There is a trend in architecture and structural engineering towards more and more lightweight structures, as such structures are not only elegant but also minimizing the use of material. They are sustainable in the true sense. An inherent feature of lightweight structures is their tendency to be lively. Numerous exciting and breath taking structures such as membrane roofs, cable net structures and cable-supported footbridges have been built and they all require additional engineering efforts, regarding dynamics. Early lightweight footbridges have caused comfort problems for the users. Today engineers have learnt their lessons from several disasters and have included “dynamics” in the curriculum of engineering students. At our chair at the Technical University Berlin (TU Berlin) it has become an important research aspect. Beyond passive tuned mass dampers, investigation on semi-active vibration control will enable us to go beyond present limits towards more lightweight and elegant, more sustainable structures.

Arndt Goldack

Lecture: Dynamic Lightweight Structures
@ 19.30, IAAC Auditorium
Open to the Public

Dr.-Ing. Arndt Goldack  was born in 1969 in Stuttgart, Germany. In 1996 he graduated in civil and structural engineering at the University of Stuttgart, and in 2004 Awarded Doctorate (Dr.-Ing.), Thesis “Structural behavior and Bracing of High Rise Tubes for Solar Updraft Towers”.

From 1996 to 2003 he was a Research assistant at the Institute for Structural Design with Prof. Jörg Schlaich and Prof. Werner Sobek, University of Stuttgart.

In 2003 he then commenced as Structural Engineer with schlaich bergermann und partner, Berlin, Stuttgart, until 2011. During this time he contributed to projects in China, Germany, India, Spain, USA:

- Stress ribbon bridge “Slinky springs to fame”, Oberhausen

- Membrane roof for Estadio Madrid La Peineta

- Gänsebachtal Bridge: Integral Bridge for High Speed Trains, length 1001m

- Cable Stayed Bridge crossing Yamuna River in New Delhi, India: span 250m

- Independent Review of the Second Vivekananda Bridge in Kolkata, extradosed bridge

- Lufthansa A380 Service Hall in Frankfurt

- Dynamic design of almost all footbridges by sbp

- Research Project: Design of Lightweight Footbridges for Human Induced Vibrations, Goldack et. al., JRC-ECCS 2009 in cooperation with University of Porto, TU Delft and RWTH Aachen.

Since July 2011 he has been a Researcher at the Chair of Conceptual and Structural Design, TU Berlin, studying the dynamics of bridges, pedestrian induced vibration, experimental modal analysis, lightweight structures, lightweight concrete, structural control.
