The Martin

Seattle, Washington

The Martin, an upscale 24-story multi-family residential tower with subterranean parking, is located in the dynamic Belltown neighborhood of downtown Seattle. The structural system is cast-in-place concrete, with post-tensioned slabs and a shear wall core for seismic and wind resistance.

For the first time anywhere in the world, the Martin incorporated a revolutionary seismic design approach, with steel fibrous reinforced concrete (SFRC) used as a rebar replacement in shear wall link beams.

The SFRC eliminated all link beam diagonal bars -- the bars that create major buildability challlenges in conventionally reinforced link beams -- and significantly reduced the quantities of remaining rebar. The result was a simple and buildable system that easted congestion, facilitated faster construction, and reduced rebar tonnage.
