“…Gioncu and Mazzolani (2014) indicated the most universal typology of lateral excitation resistant steel frame for concentrically braced frames and the compression diagonal in X-bracing is typically to be neglected among the weak points in the design [7]. A high elastic stiffness and strength are the characteristics which in the chevron braces [13]. Chevron also effectively in the architectural functionality.…”

“…However, the tension braces remain in tension while the braces in compression lost all the axial load capacity after buckling. This contributes to the unbalanced distributed lateral load and caused large bending moment in the intersection of beam and braces [13]. This leads the mid span beam undergoes the plastic hinge and collapse due to unable to sustain the downward forces [10].…”

“…The AICS Seismic Provision have suggested that using a strong beam which is able to provide adequate strength such as deep and heavy beams to prevent the undesirable deterioration of frame [13,15]. This means that the strong beam mechanism is higher in the ductility and energy dissipation to delaying the braces fracture since the chevron is nonductile behaviour [12,15].…”

“…This arrangement is known as the zipper braces frame (ZBF). The struts mitigate the vertical load induced to the adjacent story braces and keep their axial load capacity after compression braces buckled [13]. Besides, the struts help to redistribute the loads on each storey.…”

“…Besides, the struts help to redistribute the loads on each storey. Besides that, the strut helps to redistribution the loads on each stories and contribute to the redistribution of deformation demands [12,13]. This caused to inelastic action along the height of frames and demand of uniform drift.…”

Abstract. Excessive lateral drift can contribute significantly towards crack formation, leading to structural damage. The structural damage will in turn reduce the capacity of the structure and weaken it from the intended design capacity. Generally, lateral drift is more pronounced in higher and longer structure, such as high rise buildings and bridges. A typical method employed to control lateral drift is structural bracing, which works by increasing stiffness and stability of structure. This paper reviews the influence of various types of structural bracing to structural performance of buildings. The history of structural bracing is visited and the differences between numerous structural bracing in term of suitability to different types of buildings and loading, mechanisms, technical details, advantages and limitations, and the overall effect on the structural behaviour and performance are dissected. Proper and efficient structural bracing is pertinent for each high rise building as this will lead towards safer, sustainable and more economical buildings, which are cheaper to maintain throughout the life of the buildings in the future.

In this paper, an innovative damper made of low yield point (LYP) steel compound of double corrugated plate and flange plates to form an I‐shaped damper was considered parametrically and numerically. This damper pertain to easy fabrication and replacement after a severe earthquake. The proposed damper is expected to yield while elements outside the damper remain elastic. Consequently, it acts as a ductile fuse that was confirmed in this study. Results indicated that changing the damper from conventional steel to LYP steel improves the damper's performance. Because dampers with the same exhibited different responses, classification of the damper response based on the is not approritae. Of course, considering the fact that it has shear behavior with can be used in the initial design, but it is an incomplete criterion. Also, for dampers with , the ultimate strength is increased related to the from 2.64 to 4.50 times whereas for and is reached 1.35 to 3.84 times and 1.34 to 3.80 times, respectively. It confirms that on the , the most effective on the ultimate strength is obtained by changing the A36 steel to LYP steel. It should be noted that by increasing the by two to four times, the energy dissipation is enhanced 1.44 to 5.64 times for LYP dampers and 1.15 to 2.02 times for A36 dampers.
