Effect of unreinforced masonry infill walls with and without ECC layer on the performance of RC framed structure
Recently, reinforced concrete infilled frames (IF) are widely employed in construction worldwide. Despite its significant interaction with the bounding RC frame, the infill is typically regarded as a nonstructural element and is not taken into consideration during design or analysis. A layer made of Engineered Cementitious Composite (ECC) has recently been used to modify the behavior of many structural components. Eleven frame models were examined in this study: the bare frame (BF-0), the infilled frame (IF-0), the infilled frame with a single layer of ECC (IF-1), and the infilled frame with double layers of ECC (IF-2). The first four frames were chosen as single-degree of freedom (SDOF) models. The other seven frames, however, were MDOF (multi-degree of freedom) models. Through nonlinear pushover analysis with the SeismoStruct programme, a verification investigation on earlier experimental work was carried out. The collected results demonstrated that adding an ECC layer or layers to the infilled frame models boosted their in-plane capacity. When compared to the bare frame model, adding an infill panel to the model raised the peak load by more than 70%. The capacity of the infilled-framed was improved in SDOF models by around 17% and 20%, respectively, when a single or double ECC layer or layers were used. Using the ECC layer to strengthen the first narrative of MDOF models offers a higher enhancement ratio of about 73%.
