Fujita, Masanori; Sakai, Junpei; Oda, Hirotaka; Iwata, Mamoru | Building system for a composite steel-timber structure | Steel Construction | 3/2014 | 183-187 | Articles |
KurzfassungIn order to address global environmental issues, there is an urgent need for the building structure field to use as much timber as possible to contribute to reforestation, as well as to research and develop a building system that does not diminish the structure’s functionality and safety [1]. The building structure field is required to actively use this wood as timber, but the timber is too weak to use for large buildings. Research and development of an appropriate building system that can utilize such timber is necessary. x | |||||
Kummerer, Clemens | Building protection for the inner city tunnel excavation for the Metro in Rome / Bauwerksschutz für den innerstädtischen Tunnelbau am Beispiel der Metro in Rom | Geomechanics and Tunnelling | 5/2013 | 464-470 | Topics |
KurzfassungFor the construction of the Metro B1 line in Rome, special settlement reduction measures were implemented for settlement-sensitive structures beside deep excavations with depths of up to 45 m. These measures were necessary due to the excavation of tunnels with 6.8 and 9.8 m diameter under challenging soil and groundwater conditions. The originally designed jet grouting bodies were replaced by compensation grouting. This enabled all works to be performed from eight shafts (maximum 24 m depth), limiting the public space requirement. The efficiency of compensation grouting was demonstrated in two full-scale field trials and the advantages of active settlement compensation were proved during tunnel excavation. x | |||||

KurzfassungThe contribution takes a glance at the application of BIM technologies in the design and construction phases of shield tunnelling projects. The intention is to show how Building Information Modelling can be translated into actual benefit, not only in the operation phase but also in the design and construction phases of bored tunnels. Emphasising the integrative character of referencing data uniformly in space and time, examples are given of seamless communication between 3D geometrical modelling, efficient numerical simulation and model adaptation based on measured data acquired during the boring process. The article covers the complete range from predesign through structural analysis and detailed design until the actual excavation process including its interactions with the environment. Special emphasis is given to data management, which is the key to transforming a mere 3D visualisation into a Building Information Model. The article therefore presents a concept for database-supported, web-based integration of software modules for geometrical modelling in various levels of detail, efficient numerical simulation tools that are based upon this representation, and process controlling that manages all data acquired during the construction process in a spatially and temporally coordinated reference system. x | |||||
Ehrbar, Heinz | Building Information Modelling - A new tool for the successful implementation of major projects of German railways / Building Information Modelling - Ein neues Werkzeug zur erfolgreichen Realisierung von Großprojekten der Deutschen Bahn | Geomechanics and Tunnelling | 6/2016 | 659-673 | Topics |
KurzfassungIf correctly applied, digitalisation can also create great added value for railways, which explains why German Railways (DB) is taking it seriously. As with many other construction client organisations, the DB with their portfolio of major projects was and is confronted with the situation that cost targets and deadlines can often not be maintained. The causes for such deviations are various and in addition to the many external reasons, are also due to the current methods of controlling construction projects. The DB has recognised that the use of digital methods of project implementation such as Building Information Modelling (BIM) can achieve a great contribution to the improvement of project stability. While DB has already consistently furthered the use of BIM for station buildings in recent years, BIM has only been in use on DB infrastructure projects since 2015. By the end of 2020, however, the running up process of BIM at DB should have reached the stage that all complex major projects and all projects suitable for standardisation are designed and controlled with BIM. The DB hopes to gain from the use of BIM more transparency on projects, considerable economic benefits and the strengthening of the collaboration of all sides as partners. x | |||||

