| Abstract |
The story height of the tall buildings is the significant factor due to the limited construction area within the central city such as Seoul. Therefore we developed iTECH(Innovative Technical Economical & Convenient Hybrid) system to reduce story height. Since the top flange of the proposed beam is within the slab, the vibrational characteristics have to be verified by the test. The purpose of this paper is to study on vibration characteristics of floor with iTECH composite system and to evaluate the serviceability. In this research, natural frequency, damping ratio and peak acceleration were measured at experiments for each construction step such as steel erection stage, concrete casting stage and finishing stage. The test results are compared with that of the code. As a result, the proposed composite slab showed enough vibrational characteristics. |
