Publishing information
This British Standard is published by BSI Standards Limited, under licence from The British Standards Institution, and came into effect on 31 May 2012. It was prepared by Technical Committee ISE/104, Concrete reinforcing and prestressing
steels. A list of organizations represented on this committee can be obtained on request to its secretary.
Supersession
This British Standard supersedes BS 5896:1980, which is withdrawn.
Relationship with other publications
This standard has been revised to follow BS EN 10138-1 (in preparation).
Definitions, symbols, steelmaking and manufacturing processes, routine inspection and testing, test methods, identification of the manufacturer and technical class and verification of mechanical properties in the case of dispute may be taken from BS EN 10138-1, when published.

Engelhardt, Michael D.; Popov, Egor P. - Behavior of Long Links in Eccentrically Braced Frames
Author: Engelhardt, Michael D.; Popov, Egor P. | Size: 59.6 MB | Format:PDF | Quality:Scanner | Publisher: UNIVERSITY OF CALIFORNIA AT BERKELEY | Year: 1989 | pages: 414
This report describes an experimental investigation and associated studies on the behavior of long, flexural yielding links in seismic-resistant Eaentrically Braced Frames (EBFs). EBFs provide ductile behavior under severe earthquake loads by restricting yielding to beam segments called "links". Short, shear yielding links are preferred because of their demonstrated excellent plastic rotation and energy dissipation capacities. Longer, flexural yielding links, however, can offer important architectural advantages and have been used on a number of recently constructed EBFs. Little experimental data has been available on the behavior of long links under cyclic loading.
The central focus of this report is an experimental investigation on fourteen 213 scale subassemblages subject to cyclic loads. The subassemblages model a portion of a single-diagonal EBF with the rinks attached to the columns. 'The testing program showed that the dominant failure mode for long links attached to columns is fracture of the link flange at the link-to-column connection. Rased on this experimental program, the recommendation is made that long links attached to columns not be used in EBFs. The test results suggest, however, that long links located between two braces can provide acceptable perfamance, although short Iinks are still preferred for best overall performance.
Because of the very high axial force and bending moment typically carried by the beam segment outside of the link, this member can buckle before link inelastic rotation is fullydeveloped, with a consequent loss in the overall system perfomance. Problems with the beam can be avoided by adhering to capacity design principles. A preliminary design procedure based on capacity design concepts is developed for the beams and braces of an EBF.
Based on the findings of this investigation, combined with the results of previous EBF research, preliminary design recommendations are provided for the use of long links not attaclled to columns. Included are recommendations on the design yield strength, ultimate strength, plastic rotation capacity and stiffening requirements for long links. The testing program has also demonstrated the suitability of selected brace-to-link connection details for use in EBFs with long or short links.

The present work mat be considered as an introductory text in nonlinear functional analysis and its applications, even though not many of the results proved in the book depend on the full apparatus of infinite-dimensional normed linear spaces.

The Atlas of Stress-Strain Curves, Second Edition is substantially bigger—in page dimensions, number of pages, and total number of curves—and better than the previous edition. It contains over 1400 curves, almost three times as many as in the 1987 edition. The curves are normalized in appearance to aid making comparisons among materials. All diagrams include metric (SI) units, and many also include U.S. customary units. All curves are captioned in a consistent format with valuable information including (as available) standard designation, the primary source of the curve, mechanical properties (including hardening exponent and strength coefficient), condition of sample, strain rate, test temperature, and alloy composition. Curve types include monotonic and cyclic stress-strain, isochronous stress-strain, and tangent modulus. Curves are logically arranged and indexed for fast retrieval of information. The book also includes an introduction that provides background information on methods of stress-stain determination, on data presentation and analysis, and on application of the results.
