To advanced modelling of end plate joints

The behaviour of end plate can be described using various analytical models.

The most common analytical approach is component method. However

this method can be used only for the joints with specific geometry and specific

loading. This method gives reliable results for common endplate joints.

On the other hand numerical methods, especially finite element method, can be

used for the design of the joints with any geometry and any loading. Many works

have been published on the modelling of joints using finite element method.

This research have been focused on creating the most accurate numerical models

using solid elements. Such models are not applicable for practical design. The aim

of author’s research is to create rules and recommendations for design of joints

using simple elements like shell and beam elements only so that this model can be

applied for practical design. Absence of guidelines for creation of numerical

model using shell and beam elements and for assessment of the joint components

limits using of the numerical methods. The aim of Author’s research is creation

of guidelines for modelling and assessment of end plate of bolted joints.

This paper presents results of experimental and numerical investigation of T-stub,

which usually simulate behaviour of the end plate. Two different specimens were

prepared and experimentally investigated. Numerical models were created on

the base of experimental results.
