Bioeconomy: What’s new in bioeconomy and what’s not?

Dr. Patrick Dieckhoff from the Fraunhofer-Gesellschaft will be the speaker at the next seminar. The theme of the meeting will be:

Case Study; Bioeconomy: What’s new in bioeconomy and what’s not? Strategic drivers and research policies around the world. Application examples from biomaterials to biological data.

Dr. Patrick DieckhoffDr. Patrick Dieckhoff is Secretary General Science Policy of the Fraunhofer-Gesellschaft. In this role he coordinates the political activities for the President of the Fraunhofer-Gesellschaft, Prof. Dr. Reimund Neugebauer, in Berlin. The chemist and microbiologist with a doctorate is particularly interested in aspects of research and innovation, sustainability and social issues. Since he headed the office of the German Bioeconomy Council, Patrick Dieckhoff has been interested how the potential of natural renewable resources and knowledge about nature can be used and how new sustainable materials, processes and products can be created. As a former journalist, communication, the application of research results and international cooperation are particularly important to Patrick Dieckhoff. There have been close ties between the Technical University of Breslau and the Fraunhofer Society for decades. Patrick Dieckhoff is looking forward to further intensifying these relationships.

The challenges of rehabilitating the Hercílio Luz suspension bridge

This Wednesday (December 16, 2020) Prof. Hermes Carvalho will present the paper

The challenges of rehabilitating the Hercílio Luz suspension bridge

The Hercílio Luz suspension bridge, built-in 1926, has been out of service since 1991 due to high corrosion levels and structural element impairment. A complete rehabilitation project was developed which included the replacement of the impaired items and foundation strengthening. For this, an auxiliary structure was employed to support the central span during the rehabilitation process. A carefully studied load transfer process, where the central span loading is transferred from the eye-bar towards the auxiliary structure will be performed. For this purpose, a synchronized jacking sequence will be used, which was predefined by means of numerical model analysis. All structural elements had their designs evaluated and some geometric changes were implemented.

This lecture will present all the methodology developed in the rehabilitation project of Hercilio Luz bridge, as well as the development stages up to the end of the work.
