A parameter optimization design method is proposed for multiple coal bucket dampers (CBDs) to reduce the seismic response of coal-fired power plants. To test the damping effect of the optimized CBDs, a 1 : 30 scale shaking table test model of a power plant structure was fabricated. A comparative testing program was conducted using three seismic excitations on a model with and without CBDs. A finite element analysis model, replicating the conditions of the shaking table test, was constructed for comparison, and the shock absorption effects of CBDs subjected to 22 groups of far-field seismic action and 28 groups of near-field seismic action were analyzed. Finally, the influence of changes in the structural period on the seismic response of the CBD-equipped structure was studied. The results indicate that the use of CBDs in a coal-fired power plant structure, based on an optimization design method for multiple-tuned mass dampers (MTMDs), results in a significant reduction in the structure displacement response, displays a certain discreteness under different excitations, and maintains a certain damping stability even as the structural period changes. Overall, the use of CBDs is a promising prospect for improving the seismic performance of coal-fired power plant structures.

The Impact

This research performed dynamic tests on a 1/4 scale test model of a new-styled Korean traditional wooden house to study its dynamic characteristics. The dynamic tests were performed both by the impact hammer test and the shaking table test of an El-centro N-S seismic wave. Together with these dynamic tests, structural analysis was also performed and the results were compared. The natural frequency from the impact hammer test was slightly higher than that from the shaking table test. The natural frequency from the eigenvalue analysis was about 16~33% lower than that from both the impact hammer test and the shaking table test. It can be deduced that the rotational stiffness of joints of analysis model were somewhat underestimated than those of experiment model.

History Of

This paper presents the nonlinear dynamic simulation analysis of a shaking table test specimen, which was a twelve- story reinforced concrete frame and tested under base excitations representing four earthquake records of increasing intensity. Owing to the length constraint of the paper, three cases are used for the simulation. The numerical simulation of the test model is conducted utilizing the finite element analysis procedure CANNY, and the analysis results include the natural frequency, response history of the frame and the damage evolution. It is concluded from comparisons between experimental results and the numerical simulation ones that the latter matches well with the former, therefore the validity of the analytical method and model for simulation of RC frame shaking table test is proved.

Similarity Ratio

Since the responses of Liquid storage tanks (LST) include the liquid motion, structural motion, and fluid-structure interaction (FSI) under the earthquake ground motion, it is a difficult problem about shaking table test model for satisfying similarity ratio requirement. The two experimental models, namely satisfied FSI similarity ratio model (FSI model) and unsatisfied FSI similarity ratio (un-FSI) model, respectively, are presented in this paper. The PCS storage tank of AP1000 Nuclear Power Engineering, as the study project, is studied by Adina software, and the responses, such as stress, stain, and displacement, etc., of prototype model, FSI model, and un-FSI model are compared. The results provide that when researchers study the rigidity LST dynamic response parameters and vibration characteristics, such as displacement, acceleration and liquid wave height, the tank wall stress response parameters etc., FSI model should be used.
