The first part of this article explains the various test guidelines for fasteners and discusses new developments in test guidelines and the associated assessment documents for anchors and headed anchor bolts. Part 2 will present the outcomes of the tests and is scheduled for publication in the next BFT issue.

1 Introduction

A design method for using anchors and headed anchor bolts for load-bearing connections or fastenings in seismic areas was previously only available in technical specification documents, but not in a European standard. A set of rules has long been available for nuclear facilities [21]. However, due to the associated stricter requirements, it is transferable to standard buildings or engineering structures only to a limited extent. Even though Section 7 of EN 1998-1 [8] contains specific rules for composite structures made of steel and concrete, the related provisions do not cover...
