Study shear behavior for stud-groove connector in timber-concrete composite structure
(2018) 2018 World Conference on Timber Engineering, WCTE 2018- Abstract
Timber-concrete composite structures (TCCs) are widely gaining interest in Europe and America, because of its high strength and low energy-consumption structure. The key design point of timber-concrete composite structures are to ensure the reliability of the shear connectors. The objective of this paper was to predict structural response with finite element (FE) analysis and provide shear property of stud-groove-type connectors in TCC structures. In this paper, some experiments were done to provide the material property of timber and concrete, then the finite element model was built with the software ANSYS to analyze the connector property of the timber-concrete composite structure with interlamination slips. Additionally, push-out... (More)
Timber-concrete composite structures (TCCs) are widely gaining interest in Europe and America, because of its high strength and low energy-consumption structure. The key design point of timber-concrete composite structures are to ensure the reliability of the shear connectors. The objective of this paper was to predict structural response with finite element (FE) analysis and provide shear property of stud-groove-type connectors in TCC structures. In this paper, some experiments were done to provide the material property of timber and concrete, then the finite element model was built with the software ANSYS to analyze the connector property of the timber-concrete composite structure with interlamination slips. Additionally, push-out tests with different parameters (stud diameter, stud length, groove width, and groove depth) were tested to obtain the shear capacity and slip modulus of stud-groove connectors and validate the correction of shear strength from the finite element model. This study indicates that the shear capacity and slip modulus of stud-groove-type connectors was in direct proportion to the diameter of studs and the dimension of the groove. The finite element analysis can predict the shear strength of the stud-groove connector in a satisfying way.
