چکیده مقاله:
According to construction of industrial structures in developing countries, current research is carried out on Self Standing Reinforced Concrete Chimneys, which are a sort of special structures and is used in several types of factories. For this purpose, the 3D model of an existing Reinforced Concrete chimney of 80.0 m high and a diameter of 4.0 ~5.0 m in Armenia, is modeled and analyzed using spectral analysis procedure according to 4th revision of Iranian 2800 seismic code, taking into account the spectral acceleration level to Sa=0.4g. On the next step, the finite element model is analysed by the means of Time History Analysis method, using 3 pairs of accelerograms recorded on each soil categories of Rock (Vs> 750m/s), Dense Soil (375
