Wiki Page: 01. Does AutoPIPE calculate seismic loads according to the EN 1998 codes ?
Applies To Product(s): AutoPIPE Version(s): 2004, XM, V8i Environment: N/A Area: Subarea: Original Author: Bentley Technical Support Group Date Logged & Current Version Jan 2015 09.06.01.10 Problem: I would like to know if AutoPIPE calculates according to the EN 1998 codes which is needed for Bulgaria? or can I convert information between codes. please let me know since this is critical for the approval for the engineering. Answer: AutoPIPE is able to model various Seismic Earthquake loads as mentioned above. With regards to the Static Seismic analysis feature, AutoPIPE V8i 09.06.00.xx has 5 different codes available: ALA (ASCE 2002) ASCE (2010) GB50011 - 2001 Mexican CFE 2008 User As seen above, En1998 code is not a selection. However, the user can get the code values from another resource and enter them in as a "User" code type. See AutoPIPE online help for details on this feature. The following enhancement has been logged (TFS-E97721: Add new Seismic code, EN 1998) to add this new seismic code to a future version of AutoPIPE.

Wiki Page: 02. Can we apply a 3-dimensional earthquake combination in AutoPIPE?
Applies To Product(s): AutoPIPE Version(s): 2004, XM, V8i Environment: N/A Area: Subarea: Original Author: Bentley Technical Support Group Date Logged & Current Version Jan 2015 09.06.01.10 Problem: Can we apply a 3-dimensional earthquake combination? some believe that enveloping two planar earthquake combinations (X/Y and Y/Z) is still two dimensional. Answer: This goes back to what is the requirement that is laid down by the standard which the user's are following. For example, look at the following diagram from our online help for JSME 2008: For JSME 2008, AutoPIPE provides the option to "apply all three directions at the same time", which can be checked or unchecked. You can see that for the dynamic seismic analysis it is considering R1, R2, and R3 (all three directions) to reach a D1xyz (dynamic in x, y, and z direction). However, you can also see that for static analysis, x combined with vertical y and z combined with vertical y. Now these requirements are derived from JSME 2008. Whatever project the user is working on, he should refer to what are the requirements laid down by the standard that they want to follow.

Answer: Suggestion is to correctly apply the following 3 items to the piping model: A. Insert> Xtra Data> Hydrodynamic Data B. Load Buoyancy C. Load Response Spectra It will be important to include added mass coefficient (Ca). This will impact the calculated frequencies for modal analysis, which in turn will be used in the Response Spectrum analysis. The user will have to come up with an approximation of what type of hydrodynamic loading (waves) may be generated by the seismic activity. This again will then need to be incorporated in the model using the Wave loading. Buoyancy loading will need to be applied separately to calculate the lift forces.

Wiki Page: 06c. How to model a liquid (water) / gas (foam or air) Fire Protection piping system in AutoPIPE?
Applies To Product(s): AutoPIPE Version(s): 2004, XM, V8i Environment: N/A Area: Subarea: Original Author: Bentley Technical Support Group Date Logged & Current Version Jan 2015 09.06.01.10 Problem: How to model a liquid (water) / gas (foam or air) Fire Protection piping system in AutoPIPE? Answer: AutoPIPE is concerned only with the integrity (Stress) design of the system against specific design codes for various loading conditions and is typical of most Pipe Stress programs. The additional built in fluid transient capability of AutoPIPE provides the fluid transient loads at direction/size changes for valve opening/closing events. It has a simplified pessimistic approach and calculates the Joukowski pressure surge for rapidly opening/closing valves and the dynamic effect as the pressure wave travels round the pipe. It does not account for any complex flow conditions and has no reflected wave or multiphase capability. Use the link to view the seminar to help explain the capability: http://pages.info.bentley.com/videos/?Filter=AutoPIPE . At this time AutoPIPE unable to handle this very complicated mixed condition of compressible (air) and incompressible (water) fluids by itself. However, for AutoPIPE fluid transient to work the contents have to be either all fluid or all gas (i.e. single phase). This flow condition is something for a CFD problem for a complex fluid flow program like ANSYS, FlowMaster, PipeNet. Fire protection systems are generally cold and have only weight and pressure considerations for analysis. Where systems are simple then normal support spanning and hand calculations could suffice, but it could also be analysed using AutoPIPE. If the CFD programs are used and can produce the time history inputs then you could use AutoPIPE to stress analyse the flow events.

Wiki Page: Errors while executing strength calculation for double fixed tubesheet heat exchanger
Designing a double fixed tubesheet heat exchanger is challenging and complex since various design cases need to be considered while determining the tubesheet thickness including differential thermal expansion between the shell and tube sides. Shown below is a simple NEN type double fixed tubesheet exchanger modeled using AutoPIPE Vessel and as one can see there are several errors reported: The errors reported are as follows: 25: insufficient strength in shell-channel joint 27: longitudinal membrane strength in tubes exceeded 28: longitudinal membrane stress in shell exceeded 633: tube-to-Tubesheet joint strength not adequate Also the thickness of the tubesheet is excessively high at 278 mm. There may be several ways to resolve each of the above errors individually and onus lies on the designer what method he may want to choose. However, one of the most commonly used methods for resolution of these types of tubesheet related errors in double fixed tubesheet exchangers is by including an expansion joint, since most of the time the tubesheet related errors in double fixed tubesheet may be due to stress arising out of differential thermal expansion between the tubeside and the shell side. The expansion joint can be added by clicking on the icon and entering the spring rate in the dialog box that appears as shown below, there are also options for flanged and bellows expansion joint: NOTE - Determining expansion joint spring rate is the complete responsibility of the designer based on the expected mean metal temperatures of the shell side and tube side during various operating scenarios - the spring rate entered (200 daN/mm) is just for example : Note that the location of the expansion joint can be entered in the dialog box, however it can be moved in the 2D sketcher directly by selecting the component, right click and selecting the option "Move". The strength calculations are performed once again and as shown below there are no errors this time and the expansion joint is shown clearly. The design is complete. Observe that the thickness of the tubesheet is also significantly reduced (24 mm) thereby leading to an optimized design: In the report, the calculation of the tubesheet shows clearly the inclusion of the expansion joint spring constant (200 daN/mm or 2,000 kg/mm):

Answer: Please see the following AutoPIPE help section: Help > Contents> Contents Tab> Bentley AutoPIPE> File Reference> Working Directory Files Each of the files listed in this subsection are stored in the current working directory. The working directory is established from the directory where the file was created/opened using either the File/New or File/Open commands. Otherwise, AutoPIPE places each of them in the program directory. The file name for all permanent, unformatted files is the same as the name of the model. Other file names are as noted. Unformatted Working Directory Files Formatted Working Directory Files The most import file types are the model *.DAT and *.CMB with the model's specified library files. All the other files in the model directory are created after applying loads, analyzing the model, and reviewing results. However, if the certain files are deleted from the directory the analysis results will be different. Example: Person A created a model that had performed a fluid transient analysis and created an Output report. Person A sends only the *.DAT and *.CMB files to Person B who plans to recreate the original results. Person B opens the model and runs the analysis. However, the results does not include the time history results, why? The reason is because the THL and TIH files were missing from Persons B file directory. These files are automatically created by completing the Load> Fluid Transient dialog screen. The correct procedure would be to select File> Model Management> Save Archive. This will create an *.APC file. This single file will contain all the files require to run the analysis correctly. Note, an *.OUT file is only used to review the output results.
