This computer program was developed to simulate the behavior of composite walls and columns subjected to fire loading. The program is based on the fiber analysis method and the fundamental axial force-moment-curvature-temperature relationship of the member cross-section. For composite columns, only uniform heating (from all sides) is considered. For composite walls, uniform heating and one-sided heating are considered. Additionally, for composite walls, there is an option to simulate the whole planar wall length, or a unit width wall segment taken from the complete wall length. Two versions of the tool were developed compatible with Matlab and Octave softwares. A Graphical User Interface (GUI) was developed for the fiber model with the main aim of enhancing its usability and giving designers the ability to better manipulate the inputs and visualize the results. The GUI was developed using MATLAB App Designer. The user interface was designed with the ability to run the model in multiple ways depending on user preferences and input and display the results as interactive plots.

This version includes analysis of CFT columns (uniform heating), C-PSW/CF walls (uniform heating), and unit width C-PSW/CF walls (Two-sided and single-sided heating). The thermal material properties are based on Eurocode. Multiple structural materials properties options are provided. A Graphical User Interface (GUI) is developed in the current version. GUI allows the user to have easier interaction with the tool particularly for users not familiar with coding. The results can be displayed as interactive plots by providing various options to plot the results. A user guide is prepared for the users containing instructions on using the tool.
