This study investigates the structural performance of reinforced concrete (RC) square frames infilled with precast ferrocement wall panels and further enhanced using steel rope bracing. Three types of frame specimens were tested under diagonal compression: a bare frame (BF), an infilled frame with a precast ferrocement panel (IFFP), and a frame combining ferrocement infill with internal steel rope bracing (INBP). The primary objective was to evaluate the improvements in initial cracking load, ultimate load capacity, stiffness, and overall lateral resistance due to the inclusion of infill and bracing. Experimental results revealed that the IFFP configuration significantly improved both load-bearing capacity and stiffness over the bare frame, while the INBP system demonstrated the highest structural efficiency, with a 190% increase in load capacity and 87% reduction in deflection compared to BF. The initial cracking load for the INBP was approximately 9.5 times higher than that of the bare frame, indicating the effectiveness of the steel bracing in delaying initial damage. Finite Element Analysis (FEA) using ABAQUS software corroborated the experimental findings. This study highlights the potential of combining precast ferrocement panels and non-bonded internal steel bracing as a cost-effective, replaceable, and seismically resilient solution for RC frame systems.

摘要

This study investigates the structural performance of reinforced concrete (RC) square frames infilled with precast ferrocement wall panels and further enhanced using steel rope bracing. Three types of frame specimens were tested under diagonal compression: a bare frame (BF), an infilled frame with a precast ferrocement panel (IFFP), and a frame combining ferrocement infill with internal steel rope bracing (INBP). The primary objective was to evaluate the improvements in initial cracking load, ultimate load capacity, stiffness, and overall lateral resistance due to the inclusion of infill and bracing. Experimental results revealed that the IFFP configuration significantly improved both load-bearing capacity and stiffness over the bare frame, while the INBP system demonstrated the highest structural efficiency, with a 190% increase in load capacity and 87% reduction in deflection compared to BF. The initial cracking load for the INBP was approximately 9.5 times higher than that of the bare frame, indicating the effectiveness of the steel bracing in delaying initial damage. Finite Element Analysis (FEA) using ABAQUS software corroborated the experimental findings. This study highlights the potential of combining precast ferrocement panels and non-bonded internal steel bracing as a cost-effective, replaceable, and seismically resilient solution for RC frame systems.
