Abstract

The structures with the same frame system (flat plate), but with different spans (6 m and 7 m) and slab thicknesses (20 cm, 22 cm, 25 cm and 40 cm), static and seismic calculation was carried out by the finite element method using “LIRA SAPR”and “ETABS” software packages. Design of structure in accordance with Armenian building codes were implemented. In order to analyze the results of calculations, comparative graphs and tables with a number of variables were built. From the results of the analysis it became clear that the average value of punching shear is 14,58 %, and the average difference of the shear reinforcement area is 38,7%. Consequently, the anchorage length also should be checked by the American building standards for structure design.
