About this detail

A special seismic force-resisting system beam-to-column connection at grid intersection fourteen. A vertical column per plan supports a horizontal girder per plan with a one-inch thick stiffener plate centered above the column flanges below in four places. A half-inch thick gusset plate connects to the framing members with five-sixteenths inch fillet welds on both sides. A doubler plate is provided on the far side along with a girder connection detailed with complete joint penetration welds and various fillet weld sizes ranging from one-quarter to three-eighths of an inch. Additional stiffening elements and beam members are tied into the node with specific weld symbols and finish-to-bear requirements as designated on the drawing.
