An analytical development of a working prototype of the modular connector (MC) for seismic-resistant steel moment frames is described in the various stages of development process including interdisciplinary industry meetings at the conceptual stages, extensive analytical research, castability, and constructability studies. MC design for a reliable connection plastic rotation capacity is provided by choosing a limit of useful connection rotation at 0.05 radian. The alpha prototype of MC exhibit the desired behavior as plastic zone causing lower plastic strain in the MC and the stiffness of the base creates significantly lower plastic strain in the bolt threads and no plastic behavior in the bolt shank. Compression pad is provided to transmit the steel beam flange compressive loads directly to the column as the MC cycles between tension and compression loading during seismic response.
