Recently new materials and technologies for construction industry have been introduced. So, existing fire safety technology can no longer handle the current situation effectively. Developed countries have already adopted performance-based approaches to structural fire safety. Prior to the introduction of performance-based design, studies many variables have to be conducted. Among these, the heat flow is directly related to fire behavior and affects direction in spread of fire. In addition, heat flow is largely affected by the factors such as location and size of openings. This paper aims to evaluate the applicability of moving particle semi-implicit (MPS) method for heat flow analysis. In this paper, a heat flow analysis program is designed adding the energy equations and buoyancy term in the algorithm that Koshizuka originally developed. In addition a numerical analysis and experiment had been conducted and compared through temperature distributions to verify the reliability of the program. Experiment shows very close result as what is analyzed by the program, confirming the applicability of MPS method for heat flow analysis.
