“…The high load-bearing capacity made CGFW lose its deformability, which was a common problem for infill wall structures. 31,32 Figure 9 shows the stiffness (P/δ)-load curves of the specimens. The initial crack points of the specimens were related to the stiffness stability points, and the vertical stiffness of CGFW and CGF decreased significantly before the initial crack occurred.…”

Experimental and numerical studies were conducted to investigate interaction between reinforced‐concrete grid frame (CGF) and ceramsite foam concrete (CFC) infill. In the experiments, compressive tests were performed on the CGF and RC grid frame filled with the CFC which forms a composite wall, namely CGFW. To investigate the mechanical properties of the CGFW and the interactions between the CGF and CFC infill, the failure modes, integral stiffness, local strains, and load distribution coefficients of the composite wall were analyzed. The experimental results indicated that the CFC infill could uniformly transmit loads and significantly improve the bearing capacity and vertical stiffness of the CGFW while reducing the ductility of the composite wall. The load distribution coefficients of the CFC infill were stable at 0.51 ± 0.06 before peak load and damage evolutions in concrete columns were effectively alleviated due to obvious interactions between the CGF and CFC infill. To evaluate the interaction mechanisms of the two, numerical analysis was carried out by changing the sizes of central grid, opening rates, and reinforcement ratios of the composite walls. The finite element model with plastic damage constitutive of concrete was calibrated by comparing the experimental results. The numerical results indicated that the interaction between the CGF and CFC infill was insensitive to changes in grid sizes, and the interaction between the two was significantly different with the same reinforcement method of frame beams and columns. In addition, the CFC infill played an important role in the stability of CGF as the opening rate significantly affected the mechanical properties of the CGFW, and a stable path of load transfer was the key factor to ensure the interaction between the CGF and CFC infill.

“…The behaviour of GFRP infill laminates were incorporated in RC-frame structures and evaluated lateral displacements. The experimental test results revealed that both the strength and the initial lateral stiffness of an RC frame structure could be increased with the application of GFRP laminates [2].…”

This paper presents an explicit behaviour of Reinforced Concrete frame by considering the masonry infill wall material fully and partially in the structure. A two storey 2D frames of six different cases and 10 storey 3D building of four different cases with fully and partially assignment of infill masonry walls. Analysis was performed in E-TABS software for all the 10 cases by generating synthetic earthquake matched time history with response spectrum. The study was carried out the effect of infill wall on the behaviour of column. The results were discussed and maximum storey displacements were taken in to consideration to study the behavior of the structure. The Storey displacements for the ten cases were taken in to account and revealed that higher displacements were observed in the cases with the partial infill and effect on column due to the partial or absence of infill wall adjacent to the column.
