New statics software for the pipeline and precast construction
With the new program application for precast girders the series of RIB software solutions with intuitive user prompting and economic dimensioning continues. The new program “Fermo” permits direct access into the dimensioning of reinforced concrete and prestressed prestressing bed girders optionally with cast-in-place concrete for structural engineering and bridge construction.
If necessary, the two entry level versions can be enhanced by additional modules for verifying the tilt stability and fatigue as well as for a subsequent single stage or two stage prestressing. Additional enhancement options for structural engineering and bridge construction permit the corresponding expansion to the full version. Through the configuration of the program environment, functionality and results output for predimensioning, short, long and detailed lists the program remains clear and efficient. “Fermo” will be available from the 2nd quarter of 2018.
New dimensioning verifications introduced
In addition to the adjustments to Guideline DWA-A 127 the program “Rohr” (Pipe) has been upgraded in version 18 with the current enhancement for the dimensioning of liquid soil. Liquid soil can be used advantageously in civil engineering and road construction when it is a matter of filling pipe trenches self-compacting and expeditiously and keeping subsidence at a minimum.
Along with the expansion of the load and calculation approaches for sometimes fluid, self-compacting backfilling materials (ZFSV) new verifications for the dimensioning of the pipes have also been introduced. This also includes verifications of the flowability and sedimentation tendency of the liquid soil as well as verifications for the self-compacting and a possible reexcavation. Product manager Stefan Kimmich: “Meanwhile different manufacturers are offering fluid backfilling materials with certificates of the BÜV-quality monitoring. It is to be expected that with the release of the new DWA-A 127 this new building materials technology will continue to advance.”
