Space for the auditorium for the high school in Culver City, California, was limited to two acres. The architects, Flewing and Moody of Los Angeles, chose a fan-shaped shell which permitted seating of 1,250 persons, was free of obstructions, and with the back row of seats only 50 feet from the stage. The folded dome segments of the roof are designed to put compression on the concrete, making it self-supporting and eliminating both supporting walls and central columns. Relief of the roof load is accomplished by a thrust arm which carries stress to the ground and forms the handle of the fan-shaped shell. A peripheral frame of reinforced concrete at ground level ties the entire structure. This form is additionally strengthened by a diametric tie beam extending at grade along a line paralleling the base of the fan design. Each rib of the roof is joined at the dome in a reinforced concrete cap. Non-bearing panels of glass link the free-standing roof with the stage structures, which is designed in a 60 foot arc. Entrances are provided through the glass walls into lobbies at either side of the stage. The folded dome was designed as a series of segmental arched elements which converge at the crown junction with the supporting buttress. The design analysis assumed both two-hinged and three-hinged conditions, with hinges at the bases and either a hinge or full continuity at the crown. The buttress arm was shaped and proportioned to balance the dead load of the dome segments. The dome was designed for a full live load of 12 pounds per square foot.
