Lightweight concrete was used in tension layer a on layer for all hybrid concrete beams. The main var knesses of RPC layer (h R =0, 50 and 100) mm, vol f LWC (porecilenite aggregate, polystyrene and saw rength (first and ultimate loads) was increased when th ased percentage were (7-100) % and (32-133) % re ads. In addition to that, these parameters were decre ever that it can be seen from the experimental results more effective than the concrete with other types of rete with porecilenite type reflected more number of c ll beams failed by flexure mode without any shear cra e tension zone.
