Fiber takviyeli beton döşemenin doğrusal olmayan zımbalama davranışı üzerine parametrik bir çalışma

Abstract

This paper investigates the effect of fiber on the behavior of punching shear slabs; a finite element modeling approach is used to simulate the case study. The proportion mix of hybrid fiber-reinforced concrete, which contains 0.2 percent macro synthetic fibers and 0.68, 0.8, and 0.96 percent steel fibers, compressive strengths of 50 MPa, different longitudinal reinforcement used, and slab thicknesses of 150, 200, and 250 mm are all joined and investigated in this study. The ATENA software is used to perform nonlinear finite element analysis. The slab results validation was done similar to previous experimental work and the acquired results indicated that a great agreement was found. Thirty-six specimen two-way slabs with dimensions of 1900 × 1900mm were modeled in this investigation. All four sides of the slabs are simply supported. The results displayed that the ultimate shear capacity of the slabs increases with hybrid steel fiber. Nevertheless, the ultimate capacity of the slabs has decreased due to an increase in the reinforcement ratio and slab thickness.
