ETABS是由CSI公司开发研制的房屋建筑结构分析与设计软件，ETABS已有近三十年的发展历史，是美国乃至全球公认的高层结构计算程序，在世界范围内广泛应用，是房屋建筑结构分析与设计软件的业界标准。目前，ETABS已经发展成为一个建筑结构分析与设计的集成化环境：系统利用图形化的用户界面来建立一个建筑结构的实体模型对象，通过先进的有限元模型和自定义标准规范接口技术来进行结构分析与设计，实现了精确的计算分析过程和用户可自定义的（选择不同国家和地区）设计规范来进行结构设计工作。

ETABS除一般高层结构计算功能外，还可计算钢结构、钩、顶、弹簧、结构阻尼运动、斜板、变截面梁或腋梁等特殊构件和结构非线性计算（Pushover， Buckling，施工顺序加载等），甚至可以计算结构基础隔震问题，功能非常强大。

ETABS已经贯入的规范包括：UBC94、UBC97、IBC2000、ACI、ASCE（美国规范系列），欧洲规范以及其他国家和地区的规范。ETABS在全世界超过100个国家和地区销售，超过10万的结构工程师在用它来做设计工作。

CSI ETABS 2013 version 13.x | 692.8 mb

Computers and Structures, Inc. (CSI), leader in software tools for structural and earthquake engineering, has released an update to CSI ETABS 2013 version 13.1, is a civil engineering program that design and analyse steel and concrete structures using finite element method.

ETABS 2013 provides an unequaled suite of tools for structural engineers designing buildings, whether they are working on one-story industrial structures or the tallest commercial high-rises. Immensely capable, yet easy-to-use, has been the hallmark of ETABS since its introduction decades ago, and this latest release continues that tradition by providing engineers with the technologically-advanced, yet intuitive, software they require to be their most productive.

Significant enhancements included in ETABS 2013 version 13.2.0 and version 13.2.1:

- The Auto-Relabel All option that was available in ETABS v9 has been restored.

- Russian material property and section property libraries have been added.

- ASCE 41-13 guidelines for performance-based design have been implemented for frame hinge definitions, performance-point calculations, and the behavior and acceptance criteria for panel-zones and BRBs (buckling-restrained braces).

- Masonry is now defined as a separate material rather than a type of concrete material.

- Multiple named mass-source definitions can now be created and used for different load cases.

- The Singapore National Annex has been added as an option to the Eurocode 8-2004 response spectrum function.

- Notional load patterns can now be based on snow loads as well as other gravity loads.

- User control is now provided for the handling of self-weight in the end offset portions of beam members.

- The speed of analysis has been increased for most load cases.

- The iteration strategy for nonlinear static and nonlinear direct-integration time-history load cases has been made more adaptive to typically improve convergence behavior and to reduce the time of analysis.

- The line-search algorithm is now available for nonlinear static analysis.

- Steel frame design for the Indian IS 800:2007 code now implements the changes in Amendment Number 1.

- The display of design input parameters for steel frame design overwrites has been enhanced.

- Canadian design codes (i.e., CSA A23.3-04 and CSA S16-09) now include snow loads in the default design combinations.

- Multiple enhancements have been made for composite beam design affecting the control of the design process, the look and functionality of the interactive design form, the format and content of the output, and other improvements.

- Shear wall design per the Indian IS 456:2000 code now allows separate control in the major and minor directions for enforcing the minimum eccentricity due to slenderness.

- Several database tables have been added or have had their content expanded, including the listing of object unique names where applicable.

- Table set definitions are now saved in the text model file.