Malkwitz, Alexander; Ehlers, Johann | Building Information Modeling (BIM): Vision vom digitalen Bauen | UnternehmerBrief Bauwirtschaft | 1/2014 | 3-8 | Berichte |
KurzfassungWas in anderen Industriezweigen schon lange genutzt wird, findet langsam den Weg in die Bauwirtschaft. Das digitale Bauen und Simulieren von Herstellungsprozessen wird in der Automobil- und Flugzeugwirtschaft seit Jahren erfolgreich angewendet. Eine ähnliche Methodik ist in der Bauwirtschaft und damit in der Unikatherstellung ebenfalls möglich. Das so genannte Building Information Modeling (BIM) bildet eine neue Methodik ab, mit der der gesamte Lebenszyklus eines Bauprojekts abgebildet wird. Von der Idee bis hin zum Abriss können alle Information des Gebäudes in einem virtuellen Modell hinterlegt und transparent dargestellt werden. Die Autoren erläutern in unserem UBB-Hauptaufsatz, was BIM eigentlich ist und berücksichtigen dabei auch rechtliche Fragestellungen. x | |||||
Kollegger, Johann; Foremniak, Sara; Suza, Dominik; Wimmer, David; Gmainer, Susanne | Building bridges using the balanced lift method | Structural Concrete | 3/2014 | 281-291 | Technical Papers |
KurzfassungThis article explains the process of developing a new method, called the balanced lift method, for constructing bridges based on an alternative to the bridge construction techniques used nowadays. The most common methods of building bridges are those using falsework or the cantilever method, but a rather uncommon method, the lowering of arches is seen as the origin of the balanced lift method. The idea was to create a method that would allow a bridge to be built in a very fast manner without the need for falsework, using prefabricated elements and assembling all parts together in a position - in this case vertically - that would simplify the construction process. In order to reach the final state of the bridge, the parts assembled vertically are rotated into their final horizontal position. This article contains descriptions of the development of the method, a large-scale test and two bridges already designed using the balanced lift method. x | |||||

Iwata , Mamoru; Midorikawa, Mitsumasa; Koyano, Kazuhisa | Buckling-restrained brace with high structural performance | Steel Construction | 1/2018 | 3-9 | Articles |
KurzfassungThe authors have studied the buckling-restrained brace providing a stable hysteretic characteristic even under high-strain conditions. The structural performance of the buckling-restrained brace is represented by the evaluation formula that is the lower limit of the cumulative plastic strain energy ratio. However, as earthquakes are becoming much longer, so it is necessary to research and develop a new buckling-restrained brace with a higher energy dissipation capacity. In this paper, our past studies are reviewed and the conditions of high-performance of buckling-restrained braces extracted. The buckling-restrained brace considered was tested. As a result, a buckling-restrained brace with a larger cumulative plastic strain energy ratio is proposed. x | |||||
Mendera, Z. | Buckling Strenght of Tapered Steel Columns (Zur Knickfestigkeit sich nach oben verjüngender Stahlstützen). | Stahlbau | 4/1995 | 113-118 | Fachthemen |
KurzfassungEs wird der Versuch unternommen, die Rechenarbeit zu reduzieren, die für Stützen entsteht, deren Trägheitsmoment sich linear ändert und deren Querschnitt entsprechend variiert. Das kann durch ein - zu normendes - Rechenverfahren geschehen für Druckstäbe mit konstantem Ie und konstanter Querschnittsfläche Ae. Die bisherigen Forschungsarbeiten sind brauchbar. Die Computersimulation fürhrte zu Ergebnissen für kritische Knicklasten Ncr für einige Stützenformen mit stetiger Verjüngung in folgenden Kombinationen: nichtkonstantes Trägheitsmoment bei konstanter Querschnittsfläche; I-Querschnitt mit nichtkonstantem Trägheitsmoment und nichtkonstanter Querschnittsfläche; Rohrquerschnitt mit nichtkonstantem Trägheitsmoment und nichtkonstantem Querschnitt. Es werden aus den Analysen neue Formeln entwickelt für die Berechnung der Trägheitsmomente Ie von Stützen mit gleicher kritischer Last wie Stützen, die sich stetig linear verändern und nach der Stabilitätsgleichung für Druckstäbe mit variablem Trägheitsmoment berechnet werden. Die vorgeschalgene Formel für Ie wird durch numerische Simulation abgesichert. x | |||||
