CSI ETABS version 21.1.0 (3261)

Computers and Structures, Inc. (CSI), is pleased to announce the availability of ETABS 21.1.0 (3261). This release offers crack-width (serviceability) design of concrete members per the Eurocode 2-2004 and Italian NTC 2008 codes, improved handling of time-history load functions, increased speed and storage efficiency for processing results of long PBD runs (such as for wind), and other enhancements.

ETABS 21.1.0 Enhancements - Date: 14-Aug-2023

Loading
Several enhancements have been made to the handling of time-history and response-spectrum functions:
- The processing of large function files, such as wind records, has been made more efficient for speed and storage.
- Functions can be added or modified after the analysis is run and the model is locked.
- More control has been given to locating function files on the local computer or network.


Analysis
Parallelized design and response-recovery have been made more efficient for speed, memory usage, and disk IO for large analysis models and/or models with many long time-history functions, such as wind records. Parallelized response recovery affects certain larger output tables and time-consuming graphical displays.


Design
Crack-width (serviceability) design of concrete members has been added according to Eurocode 2-2004 and Italian NTC 2008 codes. This feature is available for beam (M3) design and for the design or check of column reinforcement. Crack width, concrete stress, and steel stresses are calculated and compared against the limits imposed by the Eurocode 2-2004.


Detailing
An enhancement was made to show PT tendon vertical profiles in slabs and beams in Detailing drawings. Previously the PT profiles were shown in the on-screen Detailing, but not in the drawing sheets produced for printing and/or export.



ETABS is 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.
