  3. Dear all,Please guide me in calculating the base shear as per euro code 8.In following a formula Sd(T1) value getting in term of (g), say 0.1g. Do I need to use Sd(T1) value as 0.1 or 0.1*9.81 =0.981 m/sec2 for base shear calculation in place if Sd(T1). Please suggest.Fb = Sd(T1).m.(Lamda)Eurocode ref image also attached for your ready reference. http://www.sefindia.org/forum/viewtopic.php?p=76915#76915Thanks,Regards,Saikiran Gone.

  5. Guys, Can anyone mail me the link aswell ? Thanks. Mail to: oyuksel@gmail.com
  6. Dear All, What DeltT value to be considered in global analysis of steel structure (in FEM software), if minimum temp = 8 deg c , Maximum temp = 42 deg c, Structure type = steel structure Environment = roof covered (not directly in contact with sunlight) I found following reference on google, please suggest me which is correct as per EN 1991 part5 (Thermal Actions) Example 1: T min = 8 deg c Tmax = 42 geg c Delta T = 0.5(42-8) = 17 degc Example 1: T min = 8 deg c Tmax = 42 geg c Delta T = 2/3(0.5(42-8)) = 0.67*17 = 11.4 degc Please suggest if any other correct procedure to calculate. Thanks, Regards, Saikiran Gone.

    Hi Reinisgailitis , Thanks for your info. Can please suggest which book/material to refer for deflection calculation of pile foundation. Regards, Saikiran Gone.
  9. Hi , Does anyone have an answer to the following question ? Maybe a similar example ? https://we.tl/Xd4nxFtzXL thanks,
  10. Calculating the bearing capacity of a spread foundation (according to EC7) is based on some parameters. 2 of the parameters are the width and the length of the foundation (and so the area). But are there any limitations on the width and length of the spread foundation that can be used. Lets says I have a building (lets say 20m x 20m) on a large "spread foundation" of 20m x 20m. Maybe this can be the bottom of a basement. Can I still use the same principals for calculating the bearing resistance of this large spread foundation?

    The force you're interested in getting the deflections for. Yes, if the moments is applied to the individual pile you should take it as the H=moment/eccentricity + usual H. If you need to know deflection under ULS loads you use those loads, if you need to know under characteristic combination then you take those. P.S. Broms method is an estimate, far from the most reliable/precise, so be aware. Cheers
  12. Dear Engineers, What is the force value to be taken for horizontal deflection of the plie foundation As per boorms method from Tomilson textbook, What H value to be taken for deflection calculation. Please find the attached images for your ready reference. Query: H value is the direct lateral force or moment also included. Please clarify. H = lateral force or H = Lateral force + Moment/eccentricity. http://www.sefindia.org/forum/viewtopic.php?p=76624#76624 Regards, Saikiran Gone.
  13. Thanks @dik & @ReinisGailitis for info. Regards, Saikiran Gone.

  15. Hello, Where can I find the downloads please? Can someone send them to my email-adres? info@lengco.be Thanks a bunch!!

  17. Hello all, I have posted the permissable allowable stresses when designing to british standard below. These are compared to unfactored loading.(Table 8 - BS 5268-2). I have also attached the eurocode characteristic strength table (Table 1 - BS 338) As you can see obviously the characterisitc values are higher when comparing to the permissable values in british standard. Well all apart from compression perpindicular to the grain. In BS Compression perpindicular to grain = 2.4N/mm2, In eurocode compression perpindicular to grain = 2.5N/mm2 (For C24 Timber). This does not make sense to me as we are comparing the chaacteristic value to a factored load and applying material factors so why would these 2 values be almost the same. This is a problem when designing stud walls to eurocode. Has anyone any thoughts on this and if their national annex is similar?
  18. Hello steven706, This type of bracing (concentric V bracing, according to eurocode's naming) is approaching in the chapter of concentric bracings in EN1998-1 6.7. This concerns, however, seismic design. If your design doesn't include seismic action you should refer to the general rules of EN1993-1-1.
  19. Hello In the playstore try : bouwenmetstaal greets
  20. Hi All, Do you have the design example for the Chevron Bracing according to EC3? or any book reference?
  21. Hello. Plastic analysis will be used. By restraint I mean support. For instance will the bases be of pin type connection? and do I have to put supports at the haunches locations to? I notice doing so will give me next to zero axial force in the columns while the buckling will be great if i put noting. so I'm rather confused how to obtain the forces required to to check the sections for compressinon, buckling and bending. Thankks
  22. What do you mean by restraints? Are you using elastic or plastic (non-linear) analysis?
  23. Thank you very much for this useful recourse. I'm now at the stage where I want to determine what forces the haunches must transfer. The method I'm using are finite element software. The only problem I have is wether I have to put restraint at the haunch connection or not prior to simulating the forces. What kind of restraints should i put there. Ofcourse the connection have to transfer moment and forces.
  24. Do you actually have an acting force in the x direction?
  25. hello evryone can you help me for following fin plate calculation. Plate is connection to rhs memeber through one bolt.
  26. Hallo. Check out steelconstruction.info for a lot of good information and many freely available SCI publications. Good luck!
  27. Hi. I'm a student within the mechanical engineering dicipline. I'm currently working on a single span portal fram building with a crane frame. So far the snow actions and wind loadings are done. But it seems to stop. I'm not confident how to start off the design. I was thinking about making a FBD solving for member and reaction forces and from here decide the sections for the members and then designing the joint connetions finally. I would be thankful for any advices or useful documentation. Yours Sincerely

    Hallo. Eurocode has two methods for design of axially loaded piles (EN 1997-2 annex D.6 and D.7). These will not provide you directly with the adhesion factor alpha you're looking for, but may help you with the design. If you want to find the adhesion factor alpha refer to good literature for pile design. For now, I can tell you only that the factor does vary, usually from 0,25 upward, but it depends on many things, so again, refer to good literature. You may start with books from Tomlinson. Cheers
