In order to validate the seismic performance of precast concrete members with steel sleeve connections, pseudo-static tests on four prefabricated columns with vertical grouted splice sleeve connections and on a control group of two cast-in-situ columns have been conducted. The test results indicated that the failure modes of the prefabricated columns and of the cast-in-situ columns are basically identical but differences exist in their crack distribution. The cast-in-situ columns mainly crack horizontally at the bottom of the column, whereas the prefabricated columns have horizontal cracks above the sleeves, and then form diagonal cracks downwards and develop many wider cracks within the range of height of 300 mm at the bottom of the column. The hysteresis curves of the prefabricated columns are plump, which demonstrates that prefabricated columns have satisfactory energy-dissipating capacity. Moreover, the stiffness degradation of the prefabricated specimens is slower than that of the cast-in-situ specimens. The ultimate displacement angle of the prefabricated columns is up to 1/104–1/54, which satisfies the requirements of the inter-story drift ratio during major earthquakes. Finally, some recommendations on practical seismic design pertinent to the precast concrete members with grouted splice sleeves are proposed.

This paper investigates the dynamic behavior of structures with a particle damper (PD) and a tuned mass damper (TMD) by shaking table tests and aeroelastic wind tunnel tests. The influence of parameters including seismic waves, peak ground accelerations, damping ratios, mass ratios, and wind angles of attack are analyzed. A systematic comparison between the PD and TMD shows that the vibration-control effects of the PD are generally better than those of the TMD under both earthquake and wind loads. The reason lies in the fact that the PD can dissipate the input energy not only by tuning frequency (similar to TMD) but also by the impact and friction between particles and between the particles and the wall of the container. Moreover, a theoretical analysis of a single-degree-of-freedom (SDOF) system with optimum PD and TMD was also carried out by numerical simulations, and the hidden vibration-control mechanism is discussed. The results indicate that the optimum vibration-control effects of both dampers are comparable, but the swing amplitude of the additional mass of the PD is much smaller than that of the TMD. Through a series of experiments with various parameters, the results demonstrate that the characteristics of the seismic input and the wind angle of attack have a larger influence on the damping performance of the TMD compared with the PD, indicating that the PD is less sensitive to the changing parameters.
