Behavior of Reinforced Concrete Frames with Reinforced Concrete Partial Infills

The addition of reinforced concrete (RC) infilled walls has been found to be a feasible strengthening technique for earthquake resistance. This article reports on a study that investigated the behavior of nonductile reinforced concrete (RC) frames strengthened by introducing partial infills under cyclic lateral loading. The study was done in response to problems experienced during earthquakes in Turkey that occurred in the last decade. For the study, seven one-bay, two-story, 1/3-scale test specimens were constructed and tested. The test frames had deficiencies commonly observed in residential RC buildings. The aspect ratio of the infilled wall and its placement configurations were the parameters of the experimental study. Test results revealed that partially infilled nonductile RC frames exhibited significantly higher ultimate strength and higher initial stiffness than the bare frame (frame with no infill). The study also investigated strength and ductility inadequacies of the frame members. The authors conclude that the most successful behavior was obtained from specimens with partially infilled walls connected to both the columns and beams of the frame.
