Transverse Vibration Control for Cable Stayed Bridge Under Construction Using Active Mass Damper

Vibration Control of a Power Transmission Tower with Pounding Tuned Mass Damper under Multi-Component Seismic Excitations

In this paper, the two-dimensional vibration controls of a power transmission tower with a pounding tuned mass damper (PTMD) under multi-component seismic excitations are analyzed. A three-dimensional finite element model of a practical power transmission tower is established in ABAQUS (Dassasult Simulia Company, Providence, RI, USA). The TMD (tuned mass damper) and PTMD are simulated by the fi...

The Effect of Tuned Mass Damper on Seismic Response of Building Frames with Uncertain Structural Characteristics

Tuned mass dampers (TMDs) could be used to absorb the input energy of the applied load, and reduce the response of the building frames. However, the effectiveness of TMD in reducing the response of the building frames could be affected by inherited uncertainties in the structural characteristics of the frames. In this study, in order to investigate the probabilistic response of steel moment-res...

A RELIABILITY APPROACH TO COMPARE OPTIMAL SEISMIC DESIGNS OF MULTIPLE-TUNED-MASS-DAMPER

Passive systems are preferred tools for seismic control of buildings challenged by probabilistic nature of the input excitation. However, other types of uncertainty still exist in parameters of the control device even when optimally tuned. The present work concerns optimal design of multiple-tuned-mass-damper embedded on a shear building by a number of meta-heuristics. They include well-known g...

Application of Structural Damage Control in Seismic Performance Opti- mization of Long-span Cable-stayed Bridge

The damage caused by earthquake is irresistible for human beings, and the structure with poor robustness is most affected by earthquake. Especially when traffic arteries like bridges and highways are affected, the losses will be unimaginable. To reduce the loss in earthquake, the paper targets the long-span cable-stayed bridge and discusses a method of structural damage control. The energy-diss...
