Slab-column subassemblages, modelled after a reinforced concrete flat plate building, are tested under combined gravity and lateral loads. The tests include different levels of gravity loads and compare biaxial lateral loading with uniaxial loading. To study the behavior of a repaired connection, one test is repeated after the slab-column specimen is repaired with epoxy and grout. The post-failure behavior of slab-column connections is investigated and the adequacy of bottom slab reinforcement detailing to prevent progressive collapse is assessed. Existing strength and lateral stiffness models are compared with the experimental results. Data from past research are collected to investigate the ductility and drift capacity of slab-column connections. Studies are conducted on the seismic response of reinforced concrete buildings with flat slab construction. Nonlinear dynamic analyses are performed on five typical building systems. A simple seismic design recommendation is proposed for slab-column connections that limits the level of gravity shear to ensure minimal drift capacity.
