The first phase of the Alborz Observatory Array (Alborz-I) consists of 20\nplastic scintillation detectors each one with surface area of 0.25 m2\nspread over an area of 40\×40 m2 realized to the study of Extensive\nAir Showers around the it knee at the Sharif University of Technology\ncampus. The first stage of the project including construction and operation of\na prototype system has now been completed and the electronics that will be used\nin the array instrument has been tested under field conditions. In order to\nachieve a realistic estimate of the array performance, a large number of\nsimulated CORSIKA~ citea showers have been used. In the present work,\ntheoretical results obtained in the study of different array layouts and\ntrigger conditions are described. Using Monte Carlo simulations of showers the\nrate of detected events per day and the trigger probability functions, i.e.,\nthe probability for an extensive air shower to trigger a ground based array as\na function of the shower core distance to the center of array are presented for\nenergies above 1 TeV and zenith angles up to 60\∘. Moreover, the\nangular resolution of the Alborz-I array is obtained.\n
