The results of three ultimate load tests and of an extensive numerical parametric study (finite element analyses) on the load-bearing behavior of corrugated web girders with square web openings are presented. Reinforced web openings are considered....

The hospital landscape in Germany is changing. The number of houses is declining and key indicators have changed. Forecasts assume that there will be further structural adjustments. A large number of megatrends can be identified as the causes....

Even within nominally homogenous soil layers, spatial variations of soil properties occur. Current design methods simplify varying soil properties by applying constant values. In order to achieve a reliable geotechnical design, the local variance of...

The CarboLight Bridge is part of the modernised exhibition in the “Deutsches Museum” in Munich towards future-oriented innovations. With a length of 9.5 m, the bridge is designed as a filigree structure consisting of two gently inclined V-shaped...

The sawcut depth of transverse contraction joints in jointed plain concrete pavements affects the crack induction in early age concrete and the states of stress around the contraction joints caused by temperature during operation. ...

Large construction projects in Germany are seldom completed within the planned timeframe and budget. The Integrated Project Delivery (IPD) model, which is a promising solution for the management of large construction projects, offers many advantages...

The use of Building Information Modeling (BIM) is becoming increasingly important in infrastructure planning. For example, public clients are more and more frequently demanding the use of BIM methods for planning services. However, there is still a...

A 60 years old sliding bridge over the 42 m wide strait of Euripos, Greece was evaluated. The evaluation comprised the riveted truss girder steel bridge and the two tunnels into which she slides. It includes collection of existing documents,...

Within the framework of ecological transition, new procedures for the assessment of existing buildings are developed as reflection of new values given to the preservation of existing – partially historic – structures. Ecological transition added...

The new underground station Elifelet in Tel Aviv got a membrane roof consisting of 38 sails. The requirements of shading, rain protection and simultaneous ventilation are fulfilled with the interlocking membrane panels above the platform opening. At...

Within the scope of the paper, a causal analysis is presented on the basis of data on cost increases in public, municipal building construction projects. The reasons for the cost increases are structured with regard to various criteria and...

The development of new high-performance materials and the use of additive manufacturing techniques opens up new possibilities in the field of construction. The Collaborative Research Center/Transregio 280 (SFB/TRR 280), funded by the German Research...

While productivity in the German economy as a whole has increased significantly over the last three decades, the construction industry has not seen any progress over the same period. Construction is still a highly individualized process with a low...
