“…Utomo et al [11] carried out a finite element study on an innovative vertical steel pipe device strengthened by two trapezoidal plates attaching to the outside of the pipe and also three inner rings whose role was to stabilize the pipe cross-section. The rings were designed not to yield; however, the pipe and trapezoidal plates were designed to yield, owing to achieving an appropriate amount of energy dissipation.…”

Cable-cylinder bracing system is a novel system composed of two steel cables and a steel pipe installed in a frame center. This system exhibits several merits mainly due to its simplicity; however, it needs to be enhanced due to limited source of energy dissipation, caused by plastic hinges formed at the ends of the beam, turning up some inappropriate cyclic behaviors in the hysteresis diagram of the system and also rupturing of the cables in large drifts. Therefore, we suggest the use of replaceable devices made of steel quarter-rings; and we propose a couple of accurate, practical, and simple formulas to calculate steel quarter-rings thickness utilized as replaceable devices. These equations correspond to the number of plastic hinges formed in the device partially under the capacity based design method. Also, the validity of these formulas along with the design requirements of device geometric parameters is fully examined and discussed by conducting FEbased parametric studies. Then, through the addition of four curved yielding devices made of low-yield-point steel to a cable-cylinder bracing system, the performance of the proposed system subjected to cyclic loading is identified.Based on the results, the new enhanced system represents a cost-effective,

“…To make practical use of circular yielding damper systems in constructing structures, research was conducted in which various modeling was done on buildings with dampers. Various finite element models were used to investigate the effect of low-cycle fatigue on tubular dampers' performance (Utomo et al 2015). These models demonstrated that it is necessary to investigate the effect of low-cycle fatigue on dampers' performance.…”

Yielding dampers should be designed in such a way that before the main elements of the structure yield, they provide the possibility of energy absorption and consumption. Therefore, for the structure's basic design, the damper's behavior in pressure and tension should be known, and their effect on the stiffness and strength of the structure can be estimated with relatively simple relationships. The main purpose of this paper is to provide accurate analytical relationships for the behavior of tubular dampers in compression and tension under the effect of uniform loading. In this regard, firstly, the behavior of a circular yielding damper was evaluated based on validated numerical models in ABAQUS software. Then, analytical relationships that show high accuracy compared to the results of finite element modeling have been presented using linear and nonlinear analysis. Also, a new bolt and nut connection detail is provided to reduce the possibility of welding failure at the joints of circular dampers. The new detail has been tested at a full-size scale and has shown no failure at the weld, even at large displacements. In the end, the results of the experimental sample with the presented analytical relations have shown that the analytical relations are highly accurate.
