Long-term deflections shall be determined in accordance with Clause 9. Cement Association of Canada.

The values specified in this Table shall be used directly for members with normal-density concrete where follows: In such cases, the joint in the girder should be offset a distance at least equal to the depth of the beam.

Such members are often encountered in engineering practice, particularly in buildings. Sandwich panel — a panel consisting of two concrete a2.33-04 or wythes separated by a layer of insulation.

If Vf exceeds 0. Boundary elements — portions of a wall, typically at the ends, that are reinforced by vertical reinforcement and can contain transverse reinforcement. Ties or spirals, if used, shall be placed not more than mm from the point of the bend. N newtons ; c length: Canadian Standards Association Bond Development and Splice Reinforcement pp.

Plastic hinge — a region of a member where inelastic flexural curvatures occur. Plain reinforcement — reinforcement that does not conform to the definition of deformed reinforcement. The clauses of CSA A Resistance — Factored resistance — the resistance of a member, connection, or cross-section calculated in accordance with this Standard, including the application of appropriate resistance factors.

Annexes are designated normative cwa or informative non-mandatory to define their application. Lifting stresses — stresses in a tilt-up panel during lifting. High-strength concretes vary in their brittleness and need for confinement.

Probable moment resistance — the moment resistance of a section calculated using axial loads Ps and Ppwhere applicable; 1.

This book is intended for practicing engineers as well as for engineering students. Design cross-section — the representative panel cross-section at the maximum moment and deflection locations of the panel for which the design forces and deflections are determined and from which the resistance and stiffness are calculated.

Development length for a bar with a standard hook a23.3-40 tension — the length measured from the critical section to the outside end of the hook the straight embedment length between the critical section and the start of the hook [point of tangency] plus the radius of the bend and one bar diameter. The top surface of the column concrete placed a2.33-04 the floor shall extend at least mm into the floor from the face of the column.

If you do not agree with any of the terms and conditions contained in this Legal Notice, you may not load or use this document or make any copies of the contents hereof, and if you do make such cs, you are required to destroy them immediately. Design according to CSA A Flat plate — a flat slab without drop panels. Concrete q23.3-04 Plain concrete — concrete that contains no reinforcing or prestressing steel or less reinforcing or prestressing steel than the specified minimum for reinforced concrete.

Limit states — those conditions of a structure at which it ceases to fulfill the function for which it was designed.

Pile cap — a reinforced concrete element connected to the top of a pile or pile group that transfers loads from the superstructure to the pile or pile group. See Note 3 of fsa preliminary Notes to Annex C.

Longitudinal torsion reinforcement shall be anchored as specified in Clause The calculation of k shall be based on the properties specified in Clause Design of concrete structures. Shear wall — a wall or an assembly of interconnected walls considered to be part of the lateral-load-resisting system of a building or structure.

Collector — an element that serves to transfer forces within a structural diaphragm to members of the seismic force resisting system. PUQ- A23.3-40 concrete construction – pages.

The crack spacing parameter, szshall be taken as dv or as the maximum distance between layers of distributed longitudinal reinforcement, whichever is less. Base of a structure — the level at which earthquake motions are assumed to be imparted to a structure. Other dimensionally consistent combinations of units may be used, provided that appropriate adjustments are made to constants in non-homogeneous equations. Wall — a vertical element in which the horizontal length, least one-third the clear height of the element.

The maximum spacing of the skin reinforcement shall be mm. Spiral — a helical tie complying with Clauses 7.

Deflections may be calculated using formulas for elastic deflections based on effective moments of inertia as specified in Clauses 9. The hooks engage peripheral longitudinal bars.

Annex D deals with anchors cast into the concrete or post-installed into hardened concrete. Contents Chapter 1 Materials. Column capital — an enlargement of the column adjacent to the underside of a slab to improve the shear strength of the slab.

Deformed reinforcement — deformed reinforcing bars, deformed wire, welded smooth wire fabric, and welded deformed wire fabric complying with Clause 3.
