Steel braced frames are commonly used in steel structures to control and improve the seismic performance of under severe lateral forces such as an earthquake. So, providing better formability would help designers achieve their desire level. This study is focused on utilizing curved dampers ductile frame instead using knee elements provide energy dissipation, strength, elastic stiffness during c...

This paper examines the seismic behaviour of steel Multi-Tiered Concentrically Braced Frames (MT-CBFs) Conventional Construction category (Type CC) in moderate regions eastern Canada and proposes a new design method for such structures. A total 32 prototype MT-CBFs part single-storey building are selected designed accordance with 2019 Canadian standard (CSA S16-19) provisions Type CC structures...

Unpredicted loading caused by blast or impact may lead to severe damage in structures. Such damage may affect the whole structural performance. Connections are the key contributor to the integrity and energy dissipation capacity of the structural steel systems and play the most important role in mitigating such consequences. In the view of the importance of connections, finite element analysis ...
