“…For simplicity, the flange thickness is always determined by several times of the web thickness in design. Generally the flange-to-web thickness ratio is taken as 4.0 in the previous works [3]. The numerical results of Chen et al [12] also verified that the flanges are stiff enough as fixed web boundaries, given the ratio value of 4.0.…”

“…This kind of steel mainly has three levels of yield strength as 100MPa (or 120MPa), 160MPa, and 225MPa. They have large elongation ranging from 40 to 60% [3]. Figure 4 shows material test curves of BT-LYP100 and BT-LYP225 provided by Nippon Steel Corporation [18].…”

“…For a successful hysteretic damper, it must effectively translate forces developed in response to the structural motion and dissipate as much of the energy input as possible at locations. The SPD has already been applied to many civil structures to control seismic responses and damage of the main members [3][4][5][6], due to its advantages of simple configuration, easiness to repair and/or replace. A properly designed shear panel damper may be into plasticity prior to the main structure.…”

ABSTRACT:Recently shear panel dampers (SPDs) have been applied to building and bridge structures widely, showing good effects in seismic hazard mitigation as passive energy dissipators. The mechanism of SPDs for dissipating earthquake-induced energy is through inelastic shear deformation of the metal. This paper firstly gives a brief introduction to the new development of configuration and material of SPDs. Then two important issues, namely, web buckling and hysteretic behavior of SPDs are mainly addressed. Several structural parameters, which have influences on bearing capacity, ductility and energy dissipation capacity of SPDs, are also discussed, with regarding to web slenderness ratio, stiffness of stiffeners, and contribution of flanges. Additionally, various restoring models of SPDs, which is developed to be used in evaluation of seismic control structures, are also discussed together with their hysteretic behavior. Finally, application of SPDs in building and bridge structures is presented, pointing out the issues deserving further study and potential application to new field of civil engineering.

“…Besides the out-of-plane stiffeners, two other solutions were proposed with the aim of facilitating plastic failure instead of elastic buckling. The use of low-yield steel, as base material for the plates, was introduced in Japan [4]; and pure aluminium shear walls were proposed by DeMatteis [5]. In both cases the goal is to exploit the low yield capacity of the material in order to facilitate shear yielding.…”

Sheathed Light-Gauge Steel (LGS) shear walls are often used in structures as load bearing elements against wind and earthquake actions. The design of walls is often complicated by the lack of analytical methods for the evaluation of the strength and rigidity. Design by testing is a possibility if large numbers of identical walls are used; but in the usual case designers are limited by economic consideration to use configurations which were already tested. These limitations greatly reduce the potential of using LGS shear walls in practical applications. In this paper an analytical design procedure is presented for LGS shear walls sheathed with flat thin steel plates. The procedure, developed for the evaluation of the shear strength and rigidity of the walls, takes into account the fixing of the steel plate to the skeleton. The method is validated using both Finite Element Modelling (FEM) and experiments; comparisons show good accuracy when it comes to the evaluation of strength, but not satisfactory for the rigidity.

“…When shear panel dampers are installed into building structures, they are expected to partially divert the input seismic energy into the dampers and reduce the seismic response of the structures under strong earthquake loads effectively and economically and to improve the energy dissipation capacity of the buildings [1][2][3]. The researches regarding bridge structures are presently insufficient [4].…”

A shear panel damper using low-yield steel is considered as one of cost-effective solutions to reduce earthquake damage to building structure. In this paper, we describe the development of a shear panel damper with high deformation capacity, which is a necessary condition for it to be a bridge bearing. The development is based on the measurement of strain distribution of the shear panels under cyclic loading test. For the measurement, an image processing technique is proposed to use with the two-dimensional finite element method, in which a constant stress triangular element is employed. The accuracy of the measurement is validated by comparing with the results acquired by strain gauges. Various shapes of shear panels are tested in the experiment to obtain the relationship between the strain distribution and the deformation capacity. Based on the results of the experiment, the shear panel damper is improved to achieve high seismic performance with large deformation capacity.
