Experimental results of reinforced concrete frames with masonry infills with and without openings under combined quasi-static in-plane and out-of-plane seismic loading

Abstract Reinforced concrete (RC) frames with masonry infills can be encountered all over the world, especially in earthquake prone regions. Although are usually not considered design process, case of seismic loading they subjected to in-plane and out-of-plane forces that act separately or simultaneously. In recent earthquakes it was observed loads severely damage even cause their complete collapse, when Due this, effects interaction on performance have received more attention recently. However, most studies focus only fully infilled frames, though openings, such as windows doors essential parts substantially affect response infills. Therefore, this article presents results a comprehensive experimental study nine full-scale traditional RC modern hollow clay bricks for configurations without window door openings under separate, sequential combined loading. Based results, detailed comparison interpretation different infill is presented. The test clearly show unfavourable influence conditions well importance quality execution circumferential mortar joint between frame. new findings used basis required development innovative solutions improve significantly
