Controlled rocking of steel braced frames has been proposed for the seismic retrofit of structures. The controlled rocking approach allows a frame to uplift from its support at the base-of-column to foundation interface while displacementbased steel yielding devices are implemented at the base location to control the response. Past studies have focused on analytical investigations of the respon...

Abstract—This paper focuses on parametric analysis of reinforced concrete structures equipped with supplemental damping braces. Practitioners still luck sufficient data for current design of damper added structures and often reduce the real model to a pure damper braced structure even if this assumption is neither realistic nor conservative. In the present study, the damping brace is modelled a...

Displacement-based methods are recognized as appropriate approaches to reach the goals of performance-based seismic design method. In the direct displacement-based seismic design method, the seismic yield displacement is applied as one of the important design parameters. In this paper, a new relation is suggested to determine the lateral displacement pattern at first yielding of eccentrically b...

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...
