Since the design to resist the static loads resulted in low natural frequencies, it was believed that the structure is susceptible to large vibrations. A computer model for the vibration analysis and various design modifications was created. In addition, it provides the details of the structural analysis and design of a monumental stair located in an art museum. This paper presents a brief overview of the past research on the issues related to the vibration serviceability of staircases. This has resulted in structures with low natural frequencies and effective mass, which may become susceptible to large levels of vibrations. In recent years, a trend has appeared in architecture to design monumental stairs with slender structural components and few supports. In extreme cases the large movements of a stair may promote the feeling that the structure is not safe. Walking or running up and down a stair may result in vibrations that can be annoying to people.
