Investigation Of The Effect Of Earthquake On Concrete Minaret Under Static Loads Using Genetic programing

Minarets are special structures commonly used in Islamic architectures. The seismic behaviors of minarets is quite different from that the other well known structures because of their unique structural characteristics such as slenderness, distinctive geometrical shape and support system. Post earthquake observations indicate that there is a direct relationship between site selection and overall minaret behavior and damage. This study investigates the seismic response of cylindrical concrete minarets with circular cross section under static loads using genetic programing. Using SAP 2000 software, considered minarets were analyzed. At the first phase of study, according to regulation of designing of structures against earthquake (regulation No.2800), minarets dynamic responses were determined by a hand-operated analysis. Seismic analysis were carried out considering the design spectra defined by Iran structure design codes in Naqan, Shahr-e-kord. On the base of hand-operated and SAP2000 calculations the shear base and maximum lateral displacements were estimated.
