The Maari DrillACE Well Head Platform (WHP) was installed offshore New Zealand during the second quarter of 2008 for the designated operator OMV New Zealand Ltd. The platform was engineered and designed by Arup and Clough. Clough was responsible for engineering, procurement, construction and installation activities on the project, with Arup undertaking the design of the primary steel structure, including the plated base, deck and tubular jacket. The Maari WHP was the third ACE platform and the second DrillACE platform to be installed. This paper considers a number of the unique features of the structural design of the Maari DrillACE platform that were encountered during this project as well as providing a background on the ACE platform concept.

The paper deals with the design of steel structure of the temporary footbridge, intended especially for the usage in the construction site for pedestrian and bicycle traffic. In the period of last two years, on the authors workplace, in the co-operation with the mounting company, the new type of steel footbridge is being developed. Within this development the attention is, among others, paid to the structural design, in particular to the harmonization of static solution and structural detailing, to achieve the efficient design. In the course of solving this problem, two types of the footbridge are being developed in parallel. Both footbridges are composed as the structures with a lower deck, truss main girders and bracings; the first structure (short footbridge) with a small self-weight may have the span up to 18 m; the second structure (long footbridge) with a normal self-weight may have the span up to 36 m. The paper is focused on the brief description of structural composition and parameters of the short footbridge, as well as structural detailing of the joints of main load-carrying parts. The configuration of the whole structure and individual structural details have been designed with respect to the static, dynamic and fatigue affects, which have been experimentally verified using loading tests of the footbridge prototype with the span of 18 m and fatigue tests of significant structural details.

<p>Numerical optimization has a large potential in the context of structural design, but practical applications remain scarce. Even metaheuristic algorithms, which are easy to use, are rarely adopted in practice. Possible explanations are the fact that for problems with many design variables, metaheuristic algorithms converge slowly, and that structural optimization often leads to very complex structures, resulting in a high construction cost. The aim of this paper is to illustrate the potential of numerical optimization in a realistic design context. The focus is on the steel structure of the Ghent Market Hall, which is redesigned using a genetic algorithm. The structural member groups from the original design are maintained, such that the number of design variables is sufficiently low, and that the complexity of the design remains limited. Using this approach, a design is obtained that consumes 15 % less material than the original design.</p>

This project is the construction project of the academic report comprehensive building of the Central Youth League School. The main function of the project is the academic report room, including an 800-person lecture hall, a 300-person multi-function lecture hall, a 500-person multi-function lecture hall, an exhibition hall, etc., and three underground floors. There are three floors above the ground, and one floor is partially high. There are 12.8, 13.8, 15.7, 18.2, 18.6, 20.8, 27.8 meters in the sub-regions of the roof structure elevation. This article introduces the structural system, the judgment of structural out-of-limit situations, prestress design, steel truss design, suspension steel structure design, cantilevered large-span concrete beams, etc., through a variety of structural calculation and analysis methods, and find out structural weaknesses, and adopt Corresponding seismic strengthening measures, the calculation results show that the structure has good seismic performance and can meet the requirements of the code.

Asymmetric Loadings

A new strut‐framed beam steel structure is considered. This type structure is employed in reconstruction of pedestrian bridges. The proposed constructional design model allows replacing the two‐span beam bridge by one span strut‐framed beam. In this case the members of already existing carrying structure are employed and the service of the actual structure is not interrupted. A response of new structure to symmetric and asymmetric loadings is analysed. The analytical relations for distribution of internal forces are presented. The choice of parameters of strut‐framed beam is investigated. An efficiency of suggested structural design model is illustrated via the performed numerical simulation of strut‐framed beam.

Abstract The paper follows the paper describing the condition of wrought iron structure of main railway station [1]. In this paper the investigation of condition of paint system corrosion surface treatment is given and the restoration procedure is described. The withdrawal samples of paint systems were analysed by stratigraphy, FTIR and XRF analysis. Due to identification of Pb pigment presence in primer the water jet technology was chosen which minimalised the danger waste formation.
