The objective of this thesis is to develop a precast and prestressed concrete design for a factory hall, which was initially planned as a steel structure. Furthermore, a structural analysis is conducted on several chosen structural elements according to the European Standards and the German Annexes respectively. The analysis is done both by manual calculation and software calculation for comparison and includes the ultimate limit state design, the serviceability limit state design and the design for the state of transportation and assembly of the precast members. Lastly, to illustrate the results of the analysis, an overview drawing with the new concrete design as well as formwork and reinforcement drawings for each of the analyzed structural members are developed.

The earth pressure acting on the wall of a Rahmen bridge generates significant bending moments at the corners. These moments create problems in the wall in terms of stability and economy. In this study, a Rahmen bridge with an open wall was adopted to solve the problems highlighted above, and its optimal opening rate was estimated. Structural analysis was performed for 36 analytical cases by applying the limit state design method according to lengths of 20 and 15 m for the closed height ratio (h/H) and closed width ratio (b/B) of the wall. Within the scope of this study, in the Rahmen bridge with a 20 m span, it is desirable to design an open wall to satisfy the 0.4 ≤ h/H ≤ 0.614 and 0.75 ≤ b/B < 1 conditions when adequate reinforcement is provided at the wall end in contact with the haunch. Additionally, an open wall should be designed for the 15 m span Rahmen bridge to satisfy the conditions of 0.229 ≤ h/H ≤ 0.586 and 0.833 ≤ b/B < 1 when suitable reinforcement is provided at the slab end in contact with the haunch. Therefore, the Rahmen bridge with an open wall can be used instead of the conventional Rahmen bridge, considering the economy and on-site applicability factors.

Pipeline Design

This paper considers the application of the limit state philosophy of structural analysis to pipeline design. General aspects of the philosophy are discussed and the approach to the evaluation of safety factors is reviewed. The paper further considers the various limit and serviceability states which would be relevant to a pipeline and reviews the various factors which may require consideration, before a code embodying the limit state philosophy could be formulated. A review of the state of current knowledge on various aspects of geometry and material characteristics, loading and structural behavior is presented. It is intended that such a review can be used as the basis for a larger study to provide guidance and data for the evaluation of rational levels of safety factor. The major conclusion reached by the authors is that a limit state philosophy would be valuable in providing a suitable framework, which may highlight the significant aspects of pipeline design and which can most easily accommodate new requirements and results obtained from research.
