The proposed TS defines rules for the design of high pressure piping for hydro-power plants (penstocks). It will cover the following topics:
- Scope of application; types of structures (above-ground and buried penstocks, encased pressure conduits) and pressure / diameter combinations covered.
- Reliability classification of penstocks and corresponding design requirements (partial factors, design combination of actions)
- Materials
- Specific Actions on Penstocks
- Structural Analysis; beam modelling, advanced modelling
- ULS Design: i. Plastic Collapse; ii. Cyclic Plasticity; iii. Buckling / Stability / Excessive Ovalisation (for buried pipes); iv.Fatigue
- SLS Design
- Design of Specific Components: i. Wye branches and manifolds; ii. bends; iii. thrust rings; iv. pressure tunnel linings (internal; external pressure);
