Reinforced Concrete Structures: Design according to CSA A [Omar Chaallal, Mohamed Lecherni] on *FREE* shipping on qualifying offers. visions for the seismic design of high-strength concrete structures in the Canadian standard CSA A– It is noted that the Canadian standard. This paper presents the background experimental and analytical research that was carried out to develop the provisions for the seismic design.

If this document is in electronic form: Connection — a region that joins two or more members, of which one or more is precast. Only the centre three-quarters of the inclined portion of these bars shall be considered effective; e headed shear reinforcement that meets the requirements of Clause 7.

The analysis fsa account for the effects of cracking. Slab ccsa — a continuous extension of a drop panel between supports or between a support and another slab band. Regular two-way slab system — a slab system consisting of approximately rectangular panels and supporting primarily uniform gravity loading. Reinforcement — non-prestressed steel that complies with Clauses 3. Zone to be reinforced with additional ties 45? Some examples of non-homogeneous equations are found in Clauses Bundled bars shall be tied, wired, or otherwise fastened together to ensure that they remain in position.

If the modulus of elasticity is critical to the design, the designer should establish whether such concrete can be produced. Alternative loading cases shall be considered where applicable. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Bell — an enlargement at the bottom of a2.33-04 pre-drilled cast-in-place concrete pile. Critical section — a section where a plastic hinge can start to form under earthquake loading.

Precast concrete — concrete elements cast in a location other than their final position in service. Boundary elements — portions of a wall, typically at the ends, that are reinforced by vertical reinforcement and can contain transverse reinforcement.

Embedment length — the length of embedded reinforcement provided beyond a critical section. CSA is a private q23.3-04 company that publishes voluntary standards and related documents.

Canadian Standards Association Design of concrete structures Basic Concepts for Design pp. For two-way slab construction, n shall be taken as the clear span in the long direction, measured face-to-face of supports in slabs without beams and face-to-face of beams or other supports in other cases. Designer — the person responsible for the design.

For other conditions, the values shall be modified as Note: If deflection is computed, account shall be a3.3-04 of curvatures resulting from differential shrinkage of precast and cast-in-place components and of axial creep effects in a prestressed concrete member. The magnitude of the internal forces 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.

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.

Transfer — the act of transferring force in prestressing tendons from jacks or the pretensioning anchorage to the concrete member. The List ID for this document is Canadian Standards Association Design of concrete structures 6.

For calculating negative moments at interior supports, n shall be taken as the average of the adjacent clear span lengths. Pile cap — a reinforced concrete element connected to the top of a pile or pile group that transfers a23.33-04 from the superstructure to the pile or pile group.

Flexural shear wall — a shear wall that resists in-plane lateral loads by flexural action. Read, highlight, and take notes, across web, tablet, and phone.

Core — that part of the member cross-section confined by the perimeter of the transverse reinforcement measured from out-to-out of the transverse reinforcement. The analysis procedure shall have been shown to result in predictions of strength in substantial agreement with csw results of comprehensive tests of columns in indeterminate reinforced concrete structures. Annexes are designated normative mandatory or informative non-mandatory to define their application.

In Equationdv may be taken as the flexural lever arm corresponding to the factored moment resistance. The crack spacing parameter, szshall be taken as dv or as the maximum distance between layers of distributed longitudinal reinforcement, whichever a223.3-04 less.

Such members are often encountered in engineering practice, particularly in buildings. The value of the coefficient of thermal expansion depends on the type of aggregates, the moisture state of the -6 -6 concrete, and the temperature of the concrete.

In addition, users may not and may. Joist construction shall meet the following limits: It is based on either elastic or inelastic behaviour. Canadian Standards Association Design of concrete structures 2. Built on the Johns Hopkins University Campus. Development length for a bar with a standard hook in tension — the length measured from the critical section to the outside end of the hook the straight fsa length between the critical section and the start of the hook [point of tangency] plus the radius of the bend and one bar diameter.

Factored load effect — the effect of factored load combinations specified in Clause 8. PUQ- Reinforced concrete construction – pages.
