The analysis results indicated that the bending capacity of the corner column connections decreased with D / t and n increase but increased with h / b increase. In addition, the coupling effect degraded the bearing capacity of corner column joints, which was most significant at a loading ratio...
Conventional beam-to-column connections are either rigidly welded or bolted, or combination of both. Although both types of connections have high rotational stiffness and load-carrying capacities, the on-site welding quality is vulnerable to the impact of the surrounding environment and human factors,...

The connections of the columns to the foundation are rigid. Simulations were performed using OpenSees software for modeling of the beams and columns, and the nonlinear beam-column element with the plasticity in the length of element (with five integration points along the element) and fiber cross...
In this study, behavior of box beam-to-column connections with/without continuity plates, with external stiffener in two states with/without concrete (CFT/HSS) inside the column and finally reinforced connection by horizontal bar mats in CFT (Concrete Filled Tube) column have been studied by ...
Tests are described in which short, rectangular steel columns filled with concrete are loaded to failure under axial load. Part of the load is applied at typical beam connections within the column length; and part is applied at the top, representing the load from upper stories of a building....
This research study aims to evaluate the cyclic response of wide-flange beam - to - rectangular HSS column connections through experimental tests. Six steel moment connections are tested with three different configurations of the diaphragms: through diaphragm connections, external diaphragm connections, ...
COLUMNBEAMTEE STUBEXPERIMENTALTen full-scale specimens consisting of wide-flange beams shear connected by means of tee stubs to hollow structural section (HSS) column faces were tested. Shear–displacement and shear–rotation behaviour were documented and five possible failure modes were identified for ...
The experimental results showed a considerable effect of the end plate thickness on the structural behaviour of the connection and the connected beam. Moreover, the fire tests have revealed different connection failure modes, such as excessive end plate deformations, column buckling, and bolts ...
