She was elected as the President of the Board of Directors at Turkish Structural Steelwork Association between 2001 and 2016 and represented Turkey in the Board of Directors at the European Convention for Constructional Steelwork (ECCS) between 2001 and 2018. She was also elected President of ECCS in 2010 and 2015. Prof. Yardımcı is the first female member of the Board of Directors of ECCS and the first and only female President of ECCS.
She worked together with groups made up of İstanbul Technical University’s professionals for ascertainment of damage, repair and retrofitting studies following various earthquakes in earthquake zones in Turkey and she completed various projects auditing and supervising studies.
Her contribution to development of steel solutions after the heavy earthquakes in in Izmit in 1999 was crowned by a renovated school in steel in Kocaeli supported by national and international stakeholders.
When she was the president of TUCSA, she has initiated works to convince the relevant governmental bodies to publish Regulation for Design, Engineering and Execution of Steel Structures starting from December 2006. She has also initiated establishment of TUCSA Academy to organise courses on constructional steelwork for engineers and architects.
Professor Dr Ing PETER SCHAUMANN concentrated on fire design of steel structures and energy supporting structures such as offshore or windmills in his professional life. He was Chairman of ECCS TC3 Fire Design Of Steel Structures from 2002 to 2014. In 2014, he created a new technical committee: TC16 Energy Support Structures – windmills and offshore, one of his passion topic after Fire!
Prof. Schaumann achieved successfully a large number of research in the fields of Fire Safety Engineering, Structural Engineering and Civil Engineering., particularly focused on fatigue resistance of different kind of welded, bolted and grouted connections and design purposes in wind energy support structures. The most recent projects refer to corrosion effects on fatigue.
He has been the Head of the Institute of Steel Construction at Leibniz Universität Hannover, from which he retired in September 2022.
