In the case of using slow‑curing concrete (usually for thick components), you can reduce the calculated minimum reinforcement by a factor of 0.85 to apply the load due to restraint, according to EN 1992‑1‑1, Section 7.3.2. However, a precondition for reduction is that the characteristic value of the strength development r = fcm2 / fcm28 does not exceed 0.3. Other key requirements for the application of this reinforcement reduction are specified explicitly in the final planning documents.
Building Information Modeling is making headlines in building design. While some engineers only use BIM methods for planning, others are dealing with this topic for the first time or rarely have time for it in their daily working routine. However, one topic seems the most important in structural engineering: How can structural engineers benefit from BIM?
The proportion of glass used when planning a building is increasing. Open, light-flooded buildings represent the modern art of architecture. However, specialized engineers have to face new challenges during planning. One such example is ceiling-high glass facades loaded by a handrail. The influence of this loading, as well as the calculation of the deformation, are shown in this article.
This article discusses the most common BIM interfaces. Adjustments are often necessary during the transition to the structural branch-specific model. The tasks that arise and the tools to address them successfully and quickly are presented.
Building Information Modeling describes what is possibly one of the most important current topics in the entire construction software industry. However, the process is not that new, and it is a well-known fact that the total costs of a project can be positively influenced by good planning in the initial stage.
The transparency of the glass material should not be missing in any building. In addition to the typical application areas such as windows, this building material is increasingly being used for facades, canopies, or even as bracing of stairways. Of course, the planning architects often set a very high standard of transparency on fixation of the glass panes. This requires special glass fittings that couple the glass panes.
The increasing use of the BIM method in planning buildings also opens up new possibilities for structural engineers. Once a comprehensive 3D model of a building has been created, you want to continue using it for the structural analysis and gain the maximum benefit from it. However, there are also some new challenges for the structural engineer and the software used, which are described in this article.
Plan changes, even at an advanced stage of planning, or modifications of existing buildings are part of the daily routine of many structural engineers.
