Footing — a shallow structural element that transfers loads from the superstructure to the bearing strata soil aa23.3-04 rock. It is possible that supplementary provisions for structural integrity will be needed for mixed or unusual structural systems or for structures exposed to severe loads such as vehicle impacts or explosions.

The magnitude of the internal z23.3-04 and the effects of imposed deformations depend on the magnitude of the deformation, the stiffness of the structure cracked or uncracked resisting the deformations, and the time necessary for the deformations to occur.

Auxiliary member — a rib or edge beam that serves to strengthen, stiffen, or support the shell. Auxiliary members usually act jointly with the shell. Some examples of non-homogeneous equations are found in Clauses Canadian Standards Association Design of concrete structures 11 Shear and torsion Pile shaft — that portion of the pile from the pile toe to the pile top, excluding any bell or cap. Other dimensionally consistent combinations of units may be used, provided that appropriate adjustments are made to constants in non-homogeneous equations.

Canadian Standards Association 9. Plain reinforcement — reinforcement that does not conform to the definition of deformed reinforcement.

Such models are particularly appropriate in regions where plane sections do not remain plane. Composite concrete flexural members — concrete flexural members of precast or cast-in-place concrete elements, or both, constructed in separate placements but interconnected so that all elements respond to loads as a unit. Jacking force — a temporary force exerted by the device that introduces tension into prestressing tendons. All non-prestressed longitudinal bars of sizes 35M, 45M, and 55M, and all bundled bars, shall be enclosed by ties of at least size 10M.

Pile casing — a steel tube or liner used for pre-drilled cast-in-place concrete pile construction. It is possible that the requirements of this Clause will not be sufficient for structures subject to very aggressive exposure or designed to be watertight.

Canadian Standards Association Design of concrete structures 14 Walls If epoxy-coated reinforcement is used, the value of z given by Equation shall be multiplied by a factor of 1. Canadian Standards Association 8.

The maximum spacing of the skin reinforcement shall be mm. Ductile shear wall — a shear wall that complies with Clauses The prestress force may be assumed to vary linearly from zero at the point at which bonding commences to a maximum at a distance from the end of the tendon equal to the transfer length, assumed to be 50 diameters for strand and diameters for single wire.

Squat shear wall — a shear wall with a height, hwabove the section of maximum moment in the wall that does not exceed 2 w. Sandwich panel — a panel consisting of two concrete layers or wythes separated by a layer of insulation. Designer — the person responsible for the design.

Ties or spirals, if used, shall be placed not more than mm from the point of the bend. Construction joints in floors should generally be located near the midspan of slabs, beams, or girders unless a beam intersects a girder in that location.

Concrete — A32.3-04 concrete — concrete that contains no reinforcing or prestressing steel or less reinforcing or prestressing steel than the specified minimum for reinforced concrete. The hooks engage peripheral longitudinal bars. Prestressed concrete — concrete in which internal stresses have been initially introduced so that the subsequent stresses resulting from dead load and superimposed loads are counteracted to a desired degree.

Thin shells are characterized by their three-dimensional load-carrying behaviour, which is determined by the geometry of their form, the manner in which they are supported, and the nature of the applied load. The List ID for this document is The lateral reinforcement shall be distributed within mm of the top of the column or pedestal and shall consist of at least two 10M bars. Base of a structure — the a233.3-04 at which earthquake motions are assumed to be imparted to a structure.

Each layer of such reinforcement shall have an area at least equal to 0. Annexes are designated normative mandatory or informative non-mandatory to define their application.

Flexural shear walls have a height, hwabove the section of maximum moment in the walls that is greater than 2 w. It is consistent with this definition that a w23.3-04 may be included in the Technical Committee list and yet not be in full agreement with all clauses of this publication.
