This document analyzes the seismic performance of jumbo beams and columns with different types of reduced beam section (RBS) connections through numerical modeling and simulation. It finds that using RBS connections can increase the load capacity of jumbo sections compared to no RBS. Among the RBS connection types modeled (flange cut, web cut, holes in flange, slit in flange), the flange cut with slit connection resulted in the lowest equivalent plastic strain in both the beam and column, indicating it optimizes plastic hinge relocation and reduces premature failure under seismic loading.
