Shear friction between the steel base plate and base mortar contributes to the shear resistance of standard column bases. A value of 0.5 is adopted as the coefficient of shear friction in All's design specifications, but the associated background data are limited. To investigate the dynamic shear resistance behavior between the base plate and mortar, a shake table study is undertaken using a large rigid mass supported by steel contact elements that rest on mortar surfaces fixed on the shake table. Horizontal input accelerations are considered for various magnitudes and frequencies. The results provide a constant friction coefficient during sliding with an average value of 0.78. Comparisons with previous test and numerical analysis are also carried out, and good correlation among them is noticed.

Peer-to-Peer Internet online hybrid test system is one of the appealing hybrid test systems developed recently and has been demonstrated to be valid and capable of handling multiple numerical nonlinear substructures. However, its feasibility to accommodate multiple tested substructures had not been applied. To explore this possibility, a one-bay four-story steel planar moment-resisting frame is analyzed. Two column bases of the frame are taken as the tested parts, while the superstructure is analyzed by ABAQUS. The three substructures are distributed to three different locations and connected through Internet. The plastic rotations of the two column bases are treated as boundary displacements. The system run successfully without any malfunction, and the concurrent implementation of the two tested substructures is found effective. The feasibility and stability is demonstrated for the Peer-to-Peer system to handle multiple tested substructures involving significant deterioration of resistance in part of the structure.

A significant amount of research has been done in order to evaluate and improve the seismic performance of the lateral load resisting system in building structures; however, there still exists a need to study the behavior of non-structural systems during an earthquake. In order to address this issue, shaking table tests were performed to look at the behavior of non-structural gypsum board partition walls typically found in steel frame structures. Both a traditional Japanese hanging ceiling system and a seismically designed hanging ceiling system were also studied. The results suggested that the non-structural partition walls undergo a rocking behavior when perpendicular walls are framed into them. In general, stiffness and damping values were large enough to affect the overall behavior of a structure. Both types of hanging ceiling systems sustained only minimal damage and performed as designed. However, the seismically designed ceiling system underwent large accelerations due to pounding with the partition walls at drift levels greater than 1/66 radians.
