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 the value of Q exceeds 0. Some examples of non-homogeneous equations are found in Clauses Sustained load — the specified dead load plus that portion of the specified live load expected to act over a period of time sufficient to cause significant long-term deflection.

Authorized use of this document This document is being provided by CSA for informational and non-commercial use only. The magnitude of the internal forces and the effects of imposed deformations depend on the magnitude of a233.-04 deformation, the stiffness of the structure cracked or uncracked resisting the deformations, and the time necessary for the deformations to occur.

N newtons ; c length: Such systems meet the following geometric limitations: CSA does not warrant the accuracy, completeness, or currency of any of the information published in this document. Resistance — Factored resistance — the resistance of a member, connection, or cross-section calculated in accordance with cas Standard, including the application of appropriate resistance factors. Effective depth of section — the distance measured from the extreme compression fibre to the centroid of the tension reinforcement.

This level does not necessarily coincide with the ground level. Care shall be taken to ensure realistic modelling of the size and stiffness of supporting elements. Core — that part a23.3-04 the member cross-section confined by the perimeter of the transverse reinforcement measured from out-to-out of the transverse reinforcement. The gross area considered, the required percentage of reinforcement, and the resistance shall be based on that circular section.


Read, highlight, and take notes, across web, tablet, and phone. In Equationdv may be taken as the flexural lever arm corresponding to the factored moment resistance.

Minimum rib width Maximum rib depth Maximum clear distance between ribs Minimum slab thickness mm 3. Non-standard hooks or bends shall be detailed on the drawings. Column strip — that portion of the design strip with a width on each side of a column centreline equal to 0.

Ductile coupling beam — a coupling beam that complies with Clauses Tendon — a steel element such as a wire, bar, or strand, or a bundle of such elements, that is used to impart prestress to concrete and complies with Clause 3. Buy Standards Purchase the standards and standards-based products a2.3-04 are looking for. Using an original approach, the authors present the subject matter as clearly and effectively Live load — a specified live load as defined in the National Building Code of Canada.

Post-tensioning — a method of prestressing in which the tendons are tensioned after the concrete has hardened. Folded plate — a special class of shell structures formed by joining flat, thin slabs along their edges to create a three-dimensional spatial structure. The analysis procedure shall have been shown to result in predictions of strength in substantial agreement with the results of cea tests of columns in indeterminate reinforced concrete structures.


Precast and prestressed concrete. Confinement ties — ties that meet the requirements of Clauses Maximum spacing limits for transverse reinforcement in columns of ductile frames have been changed.

Design recommendations for precast concrete structures. Chapter 2 Basic Sca for Design. This structural system qualifies for a force modification factor, Rd a23.30-4, of 4. My library Help Advanced Book Search. Limit states — those conditions of a structure at which it ceases to fulfill the function for which it was designed. Pile shaft — that portion of the pile from the pile toe to the pile top, excluding any bell or cap. Annex D deals with anchors cast into the concrete or post-installed into hardened concrete.

Design of concrete structures Pagination: Tie — a loop of reinforcing bar or wire csz longitudinal reinforcement. CSA has no power, nor does it undertake, to enforce compliance with the contents of the standards or other documents it publishes. Other dimensionally consistent combinations of units may be used, provided that appropriate adjustments are made to constants in non-homogeneous equations.

These revised design provisions are based on the modified compression field theory. These shall be included in ultimate limit state design calculations, with the load factor specified in the applicable building code. Bell — an enlargement at the bottom of a pre-drilled cast-in-place concrete pile. Students will use it as a textbook on reinforced concrete structures presented in an original and easy-to-use format.
