| Abstract | In order to study the seismic behaviors of fabricated steel frames with bolted beam-height adjustable steel beam-to-column connections (BHA connections), a six-story steel frame was designed to run pseudo-dynamic experiments. Experiments were first carried out with the steel frames with and without BRBs under three different types of seismic records under 35gal and 70gal. Then the seismic records of EL_CENTRO amplified from 220gal to 1600gal were loaded on the braced frame. Results showed that there was no detachment, sliding, or yielding detected in BHA connections. After BRBs were installed, the story drift and the top-story maximum displacement could easily meet the codes, and the structure was still working in the elastic stage under 620gal. It could therefore be concluded that BHA connections have excellent seismic performance and they are suitable for application in fabricated steel frames. The braced frame using BHA connections has good lateral stiffness and energy dissipation capacity. |
