ABSTRACT An attempt is made to prevent shear failure in composite structure of RCC lintel and flyash brick masonry above it. Hear we consider RCC lintel and the flyash brick masonry altogether as a composite structure. In a wall openings with the lintel beam and masonry above, the two components act together in supporting the load. The composite action of lintel with masonry above is a complex phenomenon. RCC Lintel specimen of spanning 1.5 meter were constructed with the depth of 101.6 mm (4 inches) and a width of 228.6 mm (9 inches). The reinforced bars of 8mm diameter (4 nos.) were cut and tied with distribution bas of 6mm diameter (8 nos.) with the help of G.I. wires. In addition, 3nos. of concrete cube of size 150mm×150mm×150mm were tested and the compressive strength is calculated, relating to the RCC lintel-beam. Three specimens of RCC lintel (of same cross section) and brick masonry above it were tested, from that thespecimens were cast with masonry above the lintel up to three, six and nine layers in English bond of flyash brick masonry. This lintel-masonry walls were tested to failure under two point load and their load deflection curve was plotted. And the comparative study of theoretical and experimental shear strength has been done. Index Terms: composite structure, flyash brick masonry, shear failure, RCC lintel, load deflection curve, bending moment and shear force diagram
