This paper presents the background experimental and analytical research that was carried out to develop the provisions for the seismic design.

Moment-resisting frame — a frame in which columns, beams, and joints resist forces through flexure, shear, dsa compression. Jacking force — a temporary force exerted by the device that introduces tension into prestressing tendons.

Wall — a vertical element in which the horizontal length, least one-third the clear a2.3-04 of the element. Other dimensionally consistent combinations of units may be used, provided that appropriate adjustments are made to constants in non-homogeneous equations.

Notes to tables ca figures are considered part of the table or figure and may be written as requirements. This website uses cookies to ensure you get the best experience on our website. Designers planning to use specified a233.-04 strengths exceeding 50 MPa should determine whether the appropriate concretes are available.

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.


This level does not necessarily coincide with the ground level. Notes to tables and figures are considered part of the table or figure and may csaa written as requirements. New requirements for the design of squat walls have been added in Clause Cover — see Concrete cover.

Each layer of such reinforcement shall have an area at least equal to 0. Canadian Standards Association — All rights reserved. Structural diaphragm — a structural member, such as a floor or roof slab, that transmits forces to or between lateral-force-resisting members. However, Vs shall not be taken as greater than Vf.

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. My library Help Advanced Book Search.

It is possible that Table 9. CSA is a private not-for-profit company that publishes voluntary standards and related documents. 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 a3.3-04 explosions.

For other conditions, the values shall be modified as Note: A closed tie can be made up of several reinforcing elements with seismic hooks at each end.

If the value of Q exceeds 0. Elastic analysis — an analysis of deformations and internal forces based on equilibrium, compatibility of strains, and assumed elastic behaviour. Other dimensionally consistent combinations of units may be used, provided that appropriate adjustments are made to constants in non-homogeneous equations.


Yield strength q23.3-04 the specified minimum yield strength or yield point of reinforcement. Chapter 7 Bond Development and Splice Reinforcement. Footing — a shallow structural element that transfers loads from the superstructure to the bearing strata soil or rock. Modulus of rupture of concrete — the flexural strength of concrete determined using the third-point loading test method cwa in CSA A This process brings together volunteers representing varied viewpoints and interests to achieve consensus and develop a standard.

Precast concrete — concrete elements cast in a location other than their final position in service. The top surface of the column concrete placed in the floor shall extend at least mm into the floor from the face of the column. Design according to CSA A The crack spacing parameter, szshall be taken as dv or as the maximum distance between layers of distributed longitudinal reinforcement, whichever is less. This can be accomplished by post-tensioning or pretensioning.

Buckling prevention ties — ties that meet the requirements of Clause In Equationdv may be taken as the flexural lever arm corresponding to the factored moment resistance. Canadian Standards Association R.
