Specification for Structural Joints Using ASTM A325 or A490 Bolts, June 30, 2004 RESEARCH COUNCIL ON STRUCTURAL CONNECTIONS

iii PREFACE The purpose of the Research Council on Structural Connections (RCSC) is: (1) To stimulate and support such investigation as may be deemed necessary and valuable to determine the suitability, strength and behavior of various types ofstructural connections; (2) To promote the knowledge of economical and efficient practices relating to such structural connections; and, (3) To prepare and publish related standards and such other documents as necessary to achieving its purpose. The Council membership consists of qualified structural engineers from academic and research institutions, practicing design engineers, suppliers andmanufacturers of fastener components, fabricators, erectors and code-writing authorities. The first Specification approved by the Council, called the Specification for Assembly of Structural Joints Using High Tensile Steel Bolts, was published in January 1951. Since that time the Council has published fifteen successive editions. Each was developed through the deliberations and approval of the fullCouncil membership and based upon past successful usage, advances in the state of knowledge and changes in engineering design practice. This edition of the Council’s Specification for Structural Joints Using ASTM A325 or A490 Bolts continues the tradition of earlier editions. The major changes are: • • Sections 5.1, 5.2, and 5.3 were editorially revised to clarify strength requirements of slip criticalconnections. Section 6.2.1 was modified to permit the use of A490 type bolts, with round heads equal or larger in diameter than ASTM F1852 heads, without F436 hardened washers. Table 6.1, footnote d, was added to clarify use of non-hardened plate washer to be used in conjunction with an ASTM F436 hardened washer.
