ABSTRACT
The objective of this research program was to further evaluate the performance
and constructability of reinforced concrete (RC) column-steel beam-slab systems (RCS)
for use in low- to mid-rise space frame buildings located in regions of high wind loads
and/or moderate seismicity. To better understand these systems, two full scale RCS
cruciform specimens were tested under bidirectional quasi-static reversed cyclic loading.
The experimental portion of this research program included the construction and testing
of two full-scale cruciform specimens with identical overall dimensions but with
different joint detailing. The two joint details evaluated were joint cover plates and face
bearing plates with localized transverse ties. The construction process was recorded in
detail and related to actual field construction practices. The specimens were tested
experimentally in quasi-static reversed cyclic loading in both orthogonal loading
directions while a constant axial force was applied to the column, to simulate the wind
loads in a subassembly of a prototype building. To compliment the experimental work,
nonlinear analyses were performed to evaluate the specimen strength and hysteretic
degradation parameters for RCS systems. In addition, current recommendations in the
literature on the design of RCS joints were used to estimate specimen joint strength and
were compared with the experimental findings.
