ATIR STRAP 2009 (STRuctural Analysis Programs) is a Windows XP/2000  based suite of finite element static and dynamic analysis programs for buildings, bridges and other structures. It also includes programs for the design of rolled and light-gauge steel and concrete in accordance with U.S., Canadian and other international codes. Current Version 2009 is our 10th release for the Windows platform.

STRAP is one of the most comprehensive and versatile structural analysis and design software systems available on the market today. It's also the easiest to use, due to its superb graphic user interface (GUI) and advanced context-sensitive help system. It offers the engineer a powerful but affordable tool for analysis and design of a wide range of skeletal and continuum structures such as buildings, bridges, shells, towers and more.

STRAP uses graphical CAD-like input in the generation of models and loads. Every drawing on the screen can be printed, imported into other documents, or (through DXF) into drawings. Complete analysis and design can be performed for any structure without ever referring to joint or beam numbers. Load combinations can be created after analysis is performed. Results of the load combinations can be reviewed instantaneously without rerunning the model.

For the engineer interested in dynamic effects, STRAP also includes modules for modal analysis, seismic response spectra calculations to the UBC and California codes and time history response calculations.

The learning curve to start using STRAP is practically non-existent. The program's flow is similar to the analysis and design process performed by hand. During the execution of every action the prompt line at the bottom of the screen guides you through. Combine this with the unique built-in, context-sensitive Help and you can understand why many of our users don't even know where their STRAP manual is.

Hardware requirements to run STRAP are minimal: a PC running Windows XP,2000,98 or NT and 35 MB of free hard drive space.
