This unique project involved the seismic strengthening of an existing log cabin with a stone masonry enclosed porch. The strengthening consists of the addition of a new steel moment resisting frame with concrete spread footings at the open end of the main room. Strengthening also included the addition of new steel lag screws in order to connect the existing logs together to act as shear-resisting elements. The stone masonry piers are connected to the roof diaphragm, which is also strengthened to resist the design seismic forces.
