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.

Ductile moment-resisting frame — a moment-resisting frame that complies with Clauses Deformed wire or welded wire fabric of equivalent area may be used. Moment-resisting frame — a frame in which columns, beams, and joints resist forces through flexure, shear, and compression.

For other shapes, the radius of gyration may be computed using the gross concrete section. Sandwich panel — a panel consisting of two concrete layers or wythes separated by a layer of insulation. 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.

Ductile partially coupled shear wall — a shear wall system that complies with Clauses Transfer — the act of transferring force in prestressing tendons from jacks or the pretensioning anchorage to the concrete member.

In calculating dc and A, the effective clear concrete cover need not be taken to be greater than 50 mm. The values specified in this Table shall be used directly for members with normal-density concrete where follows: Modulus of rupture of concrete — the flexural strength of concrete determined using the third-point loading test method specified in CSA A C for concrete at temperatures between 0 and 80?

Canadian Standards Association c cda making an angle of 45? 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. Students will use it as a textbook on reinforced concrete structures presented in an original and easy-to-use format. The beneficial effects of confinement can be accounted for if substantiated by test results.

Ribbed shell — a spatial structure with material placed primarily along certain preferred rib lines, with the areas between the ribs filled with thin slabs a23.3-04 left open. Boundary elements do not necessarily require an increase in wall thickness. Project MUSE Mission Project MUSE promotes the creation and dissemination of essential humanities and social science resources through collaboration with libraries, publishers, and scholars worldwide.

Embedment length — the length of embedded reinforcement provided beyond a critical section.

Core — that part of the member cross-section confined by the perimeter of the transverse reinforcement measured from out-to-out of the dsa reinforcement. Tendon — a steel element such as a wire, bar, or strand, a2.33-04 a bundle of such elements, that is used to impart prestress to concrete and complies with Clause 3.

Nominal resistance — the resistance of a member, connection, or cross-section calculated in accordance with this Standard, without including resistance factors. Limit states — those conditions of a structure at which it ceases to fulfill the function for which it was designed.

Contents Chapter 1 Materials. These revised design provisions are based on the modified compression field theory. Buckling prevention ties — ties that meet the requirements of Clause Thin shell — a three-dimensional spatial structure made up of one or more curved slabs or folded plates whose thicknesses are small compared to their other dimensions.

Purchase Buy This Book in Print. A23.3-004 strength — the specified minimum yield strength or yield point of reinforcement.

Except for connections that are part of a primary seismic force resisting system, this requirement may be waived if the connection is restrained on four sides by beams or slabs of approximately equal depth. Base of a structure — the level at which earthquake motions are assumed to be imparted to a structure. The analysis procedure shall have been shown to result in predictions of strength in substantial agreement with the results of comprehensive tests of columns in indeterminate reinforced concrete structures.

Design recommendations for precast concrete structures. Design width — the width of a tilt-up panel to be reinforced to withstand the factored loads tributary to it. The maximum spacing of the skin reinforcement shall be mm.
