The main objective of this investigation is to study the flexural behavior of Ferrocement-LGS composite section when subjected to 4 point monotonic load. Ferrocement panel and LGS is connected with self-tapping screw at different spacing. 3 different spacing of 125mm, 150mm and 250mm screw connection is analyzed under flexural loading to understand the deflection behavior and moment capacity of section. Experimental study & research determine the result in terms of loadcarrying capacity, central deflection, bending moment capacity, Load vs Deflection curve and failure pattern. These results will be compared with each other. Expectation from this research is that this research will be used as guidance for future research on composite system for building construction.
