Alternate design proves economy of precast, prestressed design for pier shed
Pier shed planned for cast in place, post-tensioned concrete, was redesigned using precast, prestressed elements; barrel roof elements were cast 3 in. thick, 7 1/2 ft wide, and 162 ft long, with 7 wires 3/8 in. in diam pretensioned to 13 kips each; to cover 40 ft bay, 5 units were assembled with 5 in. space for cast in place concrete between them; valley beam spans 146 ft to give support to edges of barrel roof; no-slump concrete was used for precast elements with Plastiment as plasticizer and initial set retarder.
