The stiffness of masonry infill walls is commonly neglected in design practice Reinforced Concrete (RC) structures. In fact, the wall may significantly influence seismic performance and dynamic behavior RC buildings. this research, to structural a three-story frame investigated. addition, possible application friction-based support also studied. Full 3D non-linear time history analysis conducte...

After learning from several devastating earthquakes in China in recent years, stricter design criteria have been introduced in the current Chinese seismic design code. To investigate the reliability of the current seismic design code, seismic fragility analyses were performed for 45 10-story reinforced concrete (RC) frame-shear wall structures designed according to the current Chinese seismic d...

The significance of incorporating soil-structure interaction effect in the analysis and design of RC frame buildings is increasingly recognized but still not penetrated to the grass root level owing to various complexities involved. It is well established fact that the soil-structure interaction effect considerably influence the design of multi-storey buildings subjected to lateral seismic load...

The work presented herein sets out to investigate numerically, by means of nonlinear finite element analysis, the effect of un-reinforced concrete or masonry infill walls on the overall structural response of reinforced concrete frames under static monotonic and seismic loading. For this purpose, a nonlinear finite element package purpose built for the analysis of concrete structures is employe...

Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...

Brick masonry veneer walls connected to infill inserted in a reinforced concrete (RC) frame are common constructive system Portugal. The stability of the wall is ensured by ties that make connection with walls. These enable transferring out-of-plane loads main structure due wind, and particularly earthquakes. However, characterization seismic behavior these tie connections an insufficiently exp...

Geopolymer concrete is preferred over OPC due to its use of energy waste such as fly ash, making it more sustainable and energy-efficient. However, limited research has been done on seismic characterization in confined masonry, highlighting a gap earthquake-resistant structures. Our study compares the performance alkali-activated fly-ash-based geopolymer bare frame masonry wall panels with conv...

In the last decade, displacement-based seismic design procedures have been recognised to be effective alternatives to force-based design (FBD) methods. Indeed, displacement based design (DBD) may allow the structural engineer to get more realistic predictions of local and global deformations of the structure, and hence damage, under design earthquakes. This facilitates the achievement of perfor...

an experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. the first specimen was a reinforced concrete frame with solid-brick infill. the second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. the last specimen was a reinforced concrete frame without any infill. these three specimens were tested by pseudostatic method. di...

Abstract The seismic behaviour studies of structures with RC frame show that the wall infill significantly improved lateral strength. However, since numerical analysis considers walls as non-structural components, rarely includes infills. It is strongly recommended in further research to investigate under load for having one important components their design process. This study developed two mo...
