    FEM Programming for inclined frame elements

    It's neither a in-box application nor in-house code, conversely a public-house :).It is published in book and I want it to improve a little further. :( Where the hell has gone these attachments this time. Something is ill-conditioned with this server. ok I upload them to different location...

    FEM Programming for inclined frame elements

    Thnx in advance, Sorry probably I couldn't expressed my problem well, but I think we are on right spot, there should be a transformation matrix to convert loc to global coordinates. Actually the program uses the trans. matrixes but just only with one angle and assumes that elements are...

    FEM Programming for inclined frame elements

    Don't know where has gone the second attachment so I post it again http://img37.imageshack.us/i/elements.png

    FEM Programming for inclined frame elements

    >wth is "the gamma variable" ? As I mentioned in my previous posts gamma is angle in degrees for orientation from local to global coordinates, the ,issue here is gamma is related just only one angle per element, that is, elements are assumed just only vertical or horizontal not for inclined...

    FEM Programming for inclined frame elements

    > a frame's a frame, inclined or not, no? Basically the frame is a frame, but how am I supposed to deal with the local axes orientations related to global axes? One way or the other I should provide the input for how the local to global orientation is. The book's approach is the gamma...

    FEM Programming for inclined frame elements

    hi all community members, I'm studying a book(Programming the Finite Element Method by Ian M. Smith and D. V. Griffiths) about fem for frame elements. But examples in that book especially for space frames are comprised only for orthogonal elements in 3D space. There are no implementation for...

    Couldn't find the equations in LRFD

    thanks in advance, >What steel specification are you using? The following references are for the 2005 ASD/LRFD specification, found in the 13th edition manual I'm using "Specification for Structural Steel Buildings, March 9, 2005" downloaded from aisc.org page don't know whih edition it's...

    Couldn't find the equations in LRFD

    hi all, I'm studying the Akbar R. Tamboli's LRFD book to better grasp concept of LRFD approach, downloaded the latest version of AISC LRFD specification from AISC site(Specification for Structural Steel Buildings). In the book there is the example of "Three Way Moment Connection" many checks...

    Initial Loading in Time History

    hi all, I would like to know what kind of approach I should take to define an initial loading/condition in time-history analyse(Ritz vector used). Generaly the ground acceleration at principal axes is been applied(in various examples and tutorials), depending on which direction you want to...

    What kind of checks needs to be peformed on shell cross section

    It may seem that I'm still dancing around the same issue. But Let's say that I have properly and adequately introduced all the requared loading(dead, live, e.quake, wind, modal combinations temperature etc..) conditions/combinations and take into account the previously design approach to...

    What kind of checks needs to be peformed on shell cross section

    Actullay I'm trying to design the wheat storage silo(approx. 6mt diam. 18mt tall). It doesn't have only the pressure, at least the analysis show that there are N,S,M in each face of shell. Actually there aren't codes in our country when it comes to the steel bin,silo design and analysis, so I...

    What kind of checks needs to be peformed on shell cross section

    Any idea ?

    What kind of checks needs to be peformed on shell cross section

    hi all, As the subject explicitly mean, if I know the stresses or forces acting on shell (s11, s22, s12, F11,f22, f12, m11, m12, m22, v13, v23 ) element (full shell behaviour) what type of checks do I need to perform to prove that shell element is full capable to carry bending, axial and shear...

    Construction Joints in Concrete

    hi YS, i completely agree with you about control and seperation(dilatation) joints. As long as they allow the free-movement(depends on DOF of joint) of super-structure due to the enviromental effects. What i intended actually to be answered is: For the concrete that we couldn't cast...
