Special concentrically braced frames are one of the most common seismic force resisting systems in regions of high seismicity because of their high strength and stiffness. This system relies on tensile yielding and compression buckling of diagonal braces to dissipate energy. In current practice, a gusset plate is used to join the brace to the frame elements. Following a capacity design procedure and using geometrical limits to achieve the required out-of-plane deformation capacity may result in large and uneconomical gusset plates. Moreover, recent experiments have shown that toe weld fractures at the gusset plate, partly due to the opening and closing of the beam-to-column joint, can limit the drift capacity of the system. A more seismically resilient connection has recently been developed based on the concept of a Replaceable Brace Module (RBM). This connection does not require field welding as it can be bolted into place, and it is intended to make the frame easily repairable by confining all damage to the RBM. Previous testing of individual modules has shown that the proposed connection holds promise as an alternative for concentrically braced frames. However, there has not previously been any experimental study of this connection at the system level. This paper discusses the first large-scale testing of a single-storey and single-bay concentrically braced frame with RBM and a shear tab beam-column connection, performed at McMaster University. This experimental study simulates the interaction of all the braced frame components including bracing members, the proposed connection, beam-to-column connection, beam, and column. The experimental program consists of two phases. In the first phase, the frame is subjected to quasi-static cyclic loading up to fracture of one brace. In the second phase, the damaged RBMs are replaced with the new RBMs, and the behaviour of the frame is investigated under the same loading protocol. This paper presents preliminary results from the tests as a step towards making the proposed RBM available for use by design engineers in practice.
