Abstract:
Construction of this 150 ft (46 m) diameter dome featured minimum investment in formwork and equipment for precasting and erection. The dome was made of 150 site-precast units, connected by cast-in-place slots of concrete. The slabs, cast on top of each other, used a minimum of formwork and no special curing or handling equipment was required. Steel falsework supported the dome during erection. The dome ring was then prestressed, lifting the dome off the falsework.
