The contribution of masonry infill walls (MIW) to the dynamic behavior ofreinforced concrete (RC) buildings is investigated in this study. An existingnon-symmetrical, six-story reinforced concrete building has been used as a testspecimen. Dynamic characteristics of the building have been determined bythe ambient vibration survey (AVS) first. Then, the masonry infill walls on itsground floor were completely demolished, and the obtained new form of thebuilding was studied by AVS. Later on, two forms of the building weremodeled to visualize its behavior under ambient conditions, and the dynamiccharacteristics of the building have been determined numerically. The attainedexperimental and numerical results for both forms of the building were compared,and the constructed numerical models of the building were calibratedby an interactive tuning algorithm defined according to the specific dynamicfeatures of the building. As the last numerical analysis, all MIW were removedfrom the verified numerical model of the building and the dynamic analysiswas repeated. The main goal of the study was accomplished by comparing theexperimentally and numerically obtained dynamic results on the basis of dominantfrequencies, mode shapes, torsional behavior, and soft story mechanism.
