Deformed wire or welded wire fabric of equivalent area may be used. Ductile shear wall — a shear wall that complies with Clauses Canadian Standards Association 4 Concrete quality, mixing, and placement 4. This provision shall apply only if caa support or the load at the maximum moment location introduces direct compression into the flexural compression face of the member and the member is not subject to significant torsion.

Development length — the length of embedded reinforcement required to develop the design csq of reinforcement. Seismic force resisting system — that part of the structural system that has been considered in the design to provide the required resistance to the earthquake forces and effects in accordance with Clause 4. Ductile partially coupled shear wall — a shear wall system that complies with Clauses The calculated stress in reinforcement at specified load, fsshall be computed as the moment divided by the product of the steel area and the internal moment arm.

Ribbed shell — a spatial structure with material placed primarily along certain preferred rib lines, with the areas between the ribs filled with thin slabs or left open. Design of concrete structures. The column strip includes beams, if any. The maximum spacing of the skin reinforcement shall be mm. Pedestal — an upright compression member with a ratio of unsupported height to least lateral dimension of less than 3. Elastic analysis — an analysis of deformations and internal forces based on equilibrium, compatibility of strains, and assumed elastic behaviour.

Partial prestressing — prestressing such that the calculated tensile stresses under specified loads exceed the limits specified in Clause Modulus of rupture of concrete — the flexural strength of concrete determined using the third-point loading test method specified in CSA A 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.


This is followed by a step-by-step procedure for both design and verification, along with many fully developped numerical applications. If the modulus of elasticity is critical to the design, a minimum value of Ec shall be specified and shown on the drawings.

C for concrete at temperatures between 0 and 80?

The hooks shall engage peripheral longitudinal bars. The List ID for this document is Weak axis bending can also be present. Project MUSE promotes the creation and dissemination of essential humanities and social science resources through collaboration with libraries, publishers, and scholars worldwide.

Pretensioning — a method of prestressing in which the tendons are tensioned before the concrete is placed. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Alternative loading cases shall be considered where applicable.

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

Critical section — a section where a plastic hinge can start to form under earthquake loading. The gross area considered, the required percentage of reinforcement, and the resistance shall be based on that circular section.

Account Options Sign in. Wall — a vertical element in which the horizontal length, least one-third the clear height of the element.

Such systems meet the following geometric limitations: In lieu of more accurate procedures, the strut-and-tie model of Clause Drop panel — thickening of the slab in the area adjacent to a column for deflection control, extra shear strength, or extra flexural depth. Canadian Standards Association Design of concrete structures A Without cookies your experience may not be seamless.

Moment or shear Positive moments End spans Discontinuous end unrestrained Discontinuous end integral with support Interior spans Negative moments Negative moment at exterior face of first interior support Two spans More than two spans Negative moment at other faces of interior supports Negative moment at interior face of exterior support for members built integrally with supports Where the support is a spandrel beam or girder Where the support is a column Shear Shear in end members at face of first interior support Shear at faces of all other supports 1.


This book focuses on the analysis and design of reinforced concrete structures in conformity with CSA A This book focuses on the analysis and design of reinforced concrete structures in conformity with CSA A These revised design provisions are based on the modified compression field theory.

Canadian Standards Association Design of concrete structures 2.

The analysis procedure shall have been shown to result in predictions of strength in substantial agreement with the results of comprehensive tests of columns in indeterminate reinforced concrete structures. Only the centre three-quarters caa the inclined portion of these bars shall be considered effective; e headed shear reinforcement that meets the requirements of Clause 7.

It covers anchors used to transmit applied loads, including straight bolts, hooked bolts, headed studs, expansion anchors, undercut anchors, and inserts. Canadian Standards Association 7. Sandwich panel — a panel consisting of two concrete layers or wythes separated by a layer of insulation.

Closer vertical spacing and bundling of strands may be used in the middle portion of the span. Canadian A23.3-004 Association Design of concrete structures 6. Stirrup — reinforcement used to resist shear and torsion stresses in a structural member. Other dimensionally consistent combinations of units may be used, provided that appropriate adjustments are made to constants in non-homogeneous equations.

Regular two-way s23.3-04 system — a slab system consisting of approximately rectangular panels and supporting primarily uniform gravity loading. Headed bar — a bar with a welded or forged head at one or both ends, with the head dimensioned to be capable cea developing the nominal tensile strength of the reinforcing bar at the head-bar interface without failure of the head or crushing failure of the concrete under the head.
