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.

Some examples of non-homogeneous equations are found in Clauses Collector — an element that serves to transfer forces within a structural diaphragm to members of the seismic force resisting system. It is based on either elastic or inelastic behaviour.
Spiral column — a column in which the longitudinal reinforcement is enclosed by a spiral. Deformed wire or welded wire fabric of equivalent area may be used.
In calculating dc and A, the effective clear concrete cover need not be taken to be greater than 50 mm. Comment on draft standards Influence national and international standards development by commenting on draft standards online. a23.3-0

Such tests shall simulate the effects of differential settlement, creep, shrinkage, and temperature change based on a realistic assessment of such effects occurring in service. Accordingly, this simplified method shall not be used for members subjected to significant tension, and the longitudinal reinforcement for all members shall be proportioned as specified in Clause These revised design provisions are based on the modified compression field theory.

Canadian Standards Association Design of concrete structures A 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. A closed tie can be made up of several reinforcing elements with seismic hooks at each end. Canadian Standards Association Design of concrete structures Strong connection — a connection that remains elastic while adjoining members experience yielding a233-04 a result of the design displacement.
For other cxa, the values shall be modified as Note: The calculation of k shall be based on the properties specified in Clause Beam — an element subjected primarily to loads and forces producing flexure.
This structural system qualifies for a force modification factor, Rdof 4. If the effects of cracking are not included, the redistribution of stresses due to the anticipated cracking and the effects of this a23.3-044 on the reinforcement layout should be explicitly considered in the design of the reinforcement.

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.

In determining the geometry of the truss, account shall be taken of the required dimensions of the struts and ties. The hooks shall engage peripheral longitudinal bars.

If the modulus of elasticity is critical to the design, the designer should establish whether such concrete can be produced. Stirrup — reinforcement used to resist shear and torsion stresses in a structural member.
