Mechanical Model for Drift-Induced Punching of Slab-Column Connections without Transverse Reinforcement

Aurelio Muttoni, Katrin Beyer, Ioannis Sokratis Drakatos

A mechanical model is presented for predicting the momentrotation relationship of interior slab-column connections without transverse reinforcement when subjected to seismically induced drifts. The model accounts explicitly for the three load-transfer acti ...

Internal slab-column connections under monotonic and cyclic imposed rotations

Aurelio Muttoni, Katrin Beyer, Ioannis Sokratis Drakatos

Reinforced concrete flat slabs supported by slender columns are often used as gravity load resisting system for buildings in regions of moderate seismicity. Current codes of practice determine the displacement capacity of slab-column connections using empi ...

Seismic behaviour of slab-column connections without transverse reinforcement

Ioannis Sokratis Drakatos

Reinforced concrete (RC) flat slabs supported by slender columns are often used as gravity load resisting system for buildings in regions of moderate and high seismicity. Such buildings are typically braced by RC walls, which carry the largest portion of t ...

Experimental investigation on seismic behaviour of slab-column connections

Aurelio Muttoni, Katrin Beyer, Ioannis Sokratis Drakatos

Code design of slab-column connections to resist seismically induced drifts is currently based on empirical relationships for both moment and deformation capacity. The results of tests on slabcolumn connections are however sensitive to the conception of th ...

Mechanical Model for flexural behaviour of slab-column connections under seismically induced deformations

Aurelio Muttoni, Katrin Beyer, Ioannis Sokratis Drakatos

Reinforced concrete (RC) flat slabs supported on columns are one of the most widely used structural systems for office and industrial buildings. In regions of medium to high seismic risk RC walls are typically added as lateral force resisting system and to ...
