ATIR.STRAP.2015.download STRAP (STRuctural Analysis Programs) is a Windows 10/ Windows 8/ Windows 7 based suite of finite element static and dynamic analysis programs for buildings, bridges and other structures. It also includes modules for the design steel sections (rolled and light-gauge) and reinforced concrete (beams, columns, slabs, walls, footings) in accordance with American, European, Canadian and other international codes. Our current version STRAP2015 is our 20th release for the Windows platform. The Solve module can now utilize 64-bit processors. The solution time for large models can be reduced up to 90% in computers with four processors 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 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 input for 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. Combinations can be changed instantly without solving the model again. STRAP comes with design modules for designing reinforced concrete, post-tensioned concrete and structural steel (hot-rolled and cold-formed) For the engineer interested in dynamic effects, STRAP also includes modules for modal analysis, seismic response spectra calculations according to many 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 context-sensitive Help and you can understand why many of our users don't even know where their STRAP manual is.
