Intra Infilled reinforced concrete (RC) frame (IF) is one of the most common types of structures used in low and medium rise building, especially in the area where affordable materials and labor are available, including in the area with high seismicity. Opening on the wall is part of the architectural design to house windows and doors of various sizes and location within the wall. Though openin...

The inelastic response of existing reinforced concrete (RC) buildings without seismic details is investigated, presenting the results from more than 1000 nonlinear analyses. The seismic performance is investigated for two buildings, a typical building form of the 60s and a typical form of the 80s. Both structures are designed according to the old Greek codes. These building forms are typical fo...

Accurate modeling of masonry has been a major concern of the researchers in the past decades. Besides reinforced and unreinforced masonry structures, masonry can be found in frame structures as infill panels which are used as partitions and/or external walls. These elements role as a part of structure and introduce a large degree of nonlinearity into the system. In this study, a micro-modeling ...

The Open Construction & Building Technology Journal is presently publishing a Special Issue on Infilled Framed Structures focusing on the Experimental & Modelling Aspects. It has been established that masonry infill walls affect the strength, stiffness and ductility of infilled frame structures. However, when designing such structures, it has become common practice not to include the existing i...

During a baseball game, the ball will strike the playing surface at a variety of speeds and angles. The speed at which the ball travels after impact with the playing surface has been referred to as the pace of the surface. Wide variations in pace can reduce the safety and playability of baseball field surfaces. Pace can be quantified by measuring the coefficient of restitution. The coefficient ...

This study aims to investigate the effect of infilled frames through various important parameters (i.e., openings’ percentage in infill walls - several columns on first floor are removed partial infilled) RC structures, subject progressive collapse scenarios. To this end, 3D finite element models were constructed by using software ABAQUS. Numerical and experimental results compared substantiate...
