Tocumen International Airport | South Terminal Building
Panama City, Republic of Panama
Critical reliability analysis and constructability peer review of this new terminal building roof design that features use of large tubular steel roof beams and columns supporting transverse steel I-beams not aligned with the columns. This roof framing arrangement caused the structural designers to analyze the roof behavior using a structural framing system known as "moment frames" in a way never done before to resist earthquakes. In customary moment frames, the columns and beams are in the same plane. Since this offset beam arrangement and the use of large tubular steel beams and columns in seismic force-resisting moment frames was a world's "first", and the new terminal is an Essential Structure.
