RC STRUCTURE DESIGN IN ACCORDANCE WITH EN AND ASSESSMENT OF SEISMIC RESPONSE BY PUSHOVER ANALYSIS

Abstract

In this paper, in the first step, a linear-elastic analysis of the structure acording to Eurocode is carried out, internal forces of elements are determined, sections are designed, the displacement of the structure are cheked and reinforcement details are defined to ensure the assummed value of the ductility of the structure. This part of the calculation is carried out in the „Tower 8“ software. With such defined reinforcement details, a nonlinear static - Pushover analysis is carried out. A nonlinear model is formed, the load capacities of the plastic hinges are defined with previoulsy assumed position, load capasity for horizontal loads, and then deformation capasity is determined. In particular, gradual emergence of plastic hinges, the evolution of the plastic mechanism,  estimationof target displacements and determination the capacity curves. Nonlinear static analysis was carried out in the Etabs 18 software.
