Abstract
In industrial buildings there is often a need to attach processing equipment and other components
to the building’s structure. If the main structure is made of concrete this is usually done by using
anchor plates. An anchor plate is composed of a steel plate, fixed to the concrete with two or more
concrete fasteners. There is a large variety of fasteners with different mechanical means of
operation. Which system to be used depends on the circumstances and may differ quite much.
Based upon the forces and moments which act on the anchor plate one can calculate material
stresses and strains in the anchor plate as well in the fasteners and the surrounding concrete.
These load effects are then compared against the normative... (More)
In industrial buildings there is often a need to attach processing equipment and other components

Based upon the forces and moments which act on the anchor plate one can calculate material
stresses and strains in the anchor plate as well in the fasteners and the surrounding concrete.
These load effects are then compared against the normative failure type capacities in order to
verify the design. Capacities are calculated according to the chosen design code, which in this
project is CEN/TS 1992-4 technical specification by the European Committee for Standardization,
a design code aimed entirely for safety design of anchor plates. The CEN/TS 1992-4 is a
normative document produced by a Technical Committee, and if approved will be adopted into a
Eurocode Standard.

The main problem lies within the fact that there are many different load combinations to be
analysed, including normal operation load cases to severe accident load cases. Each combination
can contain several variable loads and even some loads of dynamic character. This gives a large
number of combinations of normal force, shear forces, bending and torsional moment, all of
which has to be verified. Add to this that it is common for industrial buildings to have thousands
of anchor plates, which is why there is great benefit to automate the safety design process. (Less)
