SAP2000是集成化的通用结构分析与设计软件。 适用于桥梁、工业建筑、输电塔、设备基础、电力设施、索缆结构、运动设施、演出场所和其它一些特殊结构的设计。
 自从三十前SAP诞生以来，它已经成为最新分析方法的代名词。SAP2000保持了原有产品的传统，具有完善、直观和灵活的界面，为在交通运输、工业、公共事业、体育和其它领域工作的工程师提供无出其右的分析引擎和设计工具。 在SAP2000三维图形环境中提供了多种建模、分析和设计选项，且完全在一个集成的图形界面内实现。在今天的市场上SAP2000已经被证实是最具集成化、高效率和实用的通用结构软件。 在这个直观的界面里，你不需要进行长时间的学习，就可以很快地设计出直观的结构模型。您能够驾驭SAP2000去完成所有的分析与设计工作，包括日常碰到的小问题，利用内建强大的模板可以完成复杂的建模和网格划分。 先进的分析技术提供了：逐步大变形分析、多重P-Delta效应、特征向量和Ritz向量分析、索分析、单拉和单压分析、Buckling屈曲分析、爆炸分析、针对阻尼器、基础隔震和支承塑性的快速非线性分析、用能量方法进行侧移控制和分段施工分析等。 桥梁设计者可以用SAP2000的桥梁模板建立桥梁模型，自动进行桥梁活荷载的分析和设计，进行桥梁基础隔震和桥梁施工顺序分析，进行大变形悬索桥分析和Pushover推倒分析。 每个人都可以使用SAP2000! 每个项目都可以采用SAP2000！从简单的二维框架静力分析到复杂的三维非线性动力分析，SAP2000能为所有结构分析和设计提供了解决方案。
CSI SAP2000 version 18.x | 942.6 mbComputers and Structures, Inc. (CSI), a structural and earthquake engineering software company, has released 18.0.1 version of SAP2000, is general-purpose civil-engineering software ideal for the analysis and design of any type of structural system.Basic and advanced systems, ranging from 2D to 3D, of simple geometry to complex, may be modeled, analyzed, designed, and optimized using a practical and intuitive object-based modeling environment that simplifies and streamlines the engineering process.The SAPFire Analysis Engine integral to SAP2000 drives a sophisticated finite-element analysis procedure. An additional suite of advanced analysis features are available to users engaging state-of-the-art practice with nonlinear and dynamic consideration. Created by engineers for effective engineering, SAP2000 is the ideal software tool for users of any experience level, designing any structural system.Integrated modeling templates, code-based loading assignments, advanced analysis options, design-optimization procedures, and customizable output reports all coordinate across a powerful platform to make SAP2000 especially useful for practicing professionals.SAP2000 19.0.1 Enhancements:Graphical User Interface
- Assign and select menu forms have been enhanced to allow them to remain open for repetitive use with a new apply button.
- DirectX graphics mode has been enhanced to use DirectX 11 for enhanced speed and capabilities.
- 64-bit version of the graphical user interface (GUI) now available.
Modeling
- New 2-D modified Darwin-Pecknold concrete model has been added to the nonlinear layered shell. This model represents concrete compression, cracking, and shear behavior under both monotonic and cyclic loading, and accounts for crack rotation.
- Semi-rigid option added for diaphragm constraint.
- Modify undeformed geometry feature enhanced to allow applying the modification to a selection of joints, as well as limiting direction of modification.
Loading
- Ability to specify accidental eccentricity for response spectrum cases added.
- Automated response spectrum functions according to the Costa Rica Seismic Code 2010, Ecuador (NEC-SE-DS 2015), Korean KBC 2009, Mexico (CFE-93 and CFE-2008), and Peru (NTE E.030 2014) codes added.
- Auto-seismic loading according to Korean Building Code (KBC 2009) added
- Auto-seismic loading according to the Dominican Republic (R-001) code added
Analysis
- A new stability check has been added for nonlinear static load cases to report when the structure may have failed under material or geometric nonlinearities that are not obvious from the analysis results.
- The handling of convergence tolerances for time-dependent behavior during staged-construction analysis has been improved to better enforce equilibrium after large load increments.
International Frame Design Codes
- Concrete Frame Design - ACI 318-08, -11, -14 enhancement allows specifying Design System Rho (ρ) and Design System SDS factors in the concrete frame design preferences.
- Steel Frame Design - Eurocode 3-2005 enhancement to perform a basic torsion design for I- and tubular sections.
- Steel & Concrete Frame Design - Korean Building Code (KBC 2009) code added
- Steel Frame Design - Russian SP 16.13330.2011 code added
- The default design load combinations have been enhanced for ACI 318-08, -11, -14 to include roof live load patterns.
- The default design load combinations have been enhanced for CSA A23.3-04, CSA A23.3-14, CSA S16-09, and CSA S16-14 to include companion loads.
Output and Display
- Contour plots are now available for frame deflections and axial stresses.
- The center of mass is now reported in the Assembled Joint Masses table for each mass source.
External Import/Export
- The export to Revit Structure has been enhanced to export steel sections parametrically such that Revit can import the section dimensions if it cannot match the section name.About Computers and Structures, IncFounded in 1975, Computers and Structures, Inc.
