The on-line test is regarded as an appealing alternative to the shaking table test. The versatile on-line testing system based on quasi-static loading jacks is introduced, and its advantages over the conventional on-line test systems in which servo-hydraulic actuators are employed are discussed in terms of the hydraulic capacity, portability, and robustness. The on-line testing system is applied to the earthquake response simulation of a three-story steel frame equipped with slitted shear panels that are stiffened by wood panels. The prototype structure, the target structure, and, the tested structure are noted, and its earthquake responses are presented in two levels of ground motion. It is disclosed that the tested dampers perform satisfactorily in the energy dissipation, and the merit of using such dampers in the enhancement of seismic performance of steel frames is discussed. Difficulties in substructuring are also noted in light of the complexity of testing and treatment of boundary conditions.
