Structural systems often show nonlinear behavior under severe excitations generated by natural hazards. In that condition, the restoring force becomes highly nonlinear showing significant hysteresis. The hereditary nature of this nonlinear restoring force indicates that the force cannot be described as a function of the instantaneous displacement and velocity. Accordingly, many hysteretic restoring force models were developed to include the time dependent nature using a set of differential equations. This survey contains a review of the past, recent developments and implementations of the Bouc-Wen model which is used extensively in modeling the hysteresis phenomenon in the dynamically excited nonlinear structures.

“…Hysteretic steel damper is a passive damper system that absorbs substantial portion of input energy induced by earthquake through hysteretic deformation of the damper material. In the past 20 years, a number of innovative hysteretic steel dampers with high energy dissipation capacity have been proposed and tested, such as Tadas device [10][11][12], ADAS device [11,13], honeycomb damper [14], shear panel [15,16], rhombic ADAS [17,18], dual-function DFMD [19], slit damper [20][21][22], buckling restrained brace [23,24], tube-in-tube damper [25], and circular plate damper [26]. Figure 1 shows several shapes of hysteretic steel dampers.…”

This study aims to evaluate energy absorption capacity of hysteretic steel damper for earthquake protection of structures. These types of steel dampers are fabricated from mild steel plate with different geometrical shapes on the side part, namely, straight, concave, and convex shapes. The performance of the proposed device was verified experimentally by a series of tests under increasing in-plane cyclic load. The overall test results indicated that the proposed steel dampers have similar hysteretic curves, but the specimen with convex-shaped side not only showed stable hysteretic behavior but also showed excellent energy dissipation capabilities and ductility factor. Furthermore, the load-deformation relation of these steel dampers can be decomposed into three parts, namely, skeleton curve, Bauschinger part, and elastic unloading part. The skeleton curve is commonly used to obtain the main parameters, which describe the behavior of steel damper, namely, yield strength, elastic stiffness, and postyield stiffness ratio. Moreover, the effective stiffness, effective damping ratio, cumulative plastic strain energy, and cumulative ductility factor were also derived from the results. Finally, an approximation trilinear hysteretic model was developed based on skeleton curve obtained from experimental results.

“…It is obvious that rhombic steel plate damper made by regular Q235 steel has a better bilinear property, while LYS damper, especially LYS160, reflects obvious strain hardening effect. Therefore, the skeleton curve of force-displacement relationship no longer satisfies bilinear behavior and its skeleton curve model is relatively complex, and the damping force model of LYS is investigated and put forward [16]. Comparison between the theoretical value computed by simplified bilinear model shown in (1) and the testing value of elastic stiffness, postyielding stiffness, and plastic yielding strength is shown in Table 2.…”

“…This new damper is made up of two triangular steel plates by edge-to-edge connection. Shih and Sung [16] proposed a modified Wen's model by considering nonlinear strain hardening characteristics of low yield strength steel under the circle reciprocating loading. Comparing the results of numerical simulation and experiment testing, it was shown that the modified Wen's model can closely reflect the hysteretic behavior of the rhombic steel plate damper.…”

Rhombic mild-steel plate damper (also named rhombic added damping and Stiffness (RADAS)) is a newly proposed and developed bending energy dissipation damper in recent years, and its mechanical properties, seismic behavior, and engineering application still need further investigations. In order to determine the basic mechanical performance of RADAS, fundamental material properties tests of three types of mild-steel specimen including domestically developed mild-steel material with low yield strength were carried out. Then, a quasistatic loading test was performed to evaluate the mechanical performance and hysteretic energy dissipation capacity of these rhombic mild-steel dampers manufactured by aforementioned three types of steel materials. Test results show that yield strength of domestically developed low yield strength steel (LYS) is remarkably lower than that of regular mild steel and its ultimate strain is also 1/3 larger than that of regular mild steel, indicating that the low yield strength steel has a favorable plastic deformation capability. The rhombic mild-steel plate damper with low yield strength steel material possesses smaller yield force and superior hysteretic energy dissipation capacity; thus they can be used to reduce engineering structural vibration and damage during strong earthquakes.
