摘要：

Composite lintels, are formed above the door and window openings of glass-fiber-reinforced gypsum (GFRG) wall constructions. These lintels are constructed by filling reinforced concrete into the hollow cores of the GFRG walls. The GFRG panel itself is a composite material composed of gypsum plaster and the reinforcing glass fiber. When filled with reinforced concrete the structural action of the lintels is derived from further composite action between the GFRG panel and the infill concrete. Experimental beam testing was conducted to study the flexural and shear behavior of these composite lintels. Typical failure modes and corresponding ultimate strengths were obtained and analyzed. Based on the test results, theoretical design models and guidelines are proposed,for both the flexural and shear strengths.
