Abstract

The paper studies the reliability analysis and passive vibration control (PVC) of tall structures with uncertain parameters. A tall structure is modeled using certain parameters, Monte Carlo method is employed to create the uncertain parameters for the selected tall structure. The robust tune-able PVC (TPVC) schemes are installed to mitigate the response of the structure under earthquake excitations. Different tuned mass damper (TMD) schemes are used to mitigate the response of the structure. These schemes are single TMD (STMD), multiple TMDs (MTMDs), and distributed MTMDs (d-MTMDs). Newmark’s integration method is used to solve the equation of motion for the coupled system. It is found that ignoring the uncertainties in parameters of structure cause reduction in performances of the TPVC. Different probability distribution functions (PDF) are compared to select the most suitable one.
