This class will show you how this approach was accomplished, continuing with a class presented at Autodesk University 2017-“BLD124825-Automatic Rebar Detailing of Wall-Based Buildings Using Dynamo and ETABS.†At that time, development was done in Dynamo, but to reach the desired productivity, the solution was migrated 100% to the Revit API. The goal of this class is to share the experience of the process, along with the stream of decisions related to geometry analysis and simplifications on rebar detailing with different local practice industry and seismic design standards.