Buckling resistance of longitudinally stiffened panels with closed stiffeners under direct longitudinal stresses | Stahlbau | 1/2023 | 48 | Empfehlungen der Redaktion | |
Pourostad, Vahid; Kuhlmann, Ulrike | Buckling resistance of longitudinally stiffened panels with closed stiffeners under direct longitudinal stresses | Steel Construction | 4/2022 | 229-243 | Articles |
KurzfassungThe buckling behaviour of panels may be determined according to EN 1993-1-5 [1]. Most of the design rules relating to stiffened panels in EN 1993-1-5 were derived on the basis of open-section stiffeners. Several recent investigations have shown that the application of the design rules according to EN 1993-1-5 considering the torsional stiffness of the stiffeners may overestimate the resistance of the panels. Therefore, the recent Amendment A2 to EN 1993-1-5 states that the torsional stiffness of stiffeners should generally be neglected in determining critical plate buckling stresses. In addition, prEN 1993-1-5 [2] provides rules for considering the torsional stiffness of stiffeners. However, in this article it is shown that even the rules of prEN 1993-1-5 are not sufficient to overcome the safety deficiencies. The article focuses on the investigation of the buckling behaviour of stiffened panels with closed-section stiffeners subjected to constant longitudinal compression stresses. Improved rules have been developed that allow to consider the torsional stiffness of the stiffeners. Based on an extensive numerical parametric study, a new interpolation equation between column- and plate-like behaviour is proposed. In comparison to [3], the investigations have been extended to the effective width method. They show that the proposal provides a safe and economic solution for the reduced stress method and the effective width method when considering the torsional stiffness of stiffeners by calculating the critical plate buckling stresses. x | |||||
Fajuyitan, O. Kunle; Sadowski, Adam J.; Wadee, M. Ahmer | Buckling of very short elastic cylinders with weld imperfections under uniform bending | Steel Construction | 3/2017 | 216-221 | Articles |
KurzfassungThe length-dependent behaviour domains of thin elastic cylindrical shells under uniform bending have recently received significant research attention. Ovalization is known to affect very long cylinders that undergo significant cross-sectional flattening before failing by local buckling. This effect is restrained by the end boundary conditions in shorter cylinders, which instead fail by local buckling at moments close to the classical analytical prediction. In very short cylinders, however, even this local buckling is restrained by the end boundary, and failure occurs instead through the development of a destabilizing meridional fold on the compressed side. Although this is a limit point instability under bending, ovalization does not play any role at all. This 'very short' length domain has only recently been explored for the first time with the aid of finite element modelling. x | |||||

Misiek, T.; Krüger, H.; Ummenhofer, T.; Kathage, K. | Buckling of stiffeners for stainless steel trapezoidal sheeting | Steel Construction | 4/2010 | 225-230 | Articles |
KurzfassungThe calculation of the loadbearing capacity of thin-walled structures, including trapezoidal sheeting, normally follows the procedures of EN 1993-1-3 and similar codes. EN 1993-1-4 complements this standard for thin-walled structures made of stainless steel. Unfortunately, a buckling curve for stiffeners between the plane cross-section parts of the flanges or the webs is lacking. A finite element analysis was performed in order to obtain a buckling curve for such stiffeners. The finite element model was calibrated based on test results and by recalculating the EN 1993-1-3 buckling curve for the stiffeners in trapezoidal sheeting made of non-alloy structural steel. The results of the research into the loadbearing behaviour of thin-walled stainless steel trapezoidal sheeting presented here are closing this gap: the proposed addition to the design formulae means it is now possible to carry out a complete calculation of the loadbearing capacity of stainless steel trapezoidal sheeting. x |
