| Popis: | [EN] Headed studs are often used to facilitate composite actions between steel and concrete structures. In steel building structures, reinforced concrete walls are commonly used to ensure composite action to stiffen steel frames as a lateral resistance system against horizontal loads, such as earthquakes or wind. Such walls need to be anchored to the steel frame by headed studs, and these must be able to withstand shear and tension forces, as well as the interaction between these two. To design such anchors in concrete walls, it is necessary to describe experimentally their behaviour under monotonic and cyclic shear forces given that edge conditions and reinforcing details influence stud stiffness and strength. As very few experimental studies have examined headed studs subjected to monotonic or cyclic shear with usual boundary effects in steel frames with reinforced infill walls, a new experimental test setup and test results are presented herein. Four tests on headed studs were carried out to describe the behaviour of headed studs under monotonic and cyclic shear loading, as well as to validate the new test setup. This research shows that the behaviour of studs installed in infill walls without group effects are conservatively predicted by EC-4 and Makino's formula under monotonic shear loading. Furthermore, a reduction factor of 0.70 is recommended to design studs subjected to cyclic shear forces. The present study was supported by the Universitat Politecnica de Valencia (UPV) and the Spanish Ministry of Economy and Competitiveness through Project BIA2015-70651-R and Generalitat Valenciana (GVA) by BEST2018. The authors would like to express their gratitude to Debra Westall for revising the manuscript. |
