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.

It is based on either elastic or inelastic behaviour. Canadian Standards Association Sa 0. This provision shall apply only if the 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.
Longitudinal torsion reinforcement shall be anchored as specified in Clause Although CSA administers the process and establishes rules to promote fairness in achieving csz, it does not independently test, evaluate, or a23.3-0 the content of standards.
Bond Development and Splice Reinforcement pp. Annexes are designated normative mandatory or informative non-mandatory to define their application. Specified load — a load specified by the National Building Code of Canada without load factors.

This book is intended for practicing engineers as well as for engineering students. Jacking force — a temporary force exerted by the device that introduces tension into prestressing tendons.
Care shall be taken to ensure realistic modelling of the size and stiffness of supporting elements. For non-prestressed composite members containing more than one type of concrete, the portion of the member in compression shall determine whether the values specified in Table 9.
Construction joints in floors should generally be located near the midspan of slabs, beams, or girders unless a beam intersects a girder in that location. Canadian Standards Association R. Canadian Standards Association 8. Slab band — a continuous extension of a drop panel between supports or between a support and another slab band. The required splice lengths shall be shown on the drawings.
In Equationdv may be taken as the flexural lever arm corresponding to the factored moment resistance. New requirements for slab band construction are also specified. Whenever the square root of the concrete strength is determined, the concrete strength and the square root of the concrete strength are both expressed in megapascals.

For other shapes, the radius of gyration may be computed using the gross concrete section. These revised design provisions are based on the modified compression field theory. Without cookies your experience may not be seamless.
N newtons ; c length: 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. Anchorage of the reinforcement shall be explicitly considered.
Otherwise, sze shall be computed ca Equation Chapter 7 Bond Development and Splice Reinforcement. Ductile shear wall — a shear wall that complies with Clauses Design displacement — the total lateral displacement expected for the design basis earthquake calculated in accordance with Clause 4. It includes requirements for compression flanges for assemblies of interconnected walls. Built on the Johns Hopkins University Campus.
Typical values of Ep range from to MPa. Partial prestressing — prestressing such that the calculated tensile stresses under specified loads exceed the csx specified in Clause Account Options Sign in.

Selected pages Title Page. Construction loading may govern the determination of Ma.
Read, highlight, and take notes, across web, tablet, and phone. Otherwise, torsional effects may be neglected. Use of this document constitutes your acceptance of the a233-04 and conditions of this Legal Notice. Chapter 2 Basic Concepts for Design. Provisions for determining member stiffnesses have been added. Middle strip — that portion of the design s23.3-04 bounded by two column strips.

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. The column concrete shall be well integrated with the floor concrete. The applicable load combination shall be taken as the one that results in the most unfavourable effect for the limit state under consideration. Canadian Standards Association Pile — an elongated structural element drilled or driven into the ground for supporting loads by end bearing, friction, or both.
Tie — a loop of reinforcing bar or wire enclosing longitudinal reinforcement. Higher strengths can require prequalification of concrete suppliers and contractors and special construction techniques. When the simplified method specified in this Clause is used, all other clauses of Clause 11 shall apply, except Clause For a spandrel beam where the torsion is caused by a slab, the factored torsion in the spandrel can be assumed to vary linearly from zero at midspan to 0.
This structural system qualifies for a force modification factor, Rdof 3.
Ductile connection — a connection that experiences yielding as a result of the design displacement. Precast concrete — concrete elements cast in a location other than csz final position in service. The user of this document is authorized to do only the following:
