Structural system strategy
My structural system strategy was to place the columns ( I used W-Wide Flange-Column W12 x 26) at the main wall joints and along floor openings. Beams (W shape W14 x 30) were placed on the gridline connecting each column. Beam systems (W shape W8 x 10) were designed to support the load from the floor and roof along the south - north direction. Beam systems should avoid any floor openings.
