Abstract

U završnom radu je obrađena tema posmičnih naprezanja tankostjenih profila pri općem slučaju savijanja (savijanja silama). Prikazan je način određivanja posmičnih naprezanja i postupak određivanja položaja središta posmika za simetrične i nesimetrične poprečne presjeke. Riješeni su i numerički primjeri izračuna položaja središta posmika simetričnih i nesimetričnih tankostjenih otvorenih profila. U eksperimentalnom dijelu određeni su položaji središta posmika na primjerima tankostjenih otvorenih profila u laboratoriju i uspoređeni s teoretskim dobivenim središtima.

Abstract (english)

This thesis deals with the subject of shear stresses of thin-walled profiles in the general case of bending (force bending). The method of determining the shear stresses and the procedure for determining the position of the center of shear for symmetric and asymmetric cross sections are presented. Numerical examples of the calculation of the center of shear positions of symmetrical and asymmetric thin-walled open cross sections are also solved. In the experimental part, the positions of the shear centers were determined using examples of thin-walled open profiles in the laboratory and compared with the theoretically obtained centers.
