3D FE Analysis of Shear Connector with Partial Interaction

What is it about?

A 3D body finite element model with multiple elements was counseled to simulate shear connector based on static loading. The behaviour of the steel in concrete connection will have the main significance of the global behaviour of the structural element. The geometry and material nonlinearities of headed stud, steel beam were included in the finite element model. Contact regions between the concrete and steel elements are simulated using surface-to-surface and embedment techniques. Resulted shear capacity for studs are compared with several codes of Practices such as EC4, AISC and BS and BS5950.

Why is it important?

The data for a load–slip curve of the shear connectors in composite structures are limited to data obtained from the experimental push-out tests. The proposed model was used to estimate the load-slip curve and to analyse important phenomena of the mechanical behaviour of connectors that are usually difficult to evaluate through tests, such as the distribution of stresses. It is demonstrated that after careful calibration against test data, the finite element models are able to predict the accurate result for the slip. The reliability of the model is checked against tests results and the numerical results for the load-slip curve were in good agreement with the test results
