KurzfassungThe new intercity line Toluca - Mexico City has a length of 57.7 km. The daily passenger estimate is about 230,000 to 300,000. The investment volume amounts to 2.5 bn US$. Its special feature is the MAURER seismic protection system for two long viaducts. The company installs for this purpose so-called guided cross-ties, the first absolutely earthquake-proof railroad bridge expansion joints. Together with a complex system consisting of bearings, dampers and elastomeric spring isolators they ensure structural stability, function and safety for various load cases: from braking and acceleration forces in normal operation to the Maximum Considered Earthquake (MCE). MAURER startet to work for this project in 2016. The last step scheduled is the installation of the guided cross-ties at viaduct 4 in the third quarter of 2020. (© MAURER SE) x | |||||

KurzfassungIndustrial storage operators use not only new pallet racking systems, but also old ones for which certification documents possibly do not exist. In order to check the carrying capacity of such racks, in addition to component tests, full-scale experimental tests were carried out on complete structures to help the development of reliable numerical models. The racks were subjected to vertical and pushover loads in the laboratory using an improved version of the base plates to achieve fixed support conditions. Vertical loading was imposed by filling tanks with water, an operation that was activated and controlled through an innovative hydraulic network specifically designed for this purpose. During the vertical loading tests, a moderate earthquake took place near the experimental facility and this influenced the rack behaviour positively. The spine brace was too flexible in the out-of-plane direction and did not participate in the resistance to lateral forces. Distortional buckling of the columns was observed at high lateral loads. The experimental tests allowed the calculation of conservative values for the behaviour factor q. x | |||||
Dulevski, Encho | Effective widths for class 1 and 2 composite girders at negative moments | Steel Construction | 3/2019 | 243-248 | Articles |
KurzfassungWhen ascertaining the effective widths of class 1 and 2 composite girders, it is claimed that at ULS, Eurocode 4 procedures give highly conservative results. A new approach to the problem is proposed in which the strain limitation values are introduced after deriving a new formula (graphically presented) with the intention of replacing the existing one. It turns out that the new effective width is significantly larger. Such a result leads to some advantages in reinforcement distribution in the support areas of continuous girders. It might also lead to some savings in reinforcing and structural steel. This is demonstrated by an example. Another example shows a situation in which the rough application of Eurocode 4 may produce a design with a lack of reliability for some of the bridge superstructure elements. The results obtained may also be useful for situations where a structure with composite girders already in service has to be redesigned for increased loads. x | |||||

KurzfassungMOCAPE in Shenzhen/China, housing the Museum of Contemporary Art (MOCA) and the Planning Exhibition (PE) is a vast building consisting of many long-span structural elements. The transparent façade highlights the main entrance and circulation zone between the two buildings and allows unobstructed views between the inside and outside. The open, column-free exhibition areas with heights from 6 to 17 m also strengthen the impression of a generous design concept. x | |||||

Schäfer, Markus | European design code for composite structures in steel and concrete - Historical development and investigation in the second generation of Eurocode 4 | Steel Construction | 2/2019 | 70-81 | Articles |
KurzfassungThe Eurocodes (EC) represent European norms (EN) for the design and construction of building and bridge structures. The development of these European design codes is carried out on behalf of the European Union (EU) by the “European Committee for Standardization - CEN”. The Eurocodes have been in use for some years now. The motivation behind the development of the Eurocodes is the harmonization of the planning and design process for the structural components and construction elements of buildings and bridges all over Europe. Based on the experience gained through the use of the Eurocode conditions in recent years and many comments from industry, a revision of all parts of the Eurocode is currently in progress. The aim is to adapt the current design standards to the state of the art and research, to simplify the application and to harmonize the Eurocodes with each other. Finally, these modifications will be transferred to the second generation of European standards. An overview of the development phases and project teams is presented in this paper, accompanied by an insight into current standardization work and the technical discussions, mainly focusing on EN 1994-1-1. x | |||||

Nie, Jing; Sugimoto, Hikaru; Ono, Kiyoshi; Miyashita, Takeshi; Matsumura, Masahide; Okada, Seiji | An experimental study on the local buckling strength of an SBHS700 stub column with cruciform section - With an overview of the mechanical properties of SBHS700 | Steel Construction | 2/2019 | 82-90 | Articles |
KurzfassungRecently, SBHS (Steels for Bridge High-Performance Structure) has been introduced in Japan because of its remarkable mechanical properties. The main features of SBHS are high yield strength, improved toughness and weldability, which are superior to conventional steel materials at the corresponding tensile strength grades. In this study, these material properties of SBHS were compared with conventional steel materials through experimental studies as well as the Japanese design specifications. The main focus of this paper is the evaluation of the local buckling strength of two SBHS700 stub columns, each with cruciform section through compression tests. The load-displacement relationship, strain bifurcation related to plate buckling and out-of-plane deformation are discussed. Two test specimens with different width-to-thickness ratio parameters RR are compared. As the results indicate, for the specimen having a larger RR, an abrupt decrease in load was observed after the peak load, whereas the decrease in load for the specimen with a smaller RR proceeded gradually after the peak load with a much larger vertical displacement. In terms of local buckling strength, it was found to be possible to evaluate the SBHS700 stub column with cruciform section based on the existing ultimate strength curves. x | |||||
