Experimental and Numerical Investigation of Float Glass–GFRP Hybrid Beams

Despite the great potentials of glass as a construction material, its brittle material behaviour poses major challenges to structural engineers when designing load-bearing glass structural members. This paper presents the load response and the failure behaviour of float glass–GFRP hybrid beams, when...
