  abstract  = {This study aims at constructing the simulation system of distribution patterns of solar irradiance, sunshine duration and sky factor with the user-friendly interface and sharing this system with users on the Internet. The characteristics of this simulation system are as follows: (1) Web-based user interface, (2) Accessible system through the Internet and (3) Sunlight and skylight simulation based on physically accurate equations with considering various sky conditions and the reflection from the surface of objects. As a case study, impact of the development plans are analyzed and evaluated using this system. Solar irradiance, sunshine duration and sky factor are calculated at the surface of the buildings and open spaces every 10 minutes from 8 to 16 on the winter solstice. The values of these indices are expressed as the ratio to those calculated under the condition with no buildings. In conclusion, this web-based simulation system can be useful for visualizing the sunlight and skylight conditions on outdoor open spaces and the surface of the buildings to evaluate development plans objectively. Users can make access to the system from almost all of the computers connected with the Internet and modify parameters by themselves to get desirable results. Further improvement of the user interface is necessary using more advanced technology of CGI, Java and JavaScript.},

Mit dieser etablierten Methode konnten axiale Traglast und Duktilit{\"a}t von unzureichend bewehrten St{\"u}tzen bereits verbessert werden. Es wurde jedoch festgestellt, dass der umschn{\"u}rte Betonkern dennoch an Festigkeit verliert. Um die Wirksamkeit der Umschn{\"u}rung zu erh{\"o}hen, wird deshalb vorgeschlagen, das umschn{\"u}rende Material vorzuspannen. Dieser Vorschlag wird insbesondere von der neuen Materialgruppe der Formged{\"a}chtnislegierungen inspiriert, die thermisch vorspannbar sind. Bisher sind die Auswirkungen der Vorspannung einer Umschn{\"u}rung auf das Tragverhalten von Betondruckgliedern kaum untersucht worden. Diese L{\"u}cke wird durch systematische Versuche an Betonzylindern mit vorgespannter Umschn{\"u}rung aus Stahl und kohlenstofffaserverst{\"a}rktem Kunststoff geschlossen. Die Abbildung der Versuchsergebnisse durch geeignete Modelle erm{\"o}glicht auch Aussagen zum Verhalten von Betondruckgliedern mit Umschn{\"u}rungen aus anderen Materialien, beispielsweise Formged{\"a}chtnislegierungen. Um diese in den Berechnungen zu simulieren, wird eine f{\"u}r das Bauwesen infrage kommende eisenbasierte Legierung in separaten axialen Versuchen charakterisiert und thermisch vorgespannt. Die in der vorliegenden Arbeit entwickelten neuen Modelle orientieren sich im Wesentlichen an zwei Zielen: dem Abbilden des mehraxialen Spannungs-Dehnungs-Verhaltens des vorgespannt umschn{\"u}rten Betons und dem Berechnen der Restfestigkeit des Betons. Die durchgef{\"u}hrten Versuche und Parameterstudien auf Basis der Modelle zeigen: Die Vorspannung der Umschn{\"u}rung beeinflusst vor allem die Restfestigkeit des Betons wesentlich.

Here the analysis is given as for the usage of some universal computing systems for the solution of such problems. Also if is shown that the quantification of the dynamic models of the complex-composite systems with the variable structure, depending on the character and intensivity of the effects, is necessary. The different variants of the joint and the space structure element modelling are gested. It allows to consider the complex modes of the joint bending-torsional oscillations of such structures as bridges, towers, high-rise buildings. The peculiarities of the modelling and testing of some problems of the objects aerodynamics and the interaction of the frameworks constructions with shock and movable loads are considered. In this paper the examples of the complex-composite structure dynamic analysis are shown. It is achieved by means of some special methods of the input of the real inducements and loads of the exploitated analog-object into the computing model. The suggested models found a wide use both at the design of new structures and the dynamic monitoring of the exploitated structures.},

We investigate the cases when such a combined mesh occurs more preferable for bivariate data interpolation than a pure triangulation. First we describe a modification of the well-known flipping algorithm that constructs a locally optimal combined mesh with a predefined quality criterion. Then we introduce two quality measures for triangular and quadrangular domains and present the results of a computational experiment that compares integral interpolation errors and errors in gradients caused by the piecewise surface models produced by the flipping algorithm with the introduced quality measures. The experiment shows that triangular meshes with the Delaunay quality measure provide better interpolation accuracy only if the interpolated function is strictly convex, as well as a saddle-shaped function is better interpolated by bilinear patches within a combined mesh. For a randomly shaped function combined meshes demonstrate smaller error values and better stability in compare with pure triangulations. At the end we consider other resources for mesh improvement, such as excluding >bad< points from the input set for the mesh generating procedure. Because the function values at these points should not be lost, some linear or bilinear patches are replaced by nonlinear patches that pass through the excluded points.},

