There is a partial basement dating back to the 1940’s. This guide presents information on the design of slabs-on-ground, primarily industrial floors. On the corner of Castlereagh and Goulburn streets in the Sydney CBD, Grocon was the developer and builder of Sydney's Masonic Centre. Co Ordinate with the Post Tension Specialist. 3 Design Beam Torsion Reinforcement 7-23 7. Post-tensioning (61) The Post-tensioning (61) component enables Tekla Structures to accurately model most post-tensioning profiles and attributes. Analyses of Frost-Migration under Post-Tensioned Slabs. Overall, the deck was 79. (Co-listed with Civ Eng 5222). The base floor within a building may simply be a cast-in-place concrete slab-on-grade with limited design considerations for structural support or environmental control functions. Nonetheless, as a specialist in the design and construction of post-tensioned concrete building structures for 50 years I feel qualified to submit a review. Monolithic concrete slab is the most cost effective method for constructing cement floors or concrete garage floor. Post-tensioned foundations are designed using the Post-Tensioning Institute (PTI) method first published in 1980 and recently updated with its 3rd edition. The post-tensioning system was the Freyssinet 3, 4 and 5S13 bonded system. Unless otherwise noted, all referenced table, figure, and equation numbers are from these books. The balance load. My background is in structural steel design and construction management. The shallow overall depth of the KF40 ® profile allows post-tensioning tendons to be draped in the spanning and transverse directions of the slab without clashes. Post tension girders support conventionally reinforced joists on a 33’-0” x 33’-0” grid.
