The prototyping and experimental verification of the modular connector (MC) Beta prototype model, including an examination of the connector's cyclic performance, was described. The Beta prototype was provided by iterating between structural and thermodynamical/fluid flow finite element analysis through the electronic exchange of three-dimensional solid geometry CAD files. The MC Beta prototype is evaluated at full-scale in full beam-to-column connections under the AISC prototype and referenced to a joint in a prototype structure. The experimental results of the scaled MC Beta prototype after casting detailed that transmits beam flange compressive forces directly to the column during cyclic response. The results also show that the MC Beta achieves a high monotonic ductility and suffer no distress in a certain inch of diameter ASTM A325 bolts.
