Abstract: This paper presents the results of an experimental and analytical investigation of an infill wall system using HPFRCC for retrofitting frame structures. The system is designed for flexibility in application, ease of replaceability, and protection of secondary systems. Experimental studies have been conducted on individual panels of the infill using engineered cementitious composites (ECC) with and without mild steel reinforcement. Experiments on individual panel response to cyclic lateral load showed that the panels fail primarily in a flexure mode. The reinforced ECC panels could reach strengths 45% higher than a reinforced concrete panel, demonstrating a unique structural effect of ECC material behavior. A constitutive model for ECC was developed and applied to simulate panel response. Detailed finite element models were conducted to study the performance of the panels with different materials and the performance of the connections to a steel frame. It was determined that localized yielding of the connection region did not occur.
