  • How to model sloping parapet walls in RAM Structural System

    Hello, I have a one-story building with sloping parapets on the exterior walls and flat parapets on an interior portion (see white colored parapets in image below). Currently, my model has the floor and the roof, with the roof having the deck and…
  • RCC Design of beam

    Hi, is there any way or how to add moments on Beam acting due to load on it.? Describing briefly, lets say there is an existing structure. Now there is a provision of new wall/ panel. so i want to check that " the base moment acting on that wall due…
  • How does RAM compute the transformed MOI for AISC's effective MOI?

    Hello, I am wondering how RAM Steel computes the I_{tr} for composite beams. For example, I have a composite beam with the following properties as computed by RAM: But by hand, I am computing I_{tr} = 941.86, slightly less than RAM. I am guessing…
  • Question on Modulus of Elasticity of concrete in STAAD

    Hello. How does STAAD compute the modulus of elasticity of concrete (default material properties)? The default values are: fcu is 27.58 MPa E is 21728 MPa Say I would like to use f'c = 27 MPa, what would be the corresponding E and fcu? I know…
  • Error:Exception[Access violation]Raised

    Hello,sir: When I run analysis in STAAD PRO it can't continue and the error come out as the picture attached below. This model is OK but after some beams added this error come out. And I have tried to add MEMORY 120 or adjust the NL xxx but this problem…

  • Coordinate system for reports in Structural Post Processing menu

    EARLIER Q: What coordinate system is used for the reports in the Structural Post Processing menu? REV 7.05 A: The reports in the Structural Post Processing menu are reported in the beam coordinate system. You can ask MOSES to tell you what this system…
  • Difference between hydrostatic and structural bending moments and shears

    Q: I have a rectangular barge modeled as a line of beams with a uniform load distribution. Why are the structural bending moments and shears not what I get from statics? REV 7.00 A: The difference is the way the loads are applied. The weight is divided…
  • *** FATAL ERROR: Nodes Are Not Connected to Rest” message

    Q: What does the message *** FATAL ERROR: Nodes Are Not Connected to Rest mean? REV 7.00 A: It means that you are trying to analyze at least two, independent structures. In MOSES the subset of the model you are trying to solve must be connected. This…
  • "*** WARNING: Fixing Zero On Diagonal Of Stiffness At *X.XXX" message

    Q: What does the message "*** WARNING: Fixing Zero On Diagonal Of Stiffness At *X.XXX" mean? REV 7.00 A: There is a zero on the diagonal of the stiffness matrix at the specified node, and MOSES is adding a large spring at that degree of freedom.
