Study Of The Performance Of ASTM A615 Rod As An Anchor Bolt In The Construction Of Structures

Abstract

This study analyzed the mechanical behavior of ASTM A615 steel reinforcing bars used as anchor bolts in steel structures, taking into account structural design requirements, the available materials, and the stresses acting on this type of element. It emphasized the need to harmonize international standards, such as NEC SE EC and AISC 360-16, with the actual conditions of the Ecuadorian market, particularly with the products supplied by the local steel industry. Through an experimental approach, the structural response of anchor bolts manufactured from ASTM A615 steel was evaluated, analyzing their behavior under tensile forces and their compatibility with the criteria established in different design standards, such as NEC SE EC, AISC 360-16, and ASTM F1554. The results showed that this steel exhibits high tensile and shear strength, exceeding the characteristic values of steels commonly used for anchor bolts, such as ASTM A36 and ASTM F1554 Grade 55 and Grade 105. Therefore, ASTM A615 steel is considered suitable for use as an anchor bolt in structural situations dominated by controlled and static loads; however, its use is not recommended in contexts that require high ductility or energy dissipation, since it has limited deformation capacity. Although it has favorable strength properties, current standards do not explicitly support its application; therefore, a thorough technical analysis and the use of conservative design criteria are required.
