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...
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...
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...
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...
Hi all,
Is there any requirements for construction joints when designing water towers, shear-walls, retaining walls, slabs etc? The requirements that i have seen in ACI/UBC-97 leads me to the "shear-friction" calculation. Just taking into account the "shear-friction" calculation may we create...
hi all,
Solving beams reinforcement with etabs and safe gives me two different reinforcement area. if I export the drawing to the safe (with same load-case) and run the analysis the beam reinforcements becomes less or more from etabs but never the exact value which has been found in etabs...
hi all,
yesterday I have encountered a very strange outputs of etabs. I was analysing single storey structure, load case was only with gravity uniform loads on floors (rigid diaphragm), everything went so normal run the analysis and after that i run the design/check( concrete frame,EuroCode-2)...
Hi all,
I want to design 4 storey structure comprised of RC Column-Beam where some part of floor slabs will be used as hollow core slabs (to serve as sound-isolator).
The system for such a stucture could be easily created even using template, but the problem arises when determining how should...
Hi,
Is there any limitation for the dilatation in the codes EuroCode or American? For example, where building length in one direction exceeds X meters should be seperated in two buildings.
Best Regards,
hi,
Does anyone can tell me, how am I supposed to calculate the deflections of compressed elements which have buckling as well. It makes me think that this deflection should be function of X which is ranging from 0 to element length(such as d(x) = X^3+2X^2+....)
Thnx,
Hi,
I need an algorithm which is capable to calculate the Steel bars in a given concrete cross-section where moment, shear-force, normal force and cross-section properties is known.
Can you direct me to sites or source - code in any language will be appreciated much more .
