The seismic-resistant structure is required for the earthquake-hazard area. One of systems Concentrically Braced Frame (CBF), which was established to diminish seismic damage. At time implementation, CBF reduces horizontal deformations building so that failure as well heavy damage can be avoided. In CBF, brace energy dissipator, whose performance needs enhanced. This study discussed structural ...

In the present study, friction damper, an energy dissipating passive device is explored to reduce response of open ground storey building under lateral loading due earthquake. This damper installed in selected bays so that reduced. The masonry infill wall macro-modeled form compression only diagonal members. Three different types bracing system were along with Pall – single tension brace cross ...

The design of steel chevron-braced frames as per Eurocode 8 is based on the idea that only braces should buckle and yield during ground motions, while other members remain elastic. elastic braced also allowed. However, in both cases, seismic performance frame may be compromised because premature yielding/buckling columns. This paper proposes an alternative procedure promotes yielding beams addi...

Yielding elements (YE) are among those devices that not only help control structural damages, but make better seismic behavior by concentrating the frames in some removable part of the structures. YE are located at the intersection of Concentric Braced Frame (CBF) in a rectangular shape. In this paper, Seismic behavior of the frames with YE will be investigated. For this reason, 5 braced steel ...

Conventional concentrically-braced frame (CBF) systems have limited drift capacity before brace buckling and related damage leads to deterioration in strength and stiffness. Self-centering concentrically-braced frame (SC-CBF) systems have been developed to increase drift capacity prior to initiation of damage and minimize residual drift. SC-CBFs differ from conventional CBFs in that the SC-CBF ...

In this paper, we propose an assembled self-centering buckling-restrained brace (ASCBRB), which eliminates the residual drift of structures after a major horizontal displacement. The ASCBRB also represents advanced device for partial replacement damaged parts brace. Four groups prestressed disk springs and metal yielding core plate were used to improve resilience energy dissipation brace, respe...

In this work, analytical pushover curves for concentric braced steel frames with active tension diagonal bracings (X-CBF) are proposed. A “spindle”, characterized by two trilinear capacity defined an X-CBF system subjected to prefixed lateral forces distribution, is defined. The able grasp the elasto-plastic behavior of X-CBFs. reliability proposal verified a series numerical comparisons obtain...
