CSI ETABS 20.1.0

ETABS 20.1.0 Enhancements - Date: 31-Mar-2022
Structural Model
A new general shear wall hinge has been added, which consists of a pair of orthogonal P-M3 or Fiber P-M3 hinges, plus a linear or nonlinear shear material. These features allow the hinge to be used for modeling spandrels as well as piers, and to handle more complex wall geometries, such as near openings or geometry transitions. General shear wall hinges can be used for nonlinear static, staged-construction, and direct-integration time-history analyses.

The age of concrete at which loading is applied can now be specified for long-term cracked-section analysis. Previously, the age at loading was assumed to be 7 days

Design
- The CSA A23.3-19 code has been added for concrete frame design.
- The CSA S16-19 code has been added for steel frame design.
- The CSA S16-19 code has been added for composite beam design.

Data Files
The handling of time history functions defined in external data files with many data points has been significantly enhanced for speed.

New section-property database files have been added for steel sections produced by Indian manufacturers TATA, Jindal Steel Ltd. and APL Apollo Ltd.

ETABSis an engineering software product that caters to multi-story building analysis and design. Modeling tools and templates, code-based load prescriptions, analysis methods and solution techniques, all coordinate with the grid-like geometry unique to this class of structure. Basic or advanced systems under static or dynamic conditions may be evaluated using ETABS. For a sophisticated assessment of seismic performance, modal and direct-integration time-history analyses may couple with P-Delta and Large Displacement effects. Nonlinear links and concentrated PMM or fiber hinges may capture material nonlinearity under monotonic or hysteretic behavior. Intuitive and integrated features make applications of any complexity practical to implement. Interoperability with a series of design and documentation platforms makes ETABS a coordinated and productive tool for designs which range from simple 2D frames to elaborate modern high-rises.
ETABS version 20.1.0 includes the General Wall element for Performance-Based Design; the latest Canadian codes for steel frame, concrete frame, and composite beam design; enhanced control for cracked-deflection calculations, and other enhancements.
