Requires: Design Level
Designs are performed using the analysis results from VisualAnalysis and the parameters specified for each member Design Group or plate Design Mesh. American Concrete Institute strength design provisions (ACI 318-11) are checked to determine whether the members or plates meets code requirements. In order to determine the controlling design loading, an iteration is performed for each element, at each location in that element where results exist and for each strength load case defined.
The process starts with a specification of member or plate configuration and minimum size parameters. The software will search for acceptable preliminary designs, incrementing the size as required. Design selections are presented along with suggested reinforcement details that you can modify. A final check is then performed on your selection. Note, however, that the VisualAnalysis model will not be changed, as this would cause results to become invalid and thrown out. Instead, the Design Group holds the results until the model is synchronized. Once the design changes are synchronized, the model must be re-analyzed in order to get final unity checks.
You may use either metric or USA rebar types in the design of concrete. There is a preference setting for all future projects and there is a project setting in the Project Settings to direct VisualAnalysis to select rebar from the appropriate category for you during the design process.
