Penstock
The Penstock program provides an analysis of a steel penstock that is generally in accordance with ASCE Steel Penstocks 2nd edition.
Caution and good engineering knowledge should be used in the selection of parameters as well as the interpretation of the results.
The program is divided into standalone sections as follows:
Caution and good engineering knowledge should be used in the selection of parameters as well as the interpretation of the results.
The program is divided into standalone sections as follows:
Considers the design of a manhole opening in the penstock in accordance with the requirements of ASME Boiler and Pressure Vessel Code.
Considers a section of expsed penstock beween two anchor blocks consisting of one expansion joint and several supports. The expansion joint may be either sleeve type or bellows type. Supports may be either ring girders or saddle supports.
Considers a steel tunnel liner that is embedded in concrete. The design is checked for internal pressure (load sharing with rock) and external pressure (buckling).
Considers the design of penstock trifurcations, or symmetric wyes or asymmetric wyes as detailed by USBR - Stress Analysis of Wye Branches by F.O. Ruud.
Considers the efficiency of a various configurations of riveted joints.
Considers the desing of a buried penstock subject to various loadings including backfill weight, live loads and internal vacuum. ASCE Manual No 119 and AWWA M11 are used for reference.
Considers the design of flanges in accordance with the requirements of ASME Boiler and Pressure Vessel Code Appendix Y. All three classes and all three categories are considered.
Considers the design of flanges in accordance with the requirements of ASME Boiler and Pressure Vessel Code Appendix 2. This includes all flange style shown by Figure 2-4 of ASME.
