A novel hybrid system with RC-encased steel joists
The paper presents the main results of an experimental and numerical study on a novel structural frame system, which employs RC encased steel joist beams and columns. An accurate 3D numerical model has been used to represent the resistance mechanisms in beams and beam-to-column connections. Experimental and numerical outcomes have been employed to develop suitable analytical models to be used in practical design. In particular, the beam flexural response has been investigated, providing a simple relationship for the flexural rigidity at different load levels. Capacity models have been then proposed for the bending and shear resistance of partially and fully-encased beams, and for exterior beam-to-column joints.
