Effect of Masonry Infill Walls with Openings on Nonlinear Response of Steel Frames

The infill walls are usually considered as nonstructural elements and, thus, not taken into account in analytical models. However, numerous researches have shown that they can significantly affect the seismic response of structures. aim present study is to examine role masonry on damage steel frame without and with various types openings systems subjected nonlinear static analysis time history analysis. For purposes above investigation, a comprehensive assessment conducted using twelve typical masonry, full different heights widths openings. results revealed influence successive earthquake phenomenon structural larger for buildings compared bare Furthermore, when analyzed sequences, it great importance orientation motion. indicated opening area has an maximal strength, ductility initial rigidity these frames. But shape will global behavior. Then, indicates displacement greatly decreased even behavior curve affected by intensity considered. Doi: 10.28991/cej-2021-03091653 Full Text: PDF
