Erich Cziesielski

Erich Cziesielski (born April 26, 1938 in Bucharest , Romania ) is an emeritus professor for building physics and civil engineering at the Technical University of Berlin .

Career

After graduating from high school in Berlin (1954), he studied civil engineering at the TU Berlin (graduation in 1963). He then worked as a scientific assistant and, on a part-time basis, created static calculations for a large number of high-rise buildings in large panel construction in Saarland and Berlin. In parallel to this practical activity, he carried out fundamental experiments and wrote theoretical treatises on the construction method, which was still new at the time, e.g. B. on the load-bearing capacity of panes that are combined from individual walls of large panel construction to form a large pane. The publication about it was translated into Japanese and supplemented together with Fritz Leonhardt . Cziesielski also developed a ventilated joint system for walls in concrete sandwich construction, which reduces the problems of joints sealed with sealing compounds . He received a utility model for this system, and the joint system was sold in large areas of Europe and the Middle East (see Figure 1).

After working as an assistant in Berlin, he was employed at the Federal Research Institute for Forestry and Wood Management in Hamburg as a research assistant. The focus of the work there was the investigation of damage to wooden speedboats of the Bundeswehr and then, based on this, the development of a new, load-bearing hull that made it possible for the ships to travel across waves and at higher speed even in rough seas. During this time, he also did his doctorate on the buckling behavior of orthotropic plates . The results formed the basis for formulations in DIN 1052 (timber construction).

In 1970 Cziesielski became the managing director of an international building materials group as head of the research and development department.

In 1974 Cziesielski received a call to the Technical University of Berlin for the chair for general civil engineering (building physics and civil engineering). During his teaching, he developed the concept that building physics is one of the mathematical and scientific foundations for methodical construction, whereas previously construction was largely characterized by traditional craftsmanship and the “ trial and error ” method .

In 1983 Cziesielski founded the CRP Ingenieurgemeinschaft Cziesielski, Ruhnau + Partner GmbH (CRP Bauingenieure GmbH) in Berlin, which has branches in Hanover, Hamburg and Munich. Cziesielski became a test engineer for structural engineering in Berlin (specializing in solid and timber construction) and was appointed as a publicly sworn expert. The office was and is involved in a large number of important building projects, both in an advisory capacity in terms of building physics and in the framework of structural planning (e.g. Chamber Music Hall Berlin, Berlin State Library , Pergamon Museum , Berlin, Lindenoper Berlin).

Until his retirement in 2003, Cziesielski carried out extensive research in various areas. The research was practice-oriented; the results were largely incorporated into standards or formed the basis for guidelines. Cziesielski was a member and chairman of a large number of committees of the German Standards Committee and the German Institute for Building Technology. In addition, from 1993 to 1997 he was chairman of the building physics group in the International Association for Bridge and Building Construction .

Research priorities

Building physics investigations: e.g. B. Sealing of structures made of waterproof concrete, z. B. by an elevated, ventilated floor (see Fig. 2). The construction was carried out on several buildings, including the chamber music hall of the Philharmonie Berlin . Calculation and rehabilitation of thermal bridges (see Figures 3a and 3b); Weather protection of external walls, stopping of corrosion through thermal insulation in the area of concrete external walls (several 10,000 m² of walls were renovated using this method) and the like. a.

Constructive development of components: z. B. Adhesion behavior of ceramic coverings on thermal insulation composite systems and wooden substrates, improvement of inverted roofs in terms of thermal insulation , reduction of wind forces with ventilated outer walls together with Gerhardt.

Investigation methods in construction: z. B. Locating corroded reinforcement in concrete components according to the electrical potential difference method using a trolley for the extensive examination of components (see Figure 4), generating a largely natural, artificial driving rain for component testing. The test facility is nationally and internationally certified.

Stability and load-bearing capacity of wooden structures: e.g. B. Wooden cylinder shells, the formation of roof panes from chipboard or from boards, dents in panels and. a.

(1) Joint sealing on concrete walls using joint profiles embedded in concrete - Eurofit system
(2) Raised rear-ventilated floor. The ventilation removes any water that may have penetrated.
(3a) Mold infestation in the area of a thermal bridge
(3b) Refurbished thermal bridge through electrical heating
(4) Investigation of corroded reinforcement using the potential difference method on bridges
