![]() Tuned mass dampers were also designed as a back-up vibration control system. Three-dimensional computer models of the structure were created and various modifications were made to the original structure, designed based on static loads, to reduce the possible excessive floor vibrations when subjected to walking excitations. This paper provides details of the vibration analysis and design of a novel office building. This is mainly due to decrease in the system mass resulting from the use of higher strength materials use of computer-assisted design and the Load and Resistance Factor Design Method to optimize the structure based on the strength requirements fewer partitions and more innovative designs by architects achieving long, column free spans resulting in a reduction in the natural frequency and damping. ![]() Annoying building floor vibrations have become a serious serviceability issue.
