摘要：Glass fibre reinforced polymer (GFRP) profiles are finding increasing applications in civil engineeringstructures, owing to the several advantages they offer over traditional materials. However, due to the combustiblenature of their polymer matrix, there are well-founded concerns about their behaviour at elevated temperature andunder exposure to fire. These concerns are hindering the widespread acceptance of GFRP profiles, particularly inbuildings, which need to comply with relatively strict requirements in terms of fire reaction and fire resistancebehaviour. Even though the GFRP structural shapes are available, the designers of such component are facing problemin the design since reliable design criteria is lacking. Thus there is an urgent need to understand the behaviour of theGFRP structures and their components under various types of loading and support conditions. This thesis reports anexperimental and analytical study by using finite element software ANSYS on the flexural behaviour of I–sectionbeams made of GFRP profiles. Tests were first carried out on coupon specimens, in order to determine the materialproperties of the GFRP specimens used in experimental investigation. Full scale tests were then conducted on simplysupported beams with span 800 mm subjected to transverse load at the top flange mid-point. The first part of the paperis aimed at investigating the flexural behavior under service and failure conditions experimentally, the objective of thesecond part is to study the analytical behavior of the flexural members by simulating the finite element model of thebeams using SHELL element in ANSYS. The results obtained confirm that, due to the low Young’s modulus and highstrength, the beam structural integrity is often governed by excessive deformation criteria or local and global bucklingcriteria.
