“…The rotational contribution to the translation, x m,φ and y m,φ , is found by a trigonometric relation between the rotation of the shared boundary, φ, and the actuator loading point position in the previous load step, x m (i À 1) and y m (i À 1), cf. Equations (7)- (8). Here, r m , is the distance from the shared boundary to the actuator loading point, cf.…”

“…For this application, the load bearing structure has been simulated in a numerical model, while damping fixtures has been tested experimentally e.g. elastomer , stud types and magneto‐rheological . However, to close the gap between full scale and material testing within the industry of wind energy, the hybrid simulation concept is implemented for a single component structure – referred to here as single component hybrid simulation.…”

This paper presents a quasi‐static hybrid simulation performed on a single component structure. Hybrid simulation is a substructural technique, where a structure is divided into two sections: a numerical section of the main structure and a physical experiment of the remainder. In previous cases, hybrid simulation has typically been applied to structures with a simple connection between the numerical model and physical test, e.g. civil engineering structures. In this paper, the method is applied to a composite structure, where the boundary is more complex i.e. 3 degrees of freedom. In order to evaluate the validity of the method, the results are compared to a test of the emulated structure – referred to here as the reference test. It was found that the error introduced by compliance in the load train was significant. Digital image correlation was for this reason implemented in the hybrid simulation communication loop to compensate for this source of error. Furthermore, the accuracy of the hybrid simulation was improved by compensating for communication delay. The test showed high correspondence between the hybrid simulation and the reference test in terms of overall deflection as well as displacements and rotation in the shared boundary.

“…Self-centering mechanism was adopted in combination with SSSPs to achieve seismic resilience (Chu et al, 2021; Lu et al, 2021). To further improve the energy dissipation capacity of SSSPs, different restrainers were adopted, such as reinforced concrete plate (Zhao and Astaneh-Asl, 2004), mortar plate (Hitaka et al, 2007), wood plate (Ito et al, 2011), steel plate (Deng et al, 2015) or steel-concrete composite plate (Lin et al, 2019). Due to the large stress concentrating at slit ends, fracture was thereby generated (Ito et al, 2011), which surely reduced the energy dissipation capacity.…”

To solve the fracture issue, one solution is to adjust the location of large stress away from link ends.…”

The steel slit shear panel (SSSP) with tapered links is one type of efficient energy-dissipating devices, with tapered shape of the links accommodating the bending moment demand when subjected to lateral shear deformation. To dissipate the maximum amount of seismic energy, full plasticity is expected to be developed. However, out-of-plane buckling, which is almost inevitable for thin plates, significantly reduces its energy dissipation capacity. This work aims to quantify the amount of energy dissipation of SSSPs with tapered links considering the effect of out-of-plane buckling. Quasi-static cyclic loading tests on five SSSP specimens with different design parameters are conducted, based on which the refined numerical model is built and validated. In estimating the energy dissipation, the effect of out-of-plane buckling needs to be considered. Otherwise, the estimated energy dissipation can be as much as over two times the tested value. To consider the effect of out-of-plane buckling, the index of average pinching parameter is adopted. A new method is derived for estimating the energy dissipation of SSSPs with considering the effect of out-of-plane buckling, feasibility of which is validated using the obtained test results.
