Seismic performance of column-bearing silo structure with granular materials considering SSI effect

Jinping Yang et al.

Summary: This study investigates the seismic performance of column-bearing concrete grain vertical silo structures considering soil-structure dynamic interaction (SSI), focusing on the effects of different silo height-to-diameter ratios, different storage categories, and different site soil categories. The results show that the SSI effect can reduce the absolute acceleration response in full silo models, with a slightly larger reduction at the top of the support column compared to the top of the silo. The SSI effect has the greatest damping effect on the absolute acceleration response when the silo is filled with wheat. Among the parameters studied, the height-to-diameter ratio has the greatest influence on the seismic response and hysteretic energy dissipation performance of the silo structure considering SSI effect, followed by the foundation soil.

Frequency independent damped outrigger systems for multi-mode seismic control of supper tall buildings with frequency independent negative stiffness enhancement

Meng Wang et al.

Summary: A purely frequency-independent negative stiffness damped outrigger (FI-NSDO) system is proposed in this paper, which combines frequency-independent damper (FID) and negative stiffness device (NSD). The FI-NSDO has the capability of simultaneously increasing the damping ratios of all target modes to their maximum values. Analysis in both frequency domain and time domain shows that the proposed FI-NSDO performs better in controlling the multi-mode vibration of seismic responses.

Experimental study on adaptive-passive tuned mass damper with variable stiffness for vertical human-induced vibration control

Liangkun Wang et al.

Summary: In this study, an adaptive-passive variable stiffness tuned mass damper (APVS-TMD) is proposed to solve the mistuning problem of a passive TMD. The stiffness and frequency of the APVS-TMD can be retuned by changing the length of the cantilever beam and adjusting the air gap between the conductor plate and magnets. Numerical simulation and experimental verification show that the APVS-TMD can accurately identify the decoupled structural natural frequency and effectively control human-induced vibrations.

Bi-directional semi-active tuned mass damper for torsional asymmetric structural seismic response control

Liangkun Wang et al.

Summary: In this study, a bi-directional semi-active TMD with adaptive stiffness, variable mass, and semi-active damping is proposed to improve the seismic protection performance. The BSTMD can adapt to X and Y directional frequencies simultaneously and reduce the stroke of unidirectional STMD. Numerical results show that the BSTMD has a comparable control effect with less electromechanical devices.

Seismic Response Control of a Nonlinear Tall Building Under Mainshock-Aftershock Sequences Using Semi-Active Tuned Mass Damper

Liangkun Wang et al.

Summary: This study investigates the control effect of a semi-active tuned mass damper (STMD) on nonlinear buildings under mainshock-aftershock sequences. The STMD is able to adapt to the nonlinear behavior of the structure in different time segments by adjusting its stiffness based on a wavelet transform algorithm, and enhance energy dissipation by switching its damping coefficient in real time. Results show that the STMD effectively controls the displacement responses and base shear of the structure, and performs better than the passive TMD in reducing plastic deformation and dissipating energy.

Seismic control of adaptive variable stiffness intelligent structures using fuzzy control strategy combined with LSTM

Han Zhang et al.

Summary: This study proposes a novel semi-active control algorithm for adaptive variable stiffness intelligent structures. The algorithm combines fuzzy control strategy with Long Short-Term Memory (LSTM) to mitigate structural responses under earthquake excitations. The algorithm predicts the displacement and velocity responses using LSTM neural network and uses the predicted results for fuzzy control to obtain active control forces. Genetic algorithm is used to optimize scaling factors of displacement, velocity responses, and control force. The results show that the proposed algorithm significantly improves the control effect compared to conventional fuzzy control strategy.

Optimum vertical location and design of multiple tuned mass dampers under seismic excitations

Baki Ozturk et al.

Summary: An efficient method for the vertical location and design of multiple tuned mass dampers (MTMDs) has been proposed to reduce the response of building structures under seismic excitation. The method uses optimization techniques to determine the location and parameters of each tuned mass damper (TMD), and takes into account the effects of multiple frequency peak regions. Experimental results have shown that the proposed method is effective in reducing the dynamic response of building structures.
