Analysis of an 1864 Long-Span Truss Roof
Philadelphia's Wagner Institute has a long-span roof completed in 1864, consisting of wood-and-iron arched trusses supporting wood purlins. The plaster ceiling below the roof is extensively cracked, and gaps in truss joints are present in some locations. The truss structure that supports the roof can be analyzed in several different ways, and this ambiguity makes interpretation of the signs of damage difficult. This paper includes a review of the possible mechanisms that could have been used at the time of construction incorporating the visible materials, including various forms of truss and tied arch. This review provided the key to analysis and interpretation of the damage.
