Studie zur aktuellen Situation des Nachhaltigkeitsverständnisses in Bauunternehmen
Authors: Hofmann Sascha , Wicke Dorina , C̆adez̆ Ivan 
Published: October 2015

AbstractDas Nachhaltigkeitsverständnis der deutschen Bau‐ und Immobilienwirtschaft konzentriert sich insbesondere auf das Gebäude und dessen Lebenszyklus. Als Entscheidungskriterium für die Auftragsvergabe von Bauleistungen sowie in den Geschäftsprozessen von Bauunternehmen ist Nachhaltigkeit bisher nicht von Bedeutung. Für die gesamtgesellschaftliche Nachhaltigkeitsentwicklung ist jedoch das Nachhaltigkeitsverständnis auch auf die Unternehmensebene auszuweiten. Unternehmerische Nachhaltigkeit beinhaltet die gleichrangige Berücksichtigung ökologischer, ökonomischer und soziokultureller Aspekte in den Geschäftsprozessen.Wesentliche Ergebnisse der Studie sind, dass Nachhaltigkeit als Bestandteil der Unternehmensphilosophie und des strategischen Managements in Bauunternehmen gesehen, jedoch unterschiedlich umgesetzt wird. Bei der Umsetzung stehen soziokulturelle und ökologische Maßnahmen im Vordergrund; die ökonomische Bedeutung von Nachhaltigkeit als Wettbewerbsfaktor ist dagegen weniger ausgeprägt. Unternehmerischen und idealistischen Motiven für die Umsetzung der Nachhaltigkeit in Bauunternehmen stehen insbesondere hohe Kosten und ein hoher Personalaufwand sowie fehlende Kenntnisse über die Umsetzung und den Nutzen als wesentliche Hemmnisse gegenüber. Zur Steigerung des unternehmerischen Nachhaltigkeitsbewusstseins sollten daher sowohl die Verbesserung von Transparenz und Wissensvermittlung als auch die Entwicklung von geeigneten Instrumenten und Handlungsanweisungen angestrebt werden.Survey of sustainability in construction companiesSustainability in German construction mainly focuses on the building and its lifecycle. For a holistic sustainability approach corporate sustainability has to be considered in addition. This means implementation of environmental, social and economic aspects in business processes. Currently sustainability mainly remains unconsidered in construction companies in general as well as a decision criterion in construction tendering in specific.The study reveals that corporate sustainability is gaining more and more importance in German construction industry but is operated in different ways. However, operational implementation mainly focuses on environmental and social aspects. Economic aspects as a competitive advantage remain unattended. Idealistic and corporate drivers for implementing sustainability in construction companies are opposed to barriers as limited capital and personal capacities as well as missing understanding. In order to improve a holistic sustainability approach increasing transparency, further understanding of corporate sustainability and appropriate measures for implementing and assessing corporate sustainability are of prime importance.
Konzentrierte Innovation: Die Regenbrücke Stefling als Stabbogenbrücke aus Beton
Authors: Stetter Hans , Hentschinski Stefan , Fritsche Thomas 
Published: October 2015

AbstractDie Regenbrücke Stefling ist als Beton‐Stabbogenbrücke ein neuer, moderner Brückentyp. Besonders hervorzuheben ist neben guten gestalterischen Elementen die Kombination verschiedener optimierter Bauweisen und Konstruktionsdetails, die zu einem Querschnitt führen, der eine äußerst geringe Bauhöhe aufweist. Hauptmerkmale sind hier der Werkstoff Beton anstelle von Stahl für den Stabbogen, der Einsatz verbundloser Vorspannung und die Ausbildung der Hänger als Netzwerk. Zusätzlich ist dieser Brückentyp in wirtschaftlicher Hinsicht äußerst konkurrenzfähig. Dies wurde an der Regenbrücke Stefling bestätigt.Innovation concentrated – Regenbrücke Stefling: a tied arch bridge in concreteThe Regenbrücke Stefling is a new and modern bridge structure of tied arch bridges in concrete. Particularly there is to be emphasised beside good formative elements the combination of different optimised construction methods and construction details which induce a cross section which shows an extremely low construction height. Main characteristics are the material concrete in place of steel for the tied arch, the application of internal unbonded prestressing and the construction of the hangers as a network. In addition, this type of bridge is extremely competitive in economic regard. This was confirmed by the Regenbrücke Stefling.
Gradientenbeton – Numerische Entwurfsmethoden und experimentelle Untersuchung gewichtsoptimierter Bauteile
Authors: Herrmann Michael , Sobek Werner 
Published: October 2015

