عملكرد دالهاي دو طرفه بتني مسلح به ورقهاي فولادي سوراخدار

In this study, perforated steel plates are proposed to reinforce concrete slabs. Three slab specimens reinforced with perforated steel plates and three slab specimens reinforced conventionally were cast and tested to failure. Test results and analysis show that slabs reinforced with perforated plates provide higher cracking strength, ductility, energy absorption capacity and ultimate strength than slabs reinforced with conventional reinforcement. Improve in force transfer between steel and concrete can facilitate the use of perforated plates in various applications, specially those made of composite materials with high tensile strength.
