“…High-rise buildings are particularly susceptible to wind due to their slender shapes and low damping ratios. Hence, estimating and mitigating wind effects are crucial for wind and structural engineers [1]. The main wind resistance measures for high-rise buildings include structural control, mechanical vibration control, and aerodynamic optimization.…”

Set-back modification represents a dependable method to reducing the wind effects on high-rise buildings, but the flow mechanism and aerodynamic responses of set-back tall buildings have not been explored systematically. Using the square building as the benchmark model, six set-back building models with varying steps and sizes were chosen for numerical simulation in this study. The results of mean wind pressure and local wind force distribution, power spectral densities of base moment, flow field, and structural response of the proposed building models are compared and analysed using the Large Eddy Simulation (LES) technique. The results demonstrate that the aerodynamic performance of set-back tall buildings dramatically improved, with the actual optimization in the cross-wind direction being more significant. Generally, a single set-back measure can enhance the aerodynamic performance of high-rise buildings more effectively than a double set-back measure. The outcome of this study provides an aerodynamic design guide for set-back tall buildings.

Active structural vibration control techniques are effective ways to lessen undesirable vibrations that are caused by external disturbances such as earthquakes. This study uses an artificial neural network-based (ANN) controller to actuate an active tuned mass damper (ATMD) to attenuate the response of a scaled three-storey shear frame structure. The ANN controller has shown its ability to mimic the classical controller behavior with fewer sensors. The controller used in this study is trained using a database of controller force generated based on a linear quadratic regulator controller. The results show that the neural network algorithm successfully reduced the structural responses compared to those of an uncontrolled system.

“…With the construction of high-rise, large-span, and lightweight structures, the vibration problem of civil engineering structures under external excitation is becoming increasingly prominent, making vibration control an important part of structural design [1,2]. TMD vibration reduction technology is widely used in civil engineering vibration control because of its remarkable reliability and economy [3,4].…”

“…In short, the existing control design of distributed tuned mass dampers control of RC wall vibration has the following shortcomings: (1) it still lacks experimental verification of the effectiveness of applying distributed damped oscillator devices to control multimodal vibration of RC walls; (2) there is a lack of methods determining the parameters of distributed tuned mass dampers for vibration reduction in the target frequency band.…”

Distributed tuned mass dampers (dTMD) can effectively mitigate the broadband vibration of a structure. However, when the vibration frequency in question reaches several hundred hertz, traditional optimization methods represented by fixed point theory are difficult to apply due to dense modal density, complex boundary conditions, and vibration inputs. This paper proposes the minimax method based on modal damping to optimize the oscillator’s frequency. Two typical wall panel specimens are tested to evaluate the proposed method. The mode shape of the uncontrolled wall and the vibration mitigation effect of the stacked sandwich-damped TMD under single-point bidirectional excitation is tested. The correlation between the modal damping and the vibration mitigation effect is evaluated. The results show that the RC wall panel has a dense mode when the frequency of interest reaches 300 Hz and above; the distributed stacked sandwich-damped TMDs can effectively mitigate the vibration of the RC wall panel in the frequency range of 200~450 Hz; and that the idea of optimizing the frequency of dTMD based on modal damping is feasible.
