| Kangavar city is located at Kermanshah province west of Iran and northern part of Zagros Mountains. Zagros is known to be the most seismic region in Iran. Thus, seismicity and geotechnical micro-zonation of Kangavar are set the goals of this research. To do this, firstly, following a probabilistic seismic hazard analysis the peak ground acceleration and spectral acceleration on seismic bedrock is elaborated using the CRISIS2007 software. Secondly, to investigate the site conditions series of microtremor measurements at 15 points in the vicinity of the city is carried out and the natural frequency map and shear wave velocity profile for the ground are determined using Geopsy software. This should note that the thickness of the alluvial is small in northern part of the city. Furthermore, the results of electrical resistivity tests are used to investigate the alluvium depth and discontinuity in ground profile. This analysis confirmed the existence of thicker alluvial in southeast part of the city. Finally, according to all findings of this research a general recommendation for urban planning and future building and construction is proposed according to Iranian national code for earthquake resistant buildings, as a function of three variables; Geo-hazards type, Importance, and lateral resistant structural system. | ||
