Abstract :
In recent years, the steel shear wall system has been used integrally in steel frames, but the appropriateness of using this system in prefabricated concrete frames is in the development stage. Little research has been done on the behavior of prefabricated concrete frames reinforced with steel shear walls. This article deals with the laboratory investigation of steel shear walls connected to precast concrete frames by bolts and nuts. Three different samples were subjected to reciprocating quasi-static loading according to ACI-374 regulations. All laboratory models include a one-story prefabricated concrete frame with hinged connection of the boundary members for corners of the frame and also a screw connection of the boundary members to the filler plate. In the first laboratory sample, a carbon steel plate was used and in the second laboratory sample, a galvanized plate was used as a steel shear wall, while the third laboratory sample did not have a steel shear wall and only a prefabricated concrete frame was used. The results show that contrary to the initial assumption in the design of the beam-to-column connection in the laboratory samples, they behaved semi-rigidly and in both samples with carbon steel and galvanized steel plates, the stiffness increased 4 times compared to the prefabricated concrete frame with the semi-rigid connection. The resistance of the final steel shear wall with carbon steel plate and galvanized plate has increased by 337% and 591%, respectively, compared to the prefabricated concrete frame. Using a steel shear wall system can significantly improve the stiffness and strength of the structure. Also, the results showed that the prefabricated concrete frame is in an elastic state until the end of loading and energy is absorbed by steel plates. Finally, the investigations showed that using steel plates in prefabricated concrete frames increases energy absorption significantly.
