In design and construction of reinforced concrete flat plate slabs, consideration of opening for passing and traversing of installation pipes, ventilation, heating, air condition and electrical ducts is often necessary and inevitable. It has been made much experimental researches regarding effects and influences of opening on strength reduction and its effect on slab deflection, but for economical reasons such experiments have been restricted. In this research, in order to make prevalent the influence of openings (geometric figure and distance of opening from column) slabs having holes with various dimensions, which located in different distances from face of the column, have been analyzed by ANSYS software. Also, the results of these analyses have been compared with experimental results done by some other researchers, in order to review and deliberate these consequences and in case of conforming and adapting these results with fulfilled analyses, it can be achieved a set of considerable, general and comprehensive conclusions
