In this study, the performance, dynamic
response and slab vibrations of the horizontal and vertical bearing elements
and floors, which constitute the engineering structures under earthquake hazard
today, were investigated. In addition, repair and reinforcement procedures are
also discussed in order to minimize floor vibrations caused by earthquake effects
on existing steel structure members. The results have been discussed for comfort
and fitness level of people by Turkey Building Earthquake Regulation the
proposed non-linear time history analysis done. The findings obtained for the
vibration of the floors are discussed and some design methods have been
proposed to minimize the problems of ground motion vibration. In this study was
examined a two story of steel structure that serving as a restaurant. By
analyzing the designed steel structure on the time domain, it was found that
the floors vibrate more than the vibration limit values recommended by the
regulations. These vibrations were tried to be minimized by increasing the
stiffness of the floors of the steel structure. However, the columns of the steel
structure were supported with diagonal elements and analyzed again. It was
determined that the damping rate of the steel floors increased and their
vibrations decreased through the reinforcement processes. It has also been
observed that the steel structure has reached a controllable damage level. It
has been suggested that the slabs should be connected to the main carrier beams
in a fully rigid manner in order to minimize the vibrations of the steel
floors. However, if the floors are not rigidly mounted on the main carrier
beams, it has been suggested that the columns should be supported with plastic
hinged diagonals at both ends.
