Two EU projects for Steel & Composite Structures professor Milan Veljkovic

TU Delft’s Professor Milan Veljkovic (Structural Engineering department) is participating in two European Commission approved projects titled EqualJoints and Inno3DJoints. Both projects will be funded by the EU’s Steel & Coal Fund.

Inno3Djoints - ‘Click system’ for reuse and modular construction

The aim of the Inno3DJoints research project is to develop a so-called ‘plug-and-play’ joint to connect steel hollow profiles and lightweight steel beams. Hollow profiles and beams are often welded together but this is time consuming and does not allow for the construction to be taken apart and mounted again somewhere else. Veljkovic wants to introduce a click system for steel constructions so  mounting and disassembling time can be reduced considerably. That would not only profit the building industry but would also promote a circular economy concept in the construction sector. The new system can also be used to extend or renovate existing buildings.

Current building regulations lack explicit rules for the use of such innovative systems. That is why Veljkovic and the project partners will create special software to predict the behaviour of the 3D plug-and-play joints. Their calculations cover normal load bearing resistance as well as loading occasioned by seismic activity (earthquakes) or fires. The resulting data will be used to create a set of guidelines to simplify the design procedure for architects.

The project is a joint effort between 7 partners, including the universities of Coimbra (Portugal) and Naples (Italy) and a number of Portuguese and Spanish steel companies, among which Condesa and Famental.

Equaljoints_Plus – behaviour of steel joints during earthquakes

The Equaljoints project focuses specifically on disseminating the knowledge and results from an earlier Coal & Steel Research Fund supported project of the same name. This project was primarily aimed at developing competencies and criteria for steel joints used in buildings in earthquake prone areas. The new project is about valorisation and spreading the acquired knowledge so engineers, architects, building companies and steel producers can use it to their advantage. The research data and the (design) guidelines will be translated into 12 languages, including Dutch, and will be made available via a designated website. There will also be a mobile phone app to predict the behaviour of steel joints during an earthquake, and various seminars and workshops.

For this particular project 100% costs have been granted.

There is a clear overlapping of projects’ objectives therefore a PhD student is already  employed at TU Delft. In addition to permanent staff a  postdoc will be employed in autumn to complete the team.
