Simulação numérica do comportamento de conectores de cisalhamento formados a frio

Abstract

The shear connector is a device applied to the steel-concrete interface of composite structural elements, with the function of transferring efforts between the steel element and the concrete element, and vice versa. The U shear connector made up of a cold-formed profile is a low-cost alternative connector, however, more studies to understand its mechanical behavior need to be developed. In this sense, this work aims to numerically simulate the mechanical behavior of U-shaped shear connectors consisting of a cold-formed profile. The numerical model developed was validated with experimental tests from the literature. The results obtained were satisfactory and consistent with the experimental results, indicating that the developed model is capable of simulating the behavior of U-shaped shear connectors with a cold-formed profile.
