• shear reinforcement is staad pro

    i am designing a beam from IS 456 in connect edition 1st time before SS4 is used so it is observed that spacing of the Shear Stirrups is more then 300 in old version it is limited to 300 currently I am using update 12 of the Connect Edition please look…

  • RAM Concept Shear Reinforcement Section Design

    Hi, I'm trying to get a deeper understanding of why RAM Concept is showing my shear requirement as being larger than the same beam I have modelled in RAPT to verify. RAPT does not require any additional shear reinforcement. I have checked the shear…

  • Error? in kv calculation in RAM Connection

    Hi everyone. I was calculating a joint in RAM Connection, and notice that, from my POV, is a mistake in definition of a and h values for calculation of kv. In this picture you can see a beam seated on a column, with following dimensions: …

  • SHEAR Failure of RAFT in STAAD PRO - need asap help

    Hi, I am modelling a substructure in STAAD Pro and after application of loads when i ran analysis i got my raft failed in shear. my allowable shear is 0.675 KPa and the actual shear stress is 1.5 KPa, i have ignored the plates under the columns and even…

  • Shear in PT beams when Design column strip for Column + Middle strip resultants is checked

    Hi there, I'm designing a parking PT slab with PT beams in a corner panel where we have higher loads. I noticed that the amount of shear reinforcement in the beams running parallel to the distributed tendon (longitude direction) increases exponentially…

  • I am attaching a simple g+2 building which I have analysed in Staad. Have few queries about the same.

    I have given the clear cover to be 25mm in beams and 40mm for columns as per Indian Code. Further, I can see from the design output I can see from the design report that the clear cover is 35mm even though I have given 25mm in the input for the beams…

  • RAM Beam Shear Reinforcement Output in Slab Span Direction

    Hi, I've come across this particular issue a number of times but have never had RAM specify this much shear reinforcement before - see snapshots below. This is a one-way slab and band beam system so wouldn't be expecting shear ties in the beam like…

  • 1 way shear effective depth calculation

    I have an existing two-way slab that I am trying to analyze. At locations of negative bending, the effective depth for one way shear calculations is much smaller than I'm calculating it to be by hand. Based on the value that the audit is showing, it…

  • Como obtener periodo de vibración para cada dirección X, Y y Z

    Saludos a todos, en México se ha modificado el análisis por sismo, me piden realizar la comprobación del cortante basal en cada dirección ortogonal, mínimo en 2 direcciones (X y Z), así como la verificación del estado límite de servicio para sismos frecuentes…

  • RAM Connection Elastic Weld Demand

    I am using RAM Connection for a base plate. The base plate has both uplift and shear concurrently. I was looking to see how the interaction of tension and shear was done on the weld and cannot figure out what RAM is doing to calculate the demand. …

  • No results from cut by a plane method

    Hello, I attach my Staad model for your attention. I am wondering why the plane I have cut does not give any values for Fx, Fy and Fxy? Also I cannot obtain a number of the outputs from the cutting plane such as global moment etc? I am looking…

  • RE: MAT FOUNDATION (Overturning)

    I checked with the STAAD Foundation Select Series 4 (05.03.00.34) and confirm that the horizontal shears were considered to be at the base of the mat and so no overturning moments were calculated. When one includes the pedestal, the moment is calculated…

  • RE: Story shear at each floor

    You may use the SET PRINT 17 command in the input command file as shown next The analysis output file would then list the shears at each story on a mode by mode basis. You need to manually combine (SRSS) the shear values for each mode to arrive at…

  • RE: Extract different stresses from staad post processing menu

    You are correct. A +ve value of Bend-Z represents bending compression and -ve value represents bending tension. The Axial column in the same table represents both axial tension/compression. A positive value represents compression and negative value…

  • RE: RAM Frame Story Shear with Multiple Diaphragms

    When the diaphragm is pseudo-flexible, the location of the graphic for the diaphragm shear is largely irrelevant. This wiki indicates that it's somewhere near the geometric center. If you look at the building story shear report, you'll see 4 lines in…

  • Does STAAD show maximum shear & moments in the DECK or in the GIRDERS?

    We have modeled a two-span continuous bridge (50' spans), 6 girders in the cross section (60' bridge width). We are loading with truck & tandem loadings per AASHTO bridge design specifications. When analyzing for maximum positive & negative shears and…

  • RE: Bent Plates in RAM Connection

    I think the situation here is that AISC 360-10, Table 10-9 is used in the case of a single plate connection only. We opted to only implement this for shear tabs since it's within that specific section of Chapter 10, but it would be a good question for…

  • RE: Ram Concept- Shear Reinforcement

    If you look closely at the section audit for a section from each case and compare them side by side it's a little easier to tell what is most significant. Below is a table of just a few lines from the audit to help you, ultimately is a small change in…

  • RE: Vertical Shear Contour Plot in RAM Concept

    I would normally recommend plotting Slab - Shear - (Mid depth) Max (and Min) for this, though you will get a warning like this for any Rule Set: --------------------------- Slab Plot Accuracy --------------------------- The selected slab plot may…

  • SHEAR in RAM

    Dear RAM Concept crew, I would like to know how the shear design is done (not punching shear). I am using Eurocode 2. My question is: where is it checking the shear capacity? According to the EC it should be done at “d” distance from the edge of the…

  • STAAD shear calculation error for AISC 360-10

    Hi All, I have noticed that STAAD incorrectly calculates the shear capacity for a member. Specifically, it uses a VERY large shear area (overstated by a factor of 2!). Here is the output for an Australian 250UC72.9: INTERMEDIATE: Aw: Cv: Kv: h/tw: Vn…

  • User Shear Bars in RAM Concept

    I'm (still) working on analyzing my existing waffle slab. I've worked out a lot of the kinks, but the user shear bars are still throwing me for a loop. I assign user shear bars adjacent to the column drop cap like so: The result once they get…

  • RE: Waffle Slab in RAM Concept

    I think the Concept analysis is limited to a single core which might account for the limited CPU resources it claims. Using the 64 bit version and he Pardiso solver are good ideas. The other things I can think of to possibly speed things up are to: …
