Seismic Response of Embedded Column Connections: Tests and New Design Methods
Abstract eng: Embedded Column Base (ECB) connections are commonly used in mid- to high-rise moment frame buildings, when exposed base plate connections cannot economically provide adequate strength or stiffness. Results from five full-scale tests on ECB connections are presented to examine their seismic response. The tests indicate that (similar to composite beam column connections), response is controlled by a combination of the following mechanisms: (1) bearing of the column flanges against the concrete, (2) panel zone shear, and (3) vertical restraint to uplift and rotation of the embedded base plate. A new strength model is presented. The model considers these mechanisms, as well as their interactions. Limitations of the research are discussed along with their implications for design.
