摘要：A precast, prestressed concrete truss which spans between exterior columnsand forms an interior or exterior load bearing wall of a building. The truss includes topand bottom chords interconnected by at least one web member. Prestressed reinforcingmembers in the top and bottom chords apply a compressive stress in the chords. The
top and bottom chords are configured to support concrete planks that form a floorand/or a ceiling of a building in which the truss is used. When used as an interior loadbearing wall, the truss can include at least one opening that forms, for example, acorridor passage large enough for a person to walk through the opening. When used asan exterior load bearing wall, the truss can include at least one window opening.
