Download TwoDFrame 2.35

Please read first.

TwoDFrame comes with two license modes: Academic/Teaching and Commercial.

Universities / Polytechnics / Professors / Lecturers / Students (Academic/Teaching):
TwoDFrame is a big help for thousands of students in more than hundred countries on five continents. The Academic mode is and will be free of charge and without any burocratic hurdles for academic / non-commercial users. Just download and begin!
Professors and lecturers are asked to mention TwoDFrame at relevant places (e.g. homepages, lecture notes, publications).

Engineers and others (Commercial): You are welcome to download and to test TwoDFrame, but you must pay the license fee before using TwoDFrame on a project. TwoDFrame is not 'freeware'. However, licenses are sold for a small price.

Most of the features are running without a license number and may be freely used for teaching purposes, e.g.: First order analysis of two-dimensional frames or continuous beams, timber design according to Eurocode 5, steel design according to Eurocode 3, reinforced concrete design according to Eurocode 2, ouput of all matrices of the matrix displacement method (stiffness method).

The following advanced analysis options are enabled with a valid license number: Second Order Analysis (P-Delta), Elastic Foundation, Model Column Method, Elastic-Plastic-Design (E-P), Plastic-Plastic-Design (P-P), Buckling Design, Modal Shapes, Modal Analysis, Modal Superposition, Dynamic Loads, Spectral Acceleration, Support Acceleration, Response Spectrum Analysis, Time History Analysis.
License numbers for academic purposes are and will be distributed for free and without burocracy to professors and lecturers. Students can use the advanced analysis options for free in the computer labs of the universities. Free license numbers for the students' private computers are not available. We kindly ask for your understanding. Students are asked to contact their lecturer.


It is recommended that you download frame___.zip (11.2 MByte; please check after download!) to your harddisk, extract frame___.exe, and then execute frame___.exe as administrator (right mouse button or long tap).

Windows 8.1 / 8 / 7 / Vista: To install, uninstall and change the license settings, you must run setup / TwoDFrame as administrator (right mouse button or long tap). Otherwise, data is redirected to the 'virtual store' and TwoDFrame may not behave correctly.

Safety: All our files are checked against computer viruses with the latest McAfee VirusScan software. However, it is good practice to scan downloaded files against computer viruses after they have travelled through the internet: Our Server (safe) -> Internet Server 1 (safe?) -> Internet Server 2 (safe?) -> ... -> Internet Server n (safe?) -> Your Computer (safe?). Always stop, if your anti-virus software detects anything.
