Fire in Parmelee Avenue School, Los Angeles, lasting little over hour, destroyed practically all combustibles in two rooms; two-story structure is of post-tensioned lift-slab type, with slabs of 4000-psi light weight concrete; second-floor slab is 9 1/2 in. thick in room areas and roof slab 10 in. thick at midwidth and 8 1/2 in. at outer walls; prestressing tendons run both transversely and longitudinally; it was determined that, although temperatures approached 2000°, prestressed roof slab was not seriously damaged and structural integrity of building was not affected.
