CU-EWA
CU-EWA is a computer program developed by A. Sarawit to compute the nominal flexural strength, Mn and the nominal axial strength, Pn using two approaches: the AISI (1996) method initial yielding and the Proposed Design Approach for flexural members given by Schafer (1997), Schafer and Peköz (1999). This approach was shown to be applicable to complex stiffeners by Sarawit and Pekoz (2000).This program uses the Mathworks, MatLab environment.

CU-PBF
CU-PBF is a FEM computer program developed by A. Sarawit to solve three types of problems involving the eigenvalue analysis: plate elastic buckling, free-vibration, and free-vibration with initial in-plane stresses. The program uses the finite element method with four-node rectangular thin plate elements. Various boundary conditions and perforations can be applied.
This program uses the Mathworks, MatLab environment.
CU-TWP
CU-TWP is a computer program written by A. Sarawit to determine cross section properties of thin-walled members.
CU-FSM
CU-FSM is a finite strip developed by B. W. Schafer for the analysis of of thin-walled sections. A more recent version of the program may be available from the author B. W. Schafer.
CU-BEAM
Tour
CU-BEAM developed by B. P. Gotluru is for the analysis of single span and continuous beams. Performs a simple approximate geometric nonlinear analysis. User-friendly. Any arbitrary thin-walled sections can be accommodated. Also calculates and reports the section properties of the sections. Can be run on Windows 95/NT or above. Interactive help file is also available.
CUSRF
CUSRF is a computer program written by A. Sarawit to analyze semi-rigid frames. A users manual will be available in future.
