The Comparison Analyses of Nonlinear Calculations of Flat Plate Systems With and Without Shear Reinforcement

Abstract

Linear, nonlinear and test comparison analyses of flat plate slabs with shear reinforcement are presented in the article. Analyses of slabs with and without shear reinforcement by nonlinear simulations are introduced. The calculations of slabs without and with 0.16 m eccentricities were performed. For analyses finite element method were used. Design models of flat slab with column by "Lira SAPR" software were carried out. After the calculations whole results with experimental investigations were compared. The comparison analyses were shown, that presence of shear reinforcement far increase the capacity of slabs. Furthermore, the presence of shear reinforcement depends on eccentricity increases the axial force approximately 25%. Moreover, the difference between tests and nonlinear analyses results are about 6.4%.

Comparison Analysis of Punching Buildings With Flat Plate Under Static and Seismic Loads

“…The appearance of the border differs from each other according to different construction norms. According to the Armenian and Russian reinforced concrete standards, the edge of the transverse section has a quadrangular shape (square or rectangular), and according to the European and American reinforced concrete standards, the appearance of the edge is curvilinear [3,4]. Borders in the shape of a rectangle or a square slightly deviate the actual calculations, but make further calculations quite easy.…”
