ABSTRACT

Who has never experienced any inconvenience at home when fixing a piece of furniture, or a frame, because of a fixing system not perfectly adapted to the situation? Although in these two examples the risk of an element falling is relatively low, this is not always the case. Indeed, although often considered as an unimportant detail, the fastening systems are nevertheless very often important safety elements (fixing of railings, structural elements ...) and are subjected to heavy loads.

The purpose of this article is to present the main elements to know in order to be able to select, size and install the fasteners in reinforced concrete.

Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

 INTRODUCTION

Fasteners are usually invisible when you enter a building or civil engineering structure. Yet they're everywhere. From the fixing of railings to the largest structural equipment, it is often necessary to resort to anchoring solutions. As unfamiliarity with the operating principles of anchors can present high risks, both economically and in terms of personal safety, it's vital to master them as well as possible.

There are many different building materials, such as concrete, steel and wood. As each has its own advantages and disadvantages, it's rare for a building to be made of just one material. This is why, to guarantee the integrity of structures, it is essential to ensure that the connections between these different materials are sufficiently resistant.

The aim of this article is to present the main criteria and methods for sizing anchors for fastening steel elements to a reinforced concrete structure. Concrete-to-concrete, steel-to-steel fastenings or fastenings to other support materials (e.g. masonry) will not be dealt with in depth.

First, we look at the theoretical principles of dowelling, before studying dowel sizing.
