“…In addition to being an excellent alternative to displacement-based and velocity-based damping mechanisms, the AR-Brace was designed to be an effective and inexpensive substitute for conventional crossbracing mechanisms. H. Mirjalali et al [12] studied the effect of bracing form on progressive collapse resistance of eccentrically braced frames in 2019. Results showed that the frame with two braced bays had more progressive failure resistance in specific element removal scenarios than the one with three braced bays under just gravity loads.…”

This paper presents cable bracing with a new configuration so that all cables remain in tension. For this purpose, a diamond cable bracing system comprising cables and rings is proposed for steel frames. The use of cable bracing is due to its advantages, such as high tensile strength and lack of buckling in evaluation with traditional braces. The proposed method can be installed easily for existing structures. Also, the cable is lightweight, and it has delicate dimensions. Sap2000 software was used to model the cables and rings. It was found that the proposed system eliminated the main weakness of the x-shaped cable bracing system. Increasing or reducing the diameter of the cables can control the displacement. Among the studied models, MRF has the least amount of axial force applied to the beams . A large amount of axial force is added to the floor beams by adding steel cable braces to the frame. In this case, by increasing the diameter of the cables, the amount of this force can be reduced.

“…Also as the number of bay and stories increases the progressive collapse resistance increases. The effect of bracing type and topology on progressive collapse resistance of eccentric braced frame was evaluated by Mirjalali et al [6]. Inverted and combined inverted V, Single and double diagonal eccentric braced frames were analysed in OpensSEES software by using nonlinear dynamic analysis.…”

Progressive collapse is a situation where local failure of a primary structural component leads to the failure of adjoining members, which in turn leads to spread of failure resulting in the collapse of an entire structure or disproportionately large part of it. In this paper, the effectiveness of inverted V type bracings on progressive collapse resistance of steel building is presented. 4-storey moment resisting steel frame building is considered for the study. Progressive collapse analysis is carried out under ten different column and/or bracing removal scenario from the ground floor level by following the U. S. General Services Administration (GSA) guidelines. Linear Static and Linear Dynamic analysis is performed to evaluate progressive collapse potential of 4-storey steel building considered for the study using SAP2000 software. Alternate Path Method (APM) is used to determine the Demand Capacity Ratio (DCR) of selected beam, column and bracing members located in surrounding of removed column. From the analysis results in terms of DCR of beams and columns, it is observed that the addition of bracing members, reduces the risk of progressive collapse.
