Utjecaj veličine zidnog nosača na njegovu nosivost i duktilnost

Prikazani su rezultati proračuna utjecaja veličine zidnog nosača bez armature za preuzimanje posmićnih naprezanja na njegovu nosivost i duktilnost. Primijenjen je program za nelinearni proračun betonskih konstrukcija temeljen na metodi konačnih elemenata. Proračun je proveden za tri različita postotka armiranja na savijanje i pokazuje da se povećanjem dimenzija smanjuje nominalna nosivost i duktilnost. Ističe se da za inženjersku praksu pad nominalne nosivosti nije značajan.
Results obtained by determining, through shear stress analysis, the influence of size of wall girders without reinforcement on their bearing capacity and ductility are presented. The program for non-linear analysis of concrete structures, based on the finite-element method, was used. The analysis was conducted for three different percentages of reinforcement aimed at countering the bending action. This analysis has shown that the nominal bearing capacity and ductility reduce with the increase in size. It is stressed that this reduction of nominal capacity is not significant for engineering practice.
