Synopsis : 

The presented manuscript is intended to introduce accurate computational benchmarks to predict the hysteresis behavior of beam-column steel connections by means of a 3D non-linear finite element analysis.In this study, element type, inelastic material behavior,bolts pre-tensioning, and contact properties between different components of connections are discussed. Incremental nonlinear analysis takes into account all three types of nonlinearities including material, geometry, and contact properties in predicting moment-rotation hysteresis loops. A series of full-scale structural tests are performed to validate the results obtained from the finite element analyses. This study shows that cost efficient numerical analysis simulation is capable of replacing full-scale tests for steel connections.
