2D Frame Analysis software package has been synonymous with state-of-the-art analysis of general and arbitrary frames and trusses in 2d space since its introduction over 14 years ago. Its user interface which is proven very sophisticated, intuitive and versatile is powered by a modern analysis engine which allows fast calculations and produces reliable analysis results. From its easy graphical modeling environment to the wide variety of analysis options, 2D Frame Analysis package has proven to be the most integrated, productive and practical general purpose structural program for static, dynamic, linear and non-linar (P-Delta effects) analysis of 2d frames or trusses. 2D Frame Analysis package has been designed to be very easy and fast in its use. Therefore, the user can conveniently take advantage of a great variety of features that are shown below in brief. Steel section and predefined materials list updated, major interface improvements, creation of completed professional looking calculation report, stress calculation added, all major measure units added.
