The aim has been estimating the level of seismic hazard for the site and developing the well-known Design Spectra for horizontal component to verify the performed seismic design of the building and preparing seismic rehabilitation process. At first, it was tried to recognize all the active faults around the sites. Secondly, by using the appropriate attenuation relationships and two methods for calculating seismicity parameter, direct and Kijko methods, the horizontal PGA values on the sites were estimated. These values obtained vary between 0.366g and 1.008g for 2%, 0.259g and 0.686g for 10%, 0.218g and 0.539g for 20% and 0.173g/0.387g for 50% probability of exceedence in 50 years ground motions depending on the applied attenuation laws such as Ambraseys, Ambraseys and Bommer, and Zare and Ashtiany. The more exact horizontal PGA values, obtained from mean of two mentioned methods, for 2%, 10%, 20% and 50% probability of exceedence in 50 years ground motions were 0.627g, 0.418g, 0.342g and 0.260g. Finally, the Newmark-Hall design spectra, which are more reliable for design purposes, were constructed for the 2%, 10%, 20% and 50% probability of exceedence in 50 years ground motions. The 10% and 2% spectra (first and second hazard level) compared with Iranian Standard Design Spectrum and 1.5 times of this spectrum respectively. This comparison showed that the values of Newmark-Hall design spectra are usually more than values of Iranian Standard Design Spectra.
