Fla. Admin. Code Ann. R. 61G15-31.004 - Design of Cast-in-Place Post-Tensioned Concrete Structural Systems
(1) Structural engineering documents shall
show the complete structural configuration and loading requirements of the
post-tensioned system including: member sizes, type of post-tensioning system,
location of all prestressing tendons (in plans and elevation), magnitude of all
prestressing forces, and all design assumptions. Structural engineering
documents shall also show all required non post-tensioned reinforcing steel
including size, spacing, and lengths required for the post-tensioned
system.
(2) If the engineer of
record (EOR) elects to delegate the responsibility for preparation of
calculations and installation drawings to a delegated engineer for the
post-tensioning system, the EOR shall require the submission of installation
drawings for review. Calculations shall also be submitted by the delegated
engineer which show sufficient information to document that the number and size
of tendons provided are adequate to carry all loads shown on the structural
engineering documents. The member dimensions and tendon directions shall match
those on the structural engineering documents, unless otherwise agreed to with
the EOR, via modified structural engineering documents. Installation drawings
shall include the following as a minimum: identification of all the structural
elements designed by the delegated engineer, all details of post-tensioned and
non post-tensioned materials to be used including necessary accessories, and
instructions for construction. If the delegated engineer utilizes or requires
any additional reinforcing to maintain the member sizes shown on the structural
engineering documents, the delegated engineer shall inform the EOR. If any
moments, shears or axial loads are required for the lateral force resisting
system the EOR shall provide them to the delegated engineer for inclusion in
the preparation of the delegated engineering documents. All forces imposed on
the load supporting members from the post-tensioned system shall be reported to
the EOR. The installation drawings and calculations shall bear the seal, date,
and signature of the delegated engineer who prepared them and shall be reviewed
by the EOR for the structure.
(3)
It is the responsibility of the EOR for the structure to review the
post-tensioning system installation drawings together with the shop drawings of
all required reinforcing steel needed for a complete structural
design.
(4) The effect of
post-tensioning on other parts of the structure is the responsibility of the
EOR.
