Die vorliegende Publikation stammt aus der Reihe "Tipps und Tricks" im Umgang mit Pro Engineer. Es werden BMX-Funktionalitäten zur Dimensionierung eines Massenausgleiches algorithmisch dargestellt. Als Beispiel dient ein Schubkurbelgetriebe, welches bezüglich seiner Gestellkraftkomponenten analysiert wird. Mit Hilfe eines Lancaster-Ausgleiches kann die Lage des Massenschwerpunktes bezüglich der X- und Y-Komponente optimiert werden.

Das Menschmodell MANIKIN bietet dem Anwender neue Möglichkeiten in der Analyse des arbeitstechnischen Umfeldes in der bekannten Pro/ENGINEER Umgebung. Dazu kann auf eine anthropometrische Datenbank zurückgegriffen werden. Neben einfachen Analysen, wie Reichweite und Sichtfenster, steht auch ein umfangreiches Angebot an Ergonomie-Analysen zur Untersuchung von Arbeitsprozessen zur Verfügung. Diese basieren auf den bekannten Grundlagen wie RULA, SNOOK und NIOSH91. Weiterhin ist das Modell gut zur Animation von Menschen bzw. Mensch-Maschine-Interaktionen geeignet, wobei hier ein spezielles Wissen über den Aufbau und den Einsatz von Körpersperrbedingungen zuträglich ist.

In dieser Präsentation wird das universelle FE-Modell eines Kegelrollenlagers vorgestellt. Mittels eines Pro/ENGINEER-Layouts, basierend auf dem Top-Down Designkonzept, kann automatisch innerhalb einer kurzen Bearbeitungszeit ein geprüftes und lauffähiges FE-Modell eines Kegelrollenlagers abgeleitet werden. Dieses Modell kann z.B. in großen Getriebemodellen eingebaut werden, um eine quasistatische Betrachtung mit korrekten Lagersteifigkeiten zu ermöglichen.

Bis 1990 ging die politische, soziale, wirtschaftliche und technische Entwicklung in beiden deutschen Staaten mehr als 40 Jahre getrennte Wege. Das trifft auch für die Ausbildung von Wasserbauingenieuren zu. Die Autoren unternehmen den Versuch, das Bild der zugehörigen Entwicklung im Osten Deutschlands nachzuzeichnen. Sie konzentrieren sich dabei auf die Technische Universität Dresden als den Hauptstandort der damaligen universitären Wasserbauausbildung in der DDR. Im vorliegenden Aufsatz werden die Tatsachen, die Probleme und das Erreichte dargestellt und besprochen. / More than 40 years the political, social, economic and technical development in the two German states went different ways until 1990. This also applies to the education of civil engineers in the field of hydraulic engineering. The author undertakes the attempt to trace a picture of the related development in East Germany. During the GDR-period the Dresden University of Technology was the major place for university education of hydraulic engineers (GDR = German Democratic Republic).

More than 40 years the political, social, economic and technical development in the two German states went different ways until 1990. This also applies to the education of civil engineers in the field of hydraulic engineering. The author undertakes the attempt to trace a picture of the related development in East Germany. During the GDR-period the Dresden University of Technology was the major place for university education of hydraulic engineers (GDR = German Democratic Republic). This is why the development of the education in Dresden and its relations to the hydro practice will be mainly considered here. In this paper the facts, the problems and the achievements are told and discussed. / Bis 1990 ging die politische, soziale, wirtschaftliche und technische Entwicklung in beiden deutschen Staaten mehr als 40 Jahre getrennte Wege.

The construction industry is large and accounts for a major part of the total CO2 emissions each year. The structural engineer has a significant role to decrease the environmental impact of a construction project. This thesis aims to find ways to reach increased environmental sustainability among structural engineers in the construction industry. Barriers to working more environmentally sustainable are investigated to understand what influences the sustainability. To gain data a case study with a qualitative approach was performed at a technical construction consultancy firm in Sweden. Interviews were done mainly with structural engineers but employees working together with the engineers was also interviewed. Through the interviews, insights, thoughts and opinions was gathered which were used to find barriers that could influence the structural engineers. The results show that it is foremost through conscious material selection and optimal structural design that the environmental footprint can be decreased by the structural engineer. Barriers were found to be lack of knowledge, unclear responsibilities, unclear requirements of sustainability in the projects and conflicts between social, financial and environmental sustainability. To improve sustainability endeavours within the company the barriers detected during the study must be dealt with. The results of the study may help direct efforts for implementing sustainability in construction consultancy firms.

