Development of overhead line masts The overhead lines with their masts are the cores of the electrical power supply. The masts are mainly made of wood, concrete or steel and can have a variety of designs. For the high-voltage and extra-high-voltage grid (220kV and 380kV), steel lattice masts are usually used to allow for large heights and spans. The individual bars of these lattice-like masts are mainly made of hot-rolled angle steels, which can be
Dr.-Ing. Christian Keindorf was appointed professor for offshore constructions at Kiel University of Applied Sciences in 2015. At the Institute of Shipbuilding and Maritime Technology he is responsible for development and research in this field...
The Chamber of Engineers of Lower Saxony represented by the President of the Chamber of Engineers of Lower Saxony, Dipl.-Ing. Kammeyer, publicly appointed and sworn in Prof. Dr.-Ing. Christian Keindorf as an expert for supporting structures of onshore and offshore wind turbines on September 1, 2015.
In honor of Professor Peter Schaumann and to mark the completion of his 60th birthday, the staff of the Institute for Steel Construction at Leibniz University of Hanover have written a commemorative publication. In addition to the current staff of the institute and the former PhD students of Professor Schaumann, many colleagues and companions have followed the request and contributed to the Festschrift.
Load-bearing behaviour and fatigue strength of sandwich towers for wind turbines New publication of the dissertation by Prof. Dr.-Ing. Christian Keindorf on the subject of "Load-bearing behaviour and fatigue strength of sandwich towers for wind turbines" The output and size of wind turbines has continued to increase in recent years. This inevitably increases the demands on the tower constructions, which were previously designed as tubular steel, prestressed concrete or lattice towers.
