About CSI
Founded in 1975, Computers and Structures, Inc. (CSI) is recognized globally as the pioneering leader in software tools for structural and earthquake engineering. Software from CSI is used by thousands of engineering firms in over 160 countries for the design of major projects, including the Taipei 101 Tower in Taiwan, One World Trade Center in New York, the 2008 Olympics Birds Nest Stadium in Beijing and the cable-stayed Centenario Bridge over the Panama C****. CSI's software is backed by more than three decades of research and development, making it the trusted choice of sophisticated design professionals everywhere!

CSI produces five primary software packages: SAP2000; CSiBridge; ETABS; SAFE; and PERFORM-3D. Each of these programs offers unique capabilities and tools that are tailored to different types of structures and problems, allowing users to find just the right solution for their work. SAP2000 is intended for use on civil structures such as dams, communication towers, stadiums, industrial plants and buildings. CSiBridge offers powerful parametric design of concrete and steel bridges. ETABS has been developed specifically for multi-story commercial and residential building structures, such as office towers, apartments and hospitals. The SAFE System provides an efficient and powerful program for the ****ysis and design of concrete slabs and foundations, with or without post-tensioning. PERFORM-3D is a highly focused nonlinear tool offering powerful performance based design capabilities.

SAP2000 Overview
The SAP name has been synonymous with state-of-the-art ****ytical methods since its introduction over 30 years ago. SAP2000 follows in the same tradition featuring a very sophisticated, intuitive and versatile user interface powered by an unmatched ****ysis engine and design tools for engineers working on transportation, industrial, public works, sports, and other facilities.

From its 3D object based graphical modeling environment to the wide variety of ****ysis and design options completely integrated across one powerful user interface, SAP2000 has proven to be the most integrated, productive and practical general purpose structural program on the market today. This intuitive interface allows you to create structural models rapidly and intuitively without long learning curve delays. Now you can harness the power of SAP2000 for all of your ****ysis and design tasks, including small day-to-day problems. Complex Models can be generated and meshed with powerful built in templates. Integrated design code features can automatically generate wind, wave, bridge, and seismic loads with comprehensive automatic steel and concrete design code checks per US, Canadian and international design standards.

Advanced ****ytical techniques allow for step-by-step large deformation ****ysis, Eigen and Ritz ****yses based on stiffness of nonlinear cases, catenary cable ****ysis, material nonlinear ****ysis with fiber hinges, multi-layered nonlinear shell element, buckling ****ysis, progressive collapse ****ysis, energy methods for drift control, velocity-dependent dampers, base isolators, support plasticity and nonlinear segmental construction ****ysis. Nonlinear ****yses can be static and/or time history, with options for FNA nonlinear time history dynamic ****ysis and direct integration.

From a simple small 2D static frame ****ysis to a large complex 3D nonlinear dynamic ****ysis, SAP2000 is the easiest, most productive solution for your structural ****ysis and design needs.
