Release Notes

Structural Components

ETABS 18.1.1 Enhancements Structural Model

Panel-zone definitions now include nonlinear behavior that is automatically generated based on ASCE 41-17 criteria or specified as user-defined properties. The nonlinear behavior for panel zones allows the specification of a symmetrical multi-linear backbone curve with several available options for hysteretic behavior. Panel-zone acceptance criteria definitions have been expanded to allow the major and minor directions to be separately specified, and these can be automatically generated based on ASCE 41-17.

Detailing

ETABS 18.1.1 Enhancements Detailing

ETABS has been enhanced for compatibility with CSiXCAD™ a new plug-in from Computers and Structures, Inc., for the detailing and documenting of steel and concrete structures within AutoCAD® or BricsCAD®. Working with building models that were analyzed and designed in ETABS, CSiXCAD can automatically create plans, elevations, schedules, and BIM models. Drawings can be updated to reflect changes to the ETABS model and design results, while retaining drafting changes made to the drawings themselves.
