- چکیده:
- چکیده انگلیسی: 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

- چکیده:
- چکیده انگلیسی: Widely distributed 111 series, 10 story R.C. frame buildings are constructed during former soviet union in Armenia and Nagorno-Karabakh province. In current research we illustrate the concept of seismic upgrading of above mentioned buildings, using an Additional Isolated Upper Floor (AIUF). For this purpose, a three dimensional of 111-c R.C. frame building is modeled and analyzed according to Armenian SNIP II-6.02 code, based on 3 soil categories of Rock (Vs>800m/s), Dense Soil (500
