Özet

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.
