SAP Import Export Problem SAP Import and Export $2k File Today I faced a very strange problem in CSI SAP. Have you ever faced such a problem in your structural analysis tools? Same model file was used which yielded different results under following 2 scenarios:- 1) 1-The original file was run in SAP. 2) 2- Then this file was exported in text format and imported again. Value of TIME PERIOD of both the models were different and we found out that there is about 300kN difference in Self Weight of elements. I examined both the text files in MS WORD Compare Document feature and found out that a beam having depth of 700mm has been added in new model (model based on importing the text file) on various locations other than the original one. While in the model when I showed selection only for this 700deep concrete beam I found it to be everywhere in the model. I will explain the solution of the problem in next lines. Actually the original model exported from ETABS to SAP so I cannot confirm whether all this discussion holds good too for the models originally created in SAP or not? Actually there were some NULL lines (created originally in ETABS) in the model. When you export the model as a text file and import it back it does not recognize the NULL lines but rather it applies those elements the first available section which in my case was 700mm deep concrete beam. So that’s why I got 300kN more self weight in the model due to these beams. So next time you export your model to SAP and send its text file for review to another person or firm, be informed that it will give them wrong results. So always send them SDB file.

Dear Umar, the admin! here are some of my suggestions i would like to include in our forum to make it more unique! we need a section called Trusted or Solved Examples or Learning Tutorials in which we can have subsections like ETABS, SAFE, STAAD, SAP etc... or by topics e.g. FOUNDATIONS, SLABS, FEM understanding, Intrepretting results of FEM etc i think by subject is better. Now every one can submit an example. After verifying the examples by us or other members, we can make it public on forum, so that it helps new learners of FEM softwares to download and understand it. I think this is the unique thing i havent seen in other forums even in very famous international forums... 2-We need a new section called Model Review...If any one wants to ask to review his/her model. They can upload it and after checking we can upload it back so that they can learn! again unique feature. By the way its all time consuming but i assure you i can go far with that concept personally 3-New section for developing new design sheets, vba programs, writing new articles or books and authors asking for help for joint writing. like i want my self some one who can assist me in make a new book on etabs. but unfortunately i had been very busy. but tomorrow my current projc gonna finish so i will think abt it seriously! 4-Need a new section for assisting structural programs like CAD, REVIT etc where we can share LISP files..by LISP files i dont mean the drafting help files, i mean rather pure engineering or related to engineering work files and stuff and tricks 5-Now i think we need atleast two moderating members to just arrange topics and threads and warn members for not posting in right section. They should develop the appropriate policies and upload on our forum and then appropriate authorities given to those moderators. 6-I dont know if we have a image host or not..if we dont we need one! I will add more but for the time being thats it lets have a discussion public or private...to consider these!

The question asked by asadishaq has been moved to a new thread. http://www.sepakistan.com/topic/63-safe-iterative-uplift-analysis/ Its always a good idea for making a new thread and ask questions there. allows other members to look at it and search. Thanks Rana Waseem for reporting that.

I like it... yes its true Now see the images in sequence
