LinSAP is a cross platform, user-friendly, interactive structural analysis program designed to be used by civil engineers. It is composed of two parts. The first part focuses on constructional analysis using a matrix method to find forces at the connections of beams and columns. The second part utilizes a graphical user interface program in order to describe the frame structure of the building; after analyzing the system, it shows resultant forces and movements.

It is intended to be a cross-platform program which is working on Linux at the same time on Windows. For this purpose we prepared our Graphical User Interface using wxWindows. Following screen shot shows LinSAP working on Linux.
