Approach

Newer/recent researches for optimization of hollow profile carrying structures were made with RHS profiles (Rectangular Hollow Section), which are rotated 45° to the (bar) axis. These so called Diamond Bird Break joints (DBB) show significantly increased carrying capacities in the examined parameter-range than conventional joints with RHS profiles.

Comparative calculations, with help of the Finite Elements Method program ANSYS also prove this for joints with triangular hollow profiles (THS). Because the bar-bearing capacity of triangular shaped hollow profiles, compared to rectangle hollow profiles with same cross-sectional areas, are nearly even, preliminary studies show that by the use of triangular shaped hollow profiles, significantly increased joint bearing capacities are possible. For architectural purposes, the selection of triangular profiles is seen as an interesting design opportunity, which can lead to an improvement of the market share of steel construction.

Here the now available research project assesses in an effort to examine and describe the bearing capacity and the failure mechanisms of T-joints with THS-profiles.

In the end, there is the possibility of a calculational proof of a new product with economic and architectural advantages.