AbstractDie Gradierung von Betonbauteilen durch eine kontinuierliche Veränderung von Materialeigenschaften wie Porosität, Festigkeit oder Steifigkeit in bis zu drei Raumrichtungen ermöglicht eine Anpassung des Bauteilinneren an das vorherrschende statische oder bauphysikalische Anforderungsprofil. Diese Anpassung kann zur Massenminimierung und zur Erzielung multifunktionaler Eigenschaften eingesetzt werden. Numerische Entwurfsmethoden liefern das Gradientenlayout, welches als digitaler Bauplan für diese Bauteile dient.Im vorliegenden Artikel werden Versuche an gradierten Balken im Originalmaßstab beschrieben. Sie erlauben eine Aussage über das Tragverhalten sowie das Masseneinsparpotenzial gradierter Betonbauteile im Vergleich zu Bauteilen aus Normalbeton. Anschließend werden die Versuchsergebnisse mithilfe numerischer Simulationen nachvollzogen. Die so kalibrierten Modelle bilden die Ausgangsbasis für die Entwicklung numerischer Entwurfsmethoden, die auf einem Topologieoptimierungsansatz basieren.Functionally Graded Concrete – Numerical Design Methods and experimental studies on mass minimized componentsFunctional gradation of precast elements makes it possible to align the internal composition of structural components with the specified structural and thermal performance requirements by continuously altering the characteristics of the material, including its porosity, strength or rigidity, in up to three spatial dimensions. This principle can be applied to minimise the mass of the element and to create multi‐functional properties. Numerical design methods are used to develop the gradation layout that serves as a digital blueprint for such components.This paper describes true‐to‐scale tests performed on functionally graded beams. These tests make it possible to derive conclusions with respect to the elements' structural behaviour as well as weight savings that can potentially be achieved compared to structural components made from normal concrete. Test results are subsequently replicated by numerical simulations. The models calibrated in this step establish the basis to develop numerical design methods that rely on the principle of topology optimization.
Mechanism‐Based Trapping of the Quinonoid Intermediate by Using the K276R Mutant of PLP‐Dependent 3‐Aminobenzoate Synthase PctV in the Biosynthesis of Pactamycin
Authors: Hirayama Akane , Miyanaga Akimasa , Kudo Fumitaka , Eguchi Tadashi 
Published: October 2015

AbstractMutational analysis of the pyridoxal 5′‐phosphate (PLP)‐dependent enzyme PctV was carried out to elucidate the multi‐step reaction mechanism for the formation of 3‐aminobenzoate (3‐ABA) from 3‐dehydroshikimate (3‐DSA). Introduction of mutation K276R led to the accumulation of a quinonoid intermediate with an absorption maximum at 580 nm after the reaction of pyridoxamine 5′‐phosphate (PMP) with 3‐DSA. The chemical structure of this intermediate was supported by X‐ray crystallographic analysis of the complex formed between the K276R mutant and the quinonoid intermediate. These results clearly show that a quinonoid intermediate is involved in the formation of 3‐ABA. They also indicate that Lys276 (in the active site of PctV) plays multiple roles, including acid/base catalysis during the dehydration reaction of the quinonoid intermediate.
Efficient Electrochemical Conversion of CO2 to HCOOH Using Pd‐polyaniline/CNT Nanohybrids Prepared in Situ
Authors: Zhao Chenchen , Yin Zhongshu , Wang Jianlong 
Published: October 2015

AbstractPalladium has been proved to be an effective catalyst for CO2 electrocatalytic reduction. In this paper, nanostructured Pd particles fixed on polyaniline‐covered MWNTs surfaces (Pd‐PANI/CNT) were synthesized using an in situ method by reducing H2PdCl4 in a mixture of MWNTs and aniline with sodium citrate as protective stabilizer. TEM micrographs indicate that the addition of sodium citrate optimizes the size and distribution of the nanoparticles. In a 3‐electrode system, both catalysts exhibit efficient and sustainable CO2 conversion towards formate but the one with sodium citrate addition is even better. The highest faradaic efficiency happens at −0.8 V vs. SCE and can be as high as 83 %. Based on the experiments, we put forward a mechanism of Pd‐catalyzed CO2 electroreduction in aqueous solution in which Pd forms a PdHx hybrid that is involved in the reduction process with Pd.

AbstractThe reaction of the N‐thiophosphorylated thiourea (HOCH2)(Me)2CNHC(S)NHP(S)(OiPr)2(HL), deprotonated by the thiophosphorylamide group, with NiCl2leads to green needles of the pseudotetrahedral complex [Ni(L‐1,5‐S,S′)2]⋅0.5 (n‐C6H14) or pale green blocks of thetranssquare‐planar complextrans‐[Ni(L‐1,5‐S,S′)2]. The former complex is stabilized by homopolar dihydrogen CH⋅⋅⋅HC interactions formed byn‐hexane solvent molecules with the [Ni(L‐1,5‐S,S′)2] unit. Furthermore, the dispersion‐dominated CH⋅⋅⋅ HC interactions are, together with other noncovalent interactions (CH⋅⋅⋅N, CH⋅⋅⋅Ni, CH⋅⋅⋅S), responsible for pseudotetrahedral coordination around the NiIIcenter in [Ni(L‐1,5‐S,S′)2]⋅0.5 (n‐C6H14).
