Abstract
A method of seismically strengthening a structure having a concrete beam mechanically coupled to a concrete deck. The method comprises forming a continuous, substantially linear bore through the deck and the beam and then attaching the deck to the beam via a threaded fastener. The deck and the beam are compressed between an enlarged head and a nut of the threaded fastener. Additionally, the method comprises placing a fireproof cap on an end of the threaded fastener protruding from the nut.
