The purpose of this study is to evaluate the flexural, vibrational, and fire resistance performance of void deck plate inserted omega type steel plate. Each of the series is composed of 1 existing steel wire integrated deck plate and 2 specimens which have variables about topping thickness. The result showed that there was not degradation of flexural performance by a void and vibration performance is equal or higher. Evaluation of fire resistance performance about 2 specimens which have same void is also satisfied with an appraisal standard. In conclusion, it is comprehended the void deck plate inserted omega type steel plate perform equal level with solid deck plate as well as reduce the amount of concrete effectively.
