microalloyed s355n steel plates are extensively used in bridge and high-rise building structures. one ofthe factors affecting the mechanical properties is the size and morphology of inclusions. in this research,microalloyed s355n steel plates with different sizes of inclusions were examined. one contained longmanganese sulfide inclusions (li material) and the other had short ones (si material)....

Steel structures are second most numerous in the stock of existing buildings. In contrast to dominating concrete buildings, they typically lightweight and more sensitive alterations use or loads. While sustainability principles require maintain keep using these structures, structural assessments often indicate insufficient reliability need for replacements. The submitted contribution shows that...

Concrete columns confined with high-strength fiber reinforced polymer (FRP) composites can enhance the strength as well as the ductility of such structures. In recent years, the use of FRP composites to repair and strengthen existing reinforced concrete (RC) structures has been widely used. When the columns of existing RC structures are wrapped with FRP composites, the core concrete of such col...

An innovative lateral force resisting system is investigated that allows steel braced frames to uplift and rock on their foundation, partially isolating the frame. Passive energy dissipation devices are implemented at the uplifting location to control the rocking response to within allowable limits. The structure’s gravitational forces provide an inherent restoring force during the rocking resp...
