  7. Abstract:
  8. Prestressed concrete structures are used all around the world widely; especially for elements which are under the effects of bending like prestressed concrete slabs. In these sorts of elements the aim of designing is to control the tensional stresses and the cracks delivering higher strength. This can improve the capabilities of the structure, architecturally and economically. Seismic design of structures is based on horizontal component of ground motions. In recent years, it has been observed that the vertical component of ground motion could be stronger than horizontal one especially for those which have happened in near field sources. In these kinds of earthquakes the importance of vertical component is dramatically high even the vertical to horizontal acceleration (V/H) ratio is much higher than assumed before (2/3rd). In this study the effects of vertical component of ground motion on prestressed concrete beams is investigated. Then discuss the advantages of prestressed concrete structures because of its behavior due to earthquake. It is obtained that for near field earthquakes, according to code although the design satisfies the code limitations, but the beam will collapse under load combinations. Finally delivering an ordinary design criteria to use for prestressed concrete elements, with the least expense
