Cyclic Collector Force with Rotation Tests on AFW were conducted to understand the effect of column rotation on the behavior of All Flange Weld (AFW) collector connection. A test collector with AFW connection, was designed, fabricated, and tested under cyclic collector force in presence of forward and backward column rotation without composite slab and gravity loading. The reaction column was rotated to prescribed rotation with the help of reaction end actuators while keeping the loading actuators free to move. Then the cyclic collector force loading was applied as force-controlled loading through the loading actuators. The test provides effect of column rotation on AFW connection strain demand & evolution, and connection strength. The connection was subjected to destructive loading after completing all the loading in presence of rotations.

Cyclic Collector Force with Rotation Tests on TFW were conducted to understand the effect of column rotation on the behavior of Top Flange Weld (TFW) collector connection. A test collector with top flange weld (TFW) connection, was designed, fabricated, and tested under cyclic collector force in presence of forward and backward column rotation without composite slab and gravity loading. The reaction column was rotated to prescribed rotation with the help of reaction end actuators while keeping the loading actuators free to move. Then the cyclic collector force loading was applied as force-controlled loading through the loading actuators.

Cyclic Collector Force Tests on TFW were conducted to understand the behavior of Top Flange Weld (TFW) collector connection under cyclic collector force (tension and compression) loading. A test collector with top flange weld (TFW) connection, was designed, fabricated, and tested under cyclic collector force without composite slab and gravity loading. The TFW collector connection was subjected to incremental cyclic collector force loading. The loading was performed as a force-controlled loading until the connection yields and switched to deformation-controlled loading after yielding. The cyclic collector force was applied while keeping the reaction column at the fixed position resulting the no rotation on the column. The test provides new knowledge on TFW collector connection properties: strength, stiffness, and deformation capacity.more » « less

Cyclic Collector Force with Rotation Tests on MST were conducted to understand the effect of column rotation on the behavior of Multi-row Bolt Shear Tab (MST) collector connection. A test collector with MST collector connection, was designed, fabricated, and tested under cyclic collector force in presence of forward and backward column rotation with composite slab and in presence of gravity loading. A 2-point gravity loading was applied first to develop the design shear force at the connection. The reaction column was then rotated to prescribed rotation with the help of reaction end actuators while keeping the loading actuators free to move. Then the cyclic collector force loading was applied as force-controlled loading through the loading actuators. The test provides effect of column rotation on MST connection strain demand & evolution, and connection strength.more » « less

Predetermined Collector Force Histories Tests on AFW were conducted to understand the performance of All Flange Weld (AFW) collector connection under different levels of seismic hazards. A test collector with AFW collector connection, was designed, fabricated, and tested under predetermined seismic collector force and inter-story drift histories, without composite slab and gravity loading. The AFW collector connection demands were obtained from nonlinear time-history analyses of archetype steel buildings. Based on these analyses, representative collector force and story drift demands were selected for the test specimen. Snippets of the loading histories corresponding to different seismic hazard levels were extracted, and each loading history was subdivided as necessary based on force and rotation increments. The selected snippet histories of drift and collector force were applied consecutively. For each loading step, the reaction column was first rotated to the target drift using reaction actuators, followed by application of the corresponding collector force through the loading actuators. This procedure was repeated sequentially until completion of the selected snippet. These tests provide insight into the performance of the AFW collector connection under seismic load demands associated with different earthquake hazard levels.more » « less

This research investigated experimentally the seismic performance of steel gravity framing with a concrete slab at the system level. Two half-story, two-by-three bay steel gravity frame specimens were tested under cyclic loading. Bolted-bolted double-angle connections were used for a beam-to-column gravity connection. Primary design variables and construction details include the orientation of the metal deck to the loading direction, the presence or absence of metal deck seams on secondary beams, and the contribution of additional reinforcement bars in the concrete slab. Concrete blocks were positioned at the midpoint of each bay to simulate gravity loads, and a quasi-static displacement-controlled cyclic loading protocol was applied to the specimen using three hydraulic actuators. These investigations confirmed general observations from previous subassembly testing programs that the composite steel gravity framing system can provide substantial flexural stiffness, strength, and ductility under cyclic loading. Further, the test findings showed that the primary design variables and construction details significantly affected the cyclic behavior of composite gravity connections. Comparing the test results from a multi-bay setup and a subassembly testing setup, the cyclic behavior showed remarkable differences, especially for cases with weak axis decking or strong axis decking with a seam. These large differences are attributed to a significant separation of the girder from the column in the subassembly testing setup, which may not be present in a real building. Virtually all previous cyclic loading tests on gravity connections have been conducted in subassembly test setups. These subassembly tests are therefore the basis for the models that are currently used to include gravity frame connections in the seismic performance assessment of buildings, and these models may be quite inaccurate in some cases. The data generated in this system-level testing program is intended to support efforts to develop improved models of gravity connections subject to seismic loading.more » « less