Que ce soit dans ses objectifs, son organisation, ses outils ou ses techniques, le projet en architecture subit des transformations profondes. Certaines découlent des politiques publiques, liées notamment à l’environnement, d’autres d’une maîtrise croissante du rapport qualité-coût, d’autres encore des innovations constructives et de l’essor du numérique, d’autres enfin de l’évolution du cadre des marchés publics, à l’exemple de la conception-réalisation. Dans ce contexte, on observe des pratiques de pilotage et de gestion des projets plus complexes dans lesquelles l’architecte n’est plus le seul à détenir la compétence de synthèse. Cette dernière, au contraire, prend des formes plus partagées dans lesquelles l’ingénieur occupe une place croissante. Pourtant, celle-ci reste peu décrite et mal connue, ou limitée dans sa définition à la synthèse d’exécution définie par la loi n° 85-704 du 12 juillet 1985, dite loi MOP (maîtrise d'ouvrage publique). Caractériser les conditions d’exercice de la synthèse et ses impacts sur les processus de projet est l’enjeu de cette thèse. Nous nous intéressons ici à un aspect, certes circonscrit, mais décisif pour la réussite du projet, à savoir les modalités de collaboration entre ingénieurs et architectes : formes de pensées et d’organisation, outils de représentation, divergences et convergences de leurs actions. L’analyse porte sur le partage de la dimension architecturale et constructive dans huit situations de synthèse issues de trois cas d'étude : la Maison Hermès à Tokyo, la station d'assainissement Seine-Aval à Achères, la Fondation Louis Vuitton à Paris.Par une observation sur le terrain et par des entretiens menés auprès d'ingénieurs et d'architectes, ce travail met en avant deux types de résultats : 1) une caractérisation des situations de synthèse qui précise le rôle des représentations, dont trois types sont identifiés : les représentations spécifiques, les représentations échangées et les représentations partagées ; 2) une évaluation des incidences de la synthèse sur le pilotage et le management des projets. Ces résultats mettent en lumière de nouvelles modalités de collaboration entre ingénieurs et architectes et de gestion de projet qui, sans être totalement représentatifs des projets menés en loi MOP, sont susceptibles de les rendre plus efficients. / Whether in its objectives, its organisation, its tools, or its techniques, the architectural project is undergoing profound transformations. Some arise from public policies, notably relating to the environment, others from increasing control over project cost management, yet others from innovations in construction and developments in digital technology, and others, finally, from changes in the framework of public contracts, such as design-build. As a result of these factors, more complex project management practices are emerging, in which the coordinating role is no longer confined to architects alone. Instead, it now takes more collaborative forms, with engineers playing an increasingly more important role. Nonetheless, there has been little description of this synthesising activity and it is poorly understood, or limited in its definition to the execution summary defined by act No. 85-704 of 12 July 1985, the so-called public project ownership (MOP) act. The aim of this thesis is to explain what is meant by project synthesis. We are interested here in a circumscribed aspect of the architectural and construction project – but one decisive to its success – which is the forms of collaboration between engineers and architects: modalities of thinking and organising, representational tools, differences and similarities in their activities. The theoretical and practical implications of this hypothesis will be explored through an analysis of the sharing of the architectural and constructional dimensions of eight examples of synthesis, drawn from three case studies: Maison Hermès in Tokyo, the Seine-Aval sewage plant in Achères, the Louis Vuitton Foundation in Paris. Through observation on the ground and interviews with engineers and architects, this analysis highlights two kinds of result: 1) a description of situations of synthesis, which details the role of representations, identifying three types: specific representations, exchanged representations, and shared representations; 2) assessment of the impacts of synthesis on the conduct and management of projects. These results demonstrate new forms of collaboration between engineers and architects and of project management which, though not entirely representative of projects conducted under the MOP act, offer methodological contributions that could help make them more effective.

The first part of this project focused on evaluating aspects of the environmental management practices of Texas chemical industries, particularly waste generation and management of the data related to these processes. The waste generation data included Texas notifications required to track wastes. The next phase consisted of characterizing industrial waste disposal methods, waste container management, and transportation including an overview of required documentation for each activity. This led to identification of issues encountered from inefficient recordkeeping, ineffective internal communication, or inadequate environmental management systems. The result of an ineffective hazardous waste data management program can be fines, damage to the environment, and even adverse impacts on worker health and safety. For example, for the situations outlined in this document, violations could have resulted in penalties totaling $550,000 per day. This led to an effort to evaluate and develop solutions needed to develop a robust management system. The goal was to provide an operating and hazardous waste management program which optimally resulted in “zero findings” by the state regulatory agency. This would be achieved through personal experiences of this environmental engineer while working at a chemical plant augmented by information obtained through observations of others at the facility and a review of published documentation. This document focuses on the redesign and automation of an ineffective, manual environmental management system by making modifications and enhancements with a focus on effective management of various waste media. The criteria used for determining system optimization includes regulatory compliance and noncompliance penalties, internal communication time, onsite storage accumulation time exceedances, recordkeeping efficiency, number of lost waste containers, and time needed to make waste classifications. Optimization is verified against other alternatives by comparing instances and severity of noncompliance with state and federal regulations. The result was a total environmental management system optimized in a way that ensured compliance and achieved the goal of eliminating violations. It also reduced cost, allowed automated data entry, supported rapid asset location and helped track performance.
