ACI 562-16 Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary.
ealuatiun—reter to structural ealuation
existing structure—structure for which a legal certificate of occupancy has been issued. For structures thai are not covered by a certificate of occupancy, existing structures are those that are complete and permitted for use or otherwise legally defined as an existing structure or building.
factored load—product of the nominal load and load factor.
faulty construction——defIcient construction resulting from errors or omissions in design or improper construction causing displacement of supporting portions of tlie structure or resulting in deficient materials, geometry, size or location of concrete members, reinforcement or connections.
glass transition temperature—midpoint in transition
over which a polymer resin changes from a glassy state to a
viscoelastic stale as measured pursuant to ASTM D4065. T
— 27°F is the glass transition temperature minus 27°F.
in-place condition—currcnt condition of an existing structure. system. member, connection including component sizes and geometry, material properties. foully construction. deterioration, and damage from an event.
Interface rein forcement—cxisting OF supplemental reinforcement that is properly anchored on both sides of an interface; post-installed reinforcement such as adhesive anchors or mechanical anchors, or other mechanical connections providing a method of force transfer across an interface.
interface shear stress—shear stress resulting from transfer of forces at bonded interfaces between repair material and existing substrate used to achieve composite behavior.
jurisdictional authority—person or entity that has legal control over the applicable building code and permitting procedures for a structure.
licensed design professional——( 1) an engineer or architect who is licensed to practice structural design as defined by the statutory requirements of the pwlssional licensing laws of a state or jurisdiction: (2) the engineer or architect, licensed as described, who is responsible for the structural design of a particular project (also historically engineer of record).
nominal load—magnitude of load specified by the design- basis code before application of any factor.
nonsiructural concrete —any element made of plain or reinforced concrete that is not required to transfer gravity load, lateral load, or both, along a load path of a structural system to the gwund.
owner—corporation, association. partnership. individual. or public body or authority with whom the contractor enters into an agreement and for whom the work is provided. The owner is the party in legal possession of’ the structure.
rehabilitation -repairing or modifying an existing structure to a desired useful condition.ACI 562 pdf download.
