We were very excited to see the bridges and stairs being fabricated at Larson Steel in Gilroy. These will be extremely important features of our home so they need to be designed, engineered, fabricated and installed carefully.
HSS 5×5 with 1/2 inch Wall
Although we had some initial ideas regarding the bridge design, Hector Guerra of Larson Steel designed the structural steel components. He recommended that we use two pieces of tube steel, 5 inches wide by 5 inches deep, with 1/2 walls. Knowing we didn’t want any ‘bounce’ or movement in the bridges, he thought this basic structural design would work.
This is the main bridge that goes from the foyer across the atrium to the living room. It will be covered with Madrone hardwood flooring from the Santa Cruz Mountains. We want this to be solid. Rock solid.
This bridge goes from the Living Room to the Master Suite. The bridge decking will be made of glass, fritted for safety and frosted for privacy. Importantly, using glass will allow light from the clerestory windows to go into the lower level, which will reduce the electricity required over the building’s life.
Due to the narrow 38-1/2 inch opening between the steel column and the feature concrete wall, the stairs were a challenge to design. We used HSS 2×8 with 3/16 wall for one stringer and, by the concrete wall, 3/8 inch plate.
It was very rewarding to see the design coming together.
