Australian Engineered Fasteners and Anchor Council (AEFAC) and the Concrete Institute of Australia (CIA) is pleased to present the seminar:  - Concrete fastenings technique - past, present and future .

Professor Rolf Eligehausen, considered by many as the "Godfather in the theory" of fastners and anchors, explores this reality and the pit falls of concrete anchoring via -
 
Standards Australia TS 101:2015 which is superseded by AS 5216:2018 is the Australian deemed-to-satisfy design guidelines for fastenings to concrete. In the seminar, new developments which are currently not covered by SA TS 101 and AS 5216 will be discussed, in particular:
 
  • Connections with post-installed reinforcement: Influencing factors, qualification, design
  • Harmonization of design rules for  connections with post-installed reinforcing bars and fastenings with bonded anchors
  • Fastenings with supplementary reinforcement under tension, shear, combined tension and shear loads, tests and proposed model
The design of connection points between steelwork elements and concrete elements often falls between the two designers involved. To choose the most efficient connection method and provide a safe design, engineers need to know the methods of anchorage that are commonly available and understand the failure modes involved with this methods.

The choice of fixing, quality of concrete fixed to and method of installation as well as incorrect design all contribute to failures. The importance of on-site testing of designs and installations should not be underestimated.

Rolf Eligehausen
Rolf Eligehausen was Professor and Head of the Department of Fastening Technology at the Institute of Construction Materials, University of Stuttgart, Germany until 2009.

Rolf has more than 30 years of experience in research and testing of anchor technology. Since 1986 he has chaired the fib Task Group “Fastenings to Concrete and Masonry” and since 2002 the CEN Working Group responsible for drafting EN1992-4 “Design of Fastenings in Concrete”. He is a member of ACI Committees 355 “Anchorage to Concrete”; 349 “Concrete Nuclear Structures”; and 408 “Bond and Development of Reinforcement”. 

Since 1996 he has been a Partner in the Engineering Office, Eligehausen & Asmus, which specializes in fastening technique. He has authored or co-authored more than 250 papers on reinforced concrete and fastening technique and is co-author of the textbook “Anchorage in Concrete Construction”.
