Resumo: | |||||||||||||
Steel-concrete composite structural systems are increasingly adopted in Brazil s construction industry. In these systems steel and concrete are used to create sections that behave in structurally efficient manner by utilizing steel s tensile strength and concrete s compressive strength. The purpose of this research is to evaluate the structural behavior of a Stub-Girder floor system, modified to improve the use of steel profiles in its manufacturing process. A numerical procedure is developed, based on nonlinear analysis through the use of the finite element method (FEM), employing the software ANSYS. To calibrate the numerical model, data from full-scale tests available in the literature were used in addition to a full-scale test carried out in the Structures Laboratory (Civil Engineering and Environment department, PUC-Rio). A parametric analysis was performed using several types of profiles available in the Brazilian market so that the modified stub-girder system could be evaluated regarding strength and stiffness. The constitutive models for concrete were shown to be coherent with laboratory results.
