Purpose. To develop a scientifically substantiated and experimentally validated method for modelling the behaviour of a fibreglass I-beam profile with structural fire protection under the high-temperature effect of fire, taking into account changes in its stress-strain state, in the ANSYS software-computing complex.
Methods. Analysis, modelling, comparison of existing results of experimental and theoretical research on the subject under study.
Findings. Application of ANSYS Composite PrepPost (ACP) module for numerical modelling of building structures made of composite materials under high-temperature conditions is considered. The stages of construction of geometrical model of fibreglass I-beam profile, determination of properties of multilayer composites and heat and mechanical calculation are described. The results of the simulation were compared with experimental data, confirming the high accuracy of the method for simulating the behavior of fiberglass I-beams.
Application field of research. Design and construction of buildings and structures using polymer composite (fibreglass) materials and structures.