  abstract  = {The purpose of this study is to develop self-contained methods for obtaining smooth meshes which are compatible with isogeometric analysis (IGA). The study contains three main parts. We start by developing a better understanding of shapes and splines through the study of an image-related problem. Then we proceed towards obtaining smooth volumetric meshes of the given voxel-based images. Finally, we treat the smoothness issue on the multi-patch domains with C1 coupling. Following are the highlights of each part. First, we present a B-spline convolution method for boundary representation of voxel-based images. We adopt the filtering technique to compute the B-spline coefficients and gradients of the images effectively. We then implement the B-spline convolution for developing a non-rigid images registration method. The proposed method is in some sense of "isoparametric", for which all the computation is done within the B-splines framework. Particularly, updating the images by using B-spline composition promote smooth transformation map between the images. We show the possible medical applications of our method by applying it for registration of brain images. Secondly, we develop a self-contained volumetric parametrization method based on the B-splines boundary representation. We aim to convert a given voxel-based data to a matching C1 representation with hierarchical cubic splines. The concept of the osculating circle is employed to enhance the geometric approximation, where it is done by a single template and linear transformations (scaling, translations, and rotations) without the need for solving an optimization problem. Moreover, we use the Laplacian smoothing and refinement techniques to avoid irregular meshes and to improve mesh quality. We show with several examples that the method is capable of handling complex 2D and 3D configurations. In particular, we parametrize the 3D Stanford bunny which contains irregular shapes and voids. Finally, we propose the B´ezier ordinates approach and splines approach for C1 coupling. In the first approach, the new basis functions are defined in terms of the B´ezier Bernstein polynomials. For the second approach, the new basis is defined as a linear combination of C0 basis functions. The methods are not limited to planar or bilinear mappings. They allow the modeling of solutions to fourth order partial differential equations (PDEs) on complex geometric domains, provided that the given patches are G1 continuous. Both methods have their advantages. In particular, the B´ezier approach offer more degree of freedoms, while the spline approach is more computationally efficient. In addition, we proposed partial degree elevation to overcome the C1-locking issue caused by the over constraining of the solution space. We demonstrate the potential of the resulting C1 basis functions for application in IGA which involve fourth order PDEs such as those appearing in Kirchhoff-Love shell models, Cahn-Hilliard phase field application, and biharmonic problems.},

  abstract  = {In current AEC practice client requirements are typically recorded in a building program, which, depending on the building type, covers various aspects from the overall goals, activities and spatial needs to very detailed material and condition requirements. This documentation is used as the starting point of the design process, but as the design progresses, it is usually left aside and changes are made incrementally based on the previous design solution. These incremental small changes can lead to a solution that may no longer meet the original requirements. In addition, design is by nature an iterative process and the proposed solutions often also cause evolution in the client requirements. However, the requirements documentation is usually not updated accordingly. Finding the latest updates and evolution of the requirements from the documentation is very difficult, if not impossible. This process can lead to an end result, which is significantly different from the documented requirements. Some important requirements may not be satisfied, and even if the design process was based on agreed-upon changes in the scope and requirements, differences in the requirements documents and in the completed building can lead to well-justified doubts about the quality of the design and construction process...},

  abstract  = {Die zunehmend erforderliche Kooperation verschiedener Beteiligter unterschiedlicher Fachbereiche und der Einsatz hochspezialisierter Fachapplikationen in heterogenen Systemumgebungen unterstreichen die Bedeutung und Notwendigkeit neuer Konzepte und M{\"o}glichkeiten zur Schaffung einer computergest{\"u}tzten Integrationsebene. Ziel einer computergest{\"u}tzten Integrationsebene ist die Verbesserung der Kooperation und Kommunikation unter den Beteiligten. Grundlage daf{\"u}r ist die Etablierung eines effizienten und fehlerfreien Daten- und Informationsaustausches zwischen den verschiedenen Fachplanern und -applikationen. Die Basis f{\"u}r die Datenintegrationsebene bildet ein digitales Bauwerksmodell im Sinne eines >virtuellen Bauwerks<, welches alle relevanten Daten und Informationen {\"u}ber ein zu planendes oder real existierendes Bauwerk zur Verf{\"u}gung stellt. Bei der Verwirklichung einer Bauwerksmodell-orientierten Datenintegrationsebene und deren Modellverwaltung erweist sich speziell die Definition des Bauwerksmodells also die Spezifikation der relevanten auszutauschenden Daten als {\"a}ußerst komplex. Der hier vorzustellende Relationen-orientierte Ansatz, d.h. die Realisierung des Daten- und Informationsaustauschs mittels definierter Relationen und Beziehungen zwischen dynamisch modifizierbaren Dom{\"a}nenmodellen, bietet Ans{\"a}tze zur: * Verringerung und Beherrschung der Komplexit{\"a}t des Bauwerksmodells (Teilmodellbildung) * Realisierung eines effizienten Datenaustauschs (Relationenmanagement) Somit stellt der Relationenorientierte Ansatz einen ad{\"a}quaten L{\"o}sungsweg zur Modellierung eines digitalen Bauwerksmodells als Datenintegrationsebene f{\"u}r den Lebenszyklus eines Bauwerkes dar.},
