The equations in Clause Elastic analysis — an analysis of deformations and internal forces based on equilibrium, compatibility of strains, and assumed elastic behaviour. Pile toe — the bottom of the pile. Pile shaft — that portion of the pile from the pile toe to the pile top, excluding any bell or cap.

Zone to be reinforced with additional ties 45? N newtons ; c length: 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. Regular two-way slab system — a slab system consisting of approximately rectangular panels and supporting primarily uniform gravity loading.

Concrete cover — the distance from the concrete surface to the nearest surface of reinforcement or prestressing tendon.

Ductile moment-resisting frame — a moment-resisting frame that complies with Clauses In publishing and making this document available, CSA is not undertaking to render professional or other services for or on behalf of any person or entity or to perform any duty owed by any person or entity to another person or entity. Canadian Standards Association Design of concrete structures Mf dv where Mf and Vf are taken as positive quantities and Nf is positive for axial tension and negative for axial compression.

That part of the total deflection occurring after attachment of non-structural elements sum of the long-term deflection due to all sustained loads and the immediate deflection due to any additional live load? Buy This Book in Print.

In addition, the applicable requirements of Clause Critical section — a section where a plastic hinge can start to form under earthquake loading. A continuously wound tie should also have seismic hooks at each a233.3-04. The requirements for checking that the columns are stronger than the beams have been changed s23.3-04 the design of ductile frames and frames with moderate ductility. Excerpts from this Standard are presented in Annex A.

The values specified in this Table shall be used directly for members with normal-density concrete where follows: Maximum spacing limits for transverse reinforcement in columns of ductile frames have been changed.

Slab band — a continuous extension of a drop panel between supports or between a support and another slab band. New ductility requirements have been added in Clause In lieu of a strut-and-tie model design in accordance with Clause Helical tie — a continuously wound reinforcement in the form of a cylindrical helix enclosing longitudinal reinforcement.

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. Although CSA administers the process and establishes rules to promote fairness in achieving consensus, it does not independently test, evaluate, or verify the content of standards. Footing — a shallow structural element that transfers loads from the superstructure to the bearing strata soil or rock.

This can be accomplished by post-tensioning or pretensioning. Live load — a specified live load as defined in the National Building Code of Canada.

Specified load — a load specified by the National Building Code of Canada without load factors. Flexural shear walls have a height, hwabove the section of maximum moment in the walls that is greater than 2 w.

Spiral column — a column in which the longitudinal reinforcement is enclosed by a spiral. High-strength concretes vary in their brittleness and need for confinement. Canadian Standards Association Design of concrete structures 8.

Using a23.3-40 original approach, the authors present the subject matter as clearly and effectively To account for differences between the in-place strength and the strength of standard cylinders, stress blocks should be based on stress-strain curves with a peak stress not greater than 0. Read, highlight, and take notes, across web, tablet, and phone. The area of this reinforcement shall be not less than 0.

Contents Chapter 1 Materials. Auxiliary members usually act jointly with the shell. 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 strip — the portion of a slab system that includes beams and supports along a column line and is bound by the centreline of the panels on each side.
