The subject of the Diploma thesis is a design wooden structures of a multipurpose sport building in Šumperk. The floor plan measurements of the building are 45,0 x 48,0 m with the maximum height 15,0 m. The solution is choosen on the basis of two variants. The structures is designed with respect to ultimate and serviceability limit states. The multipurpose sport building is consist of 13 main truss centre to centre spacing 4,0m. The main structural system is design as the three-hinged arched structure made of solid timber and in the second variant as the arched structure made of glue laminated timber. The spatial rigidity of the structure is secured of diagonal bracing. The roofing is carried by rafter which are safed by purlin and then by upper chord. The steel columns are design as a part of gable wall. The project was carried out in the scia Engineer 2014 software. Some of the particular elements both variants were checked and designed by manualy calculating. The thesis includes structural design report, joints structures, drawings and production drawing the element of the three-hinged arched structure.

The diploma thesis is focused on design and assessment of mounted storage hall. I have designed prestressed truss, reinforced truss, beam, column and foundation pad. I have made calculations for consideration of ultimated limit state as well. I have made analysis of internal forces for beams just with manual calculations. Analyses of internal forces for column and foundation pad were found with Scia Engeneer. All calculations are following the Eurocode 2. All designed elements have formwork drawing and reinforcement drawing.

The goal of this thesis is the development of theoretical methods targeting the implementation of topology optimization in structural engineering applications. In civil engineering applications, structures are typically assemblies of many standardized components, such as bars, where the largest gains in efficiency can be made during the preliminary design of the overall structure. The work is aimed mainly at truss-like structures in civil engineering applications, however several of the developments are general enough to encompass continuum structures and other areas of engineering research too. The research aims to address the following challenges:<p>- Discrete variable optimization, generally necessary for truss problems in civil engineering, tends to be computationally very expensive,<p>- the gap between industrial applications in civil engineering and optimization research is quite large, meaning that the developed methods are currently not fully embraced in practice, and<p>- industrial applications demand robust and reliable solutions to the real-world problems faced by the civil engineering profession.<p><p>In order to face these challenges, the research is divided into several research papers, included as chapters in the thesis.<p>Discrete binary variables in structural topology optimization often lead to very large computational cost and sometimes even failure of algorithm convergence. A novel method was developed for improving the performance of topology optimization problems in truss-like structures with discrete design variables, using so-called Kinematic Stability Repair (KSR). Two typical examples of topology optimization problems with binary variables are bracing systems and steel grid shell structures. These important industrial applications of topology optimization are investigated in the thesis. A novel method is developed for topology optimization of grid shells whose global shape has been determined by form-finding. Furthermore a novel technique for façade bracing optimization is developed. In this application a multiobjective approach was used to give the designers freedom to make changes, as the design advanced at various stages of the design process. The application of the two methods to practical<p>engineering problems, inspired a theoretical development which has wide-reaching implications for discrete optimization: the pitfalls of symmetry reduction. A seemingly self-evident method of cardinality reduction makes use of geometric symmetry reduction in structures in order to reduce the problem size. It is shown in the research that this assumption is not valid for discrete variable problems. Despite intuition to the contrary, for symmetric problems, asymmetric solutions may be more optimal than their symmetric counterparts. In reality many uncertainties exist on geometry, loading and material properties in structural systems. This has an effect on the performance (robustness) of the non-ideal, realized structure. To address this, a general robust topology optimization framework for both continuum and truss-like structures, developing a novel analysis technique for truss structures under material uncertainties, is introduced. Next, this framework is extended to discrete variable, multiobjective optimization problems of truss structures, taking uncertainties on the material stiffness and the loading into account. Two papers corresponding to the two chapters were submitted to the journal Computers and Structures and Structural and Multidisciplinary Optimization. Finally, a concluding chapter summarizes the main findings of the research. A number of appendices are included at the end of the manuscript, clarifying several pertinent issues. / Doctorat en Sciences de l'ingénieur / info:eu-repo/semantics/nonPublished

This study proposes novel optimization methodologies for the optimization of problems that reveal non-physical step discontinuities. More specifically, it is proposed to use gradient-only techniques that do not use any zeroth order information at all for step discontinuous problems. A step discontinuous problem of note is the shape optimization problem in the presence of remeshing strategies, since changes in mesh topologies may - and normally do - introduce non-physical step discontinuities. These discontinuities may in turn manifest themselves as non-physical local minima in which optimization algorithms may become trapped. Conventional optimization approaches for step discontinuous problems include evolutionary strategies, and design of experiment (DoE) techniques. These conventional approaches typically rely on the exclusive use of zeroth order information to overcome the discontinuities, but are characterized by two important shortcomings: Firstly, the computational demands of zero order methods may be very high, since many function values are in general required. Secondly, the use of zero order information only does not necessarily guarantee that the algorithms will not terminate in highly unfit local minima. In contrast, the methodologies proposed herein use only first order information, rather than only zeroth order information. The motivation for this approach is that associated gradient information in the presence of remeshing remains accurately and uniquely computable, notwithstanding the presence of discontinuities. From a computational effort point of view, a gradient-only approach is of course comparable to conventional gradient based techniques. In addition, the step discontinuities do not manifest themselves as local minima. / Thesis (PhD)--University of Pretoria, 2010. / Mechanical and Aeronautical Engineering / unrestricted

The work deals with the design of a load-bearing wooden structure of a mountain hotel in the foothills of the Jeseníky Mountains. It is a building without cellar, two floors and a attic room. The floor plan of the building is 17 x 30 m with a porch of 3 x 10 m. Height of the building up to the ridge is 13.2 m. The design of the roof structure has been chosen from 2 different variants. Material usage consist of grown wood of class C24, glued laminated wood of class GL32h and steel S355. Static analysis was calculated by Dlubal RFEM software.

The diploma thesis is focused on the design of a new steel structure of a single-track railway bridge with bottom bridge deck. The solved bridge construction is located on line No. 123 between Nemšová and Trenčianska Teplá at the point, where the line crosses over the river Váh. The existing bridge on the line has a span of 50 + 50 + 50 + 50 m. The assignment was processed in five variants of a steel bridge structure with a bottom orthotropic deck. Each variant has a different static system, a different number of fields and a different type of superstructure. The comparison of variants was performed using multicriterial evaluation based on selected criteria. The most suitable variant was elaborated in more detail. The calculations were performed according to valid ČSN EN standards.

The subject of this master’s thesis is to design the supporting steel structure covered pedestrian bridge between the learning area buildings A and D of the Faculty of Civil Engineering, street Veveří 95 in Brno. The construction is designed as a bridge rod spatial structure with two main girders. The girders are a combination Vierendeel girder and truss structure. The girders are connected at the level of the upper and lower band by a crosspiece. The horizontal stiffness of the upper and lower surface structure is ensured by bracing. The upper surface of the pedestrian bridge is horizontal in the longitudinal direction. The lower surface of the pedestrian bridge is curved in order to overcome the difference in height between buildings A and D. This solution is the result of comparison an evaluation of three alternative solutions.

This work is dealing with accessibility of area that is on the border of three subsystems that are blocked off by each other by topography. Unfulfilled potential caused by barrier disabling connection to the city structure. Relief of a city influencing reachability of its parts that causes its decline. Overcoming such a barrier could cause activation of the area without big intervention to the urbanity or function of given area.
