I'm using STAAD pro connect in one of our project. I observed that the utility ratios are different while checking with AISC 2010 & AISC 2016. Using AISC 2010 it gives more convincing allowable limits & utility ratios. if we check with AISC 20016 , with same file it gives errors in the output results.

Our client is asking to do the check with AISC 2016.

Is it possible in RAM connection to design connection made with pin?

Regards,

I Ran the model two times. one time by using HRS and another round by using BUS but I got the bending moment doubled at the BUS. pls advice about that.

Another surprise in STAAD Connect !

It’s about the deflection check. We have observed that output results for deflection checks are different between AISC 360-10 & AISC 360-16.

Whereas different in codes should not have any impact over the deflection checks.

AISC 360-10 results are more convincing , whereas AISC 360-16 results are seems to be with errors.

How can I find overall floor area with RAM DA in VBA(total area within all slab edge polygons)? I don't want to subtract the openings/penetrations. I based my code off of the RAM Material Takeoff spreadsheet found on these forums but it is double counting overlapping decks and subtracting opening areas.

Hello Community,

I have to design an H column with cover plate welded on flanges from inside?

Is this possible with STAAD, as per my info we can design cover plates welded to outside of I / H beam flanges.

Also this design is not supported as per by eurocode 3, so I am trying to judge its adequacy based on the beam stress results available in postprocessing.

Please refer below screenshot showing the beam stresses for an H column with cover plates welded on flanges from outside. It can be observed that the width of cover plate is less than the column width.

My concern is in stress table results, STAAD shows only stresses in H section corner (corner 1, 2, 3 & 4). Out of this max is 175.448 N/mm2. Whereas legend shows stress value upto 219.558 N/mm2. So can we consider the max value shown in the legend (219.558 N/mm2) as the max stress in the H section? Or where we can refer or get plot of stresses occurring in the cover plates?

Last question, if max stress in H section is less than the yield strength, can we conclude that we have satisfied the elastic criteria of Eurocode Eq. no. 6.1?

Regards,

Vishal

Good day!

I am using the command "Pdelta analysis print statics check". But whenever I click the save button in the GUI, the word "smalldelta" would appear. Now, it becomes "Pdelta analysis smalldelta print statics check".

Do you encounter the same problem?

Thanks.

I have a stair that I'm concerned may be susceptible to vibrational issues. I've often used RAM Elements to model a variety of stair configurations under gravity loads and ELF seismic loading, but can it also be used to check for vibration? Most of the information I'm finding online references using SAP to find the natural frequency for use in the AISC DG11 procedures, but DG11 also says that "several commercially available programs provide convenient features for computing the FRF magnitude". I know Elements can determine mode shapes via eigenvalue analysis, but what about the natural frequency? Any guidance on feasibility and/or ways to translate the procedures in the design guide to comparable inputs in Elements would be much appreciated. For instance, the amount of frictional damping on a stair plays a big role, and there's a damping input in the Earthquake Acceleration tab, but can any of the dynamic analysis functions for seismic loads be used for human-induced vibration, or would that not be applicable Thanks!

Hello, 

We have noticed recently that when importing a revit model into ram, it appears to detect some mass not associated with any diaphragms. I will note that typically, only the gridlines and levels are imported (i.e. no framing nor floors or roofs are imported). Can anyone help or give some guidance into what the additional mass may be? Keep in mind that whenever we have started a RAM from scratch, this message does not appear which has lead us to believe its an issue with importing a revit model. 

Thanks in advance!

Hello,

Firstly, thanks to all of you reading this.

I tried to understand what they(number of iteration, converge) do of P-delta analysis.

As per the help of STAAD(C:\Program Files\Bentley\Engineering\STAAD.Pro CONNECT Edition\Help\std_dls_P-Delta_Analysis.html)

       - "Number of iteration"  make perform analysis for the specified number of iteation whether or not converges.

       - "Converge" make perform analsysis for the speicfied number of iteration. But if the convergence made, then the analysis will be stoped.

I thought that there should be no difference if there is no difference of numbers.

As you could find out the attached files, the only difference of command is that usage of  "converge" or "number of iteration".

The numbers are same "3". and the they both did 3 times iteration.

So, I assume that the results will be same.

However the some results are different as follows:

1. Support reaction at Node 1.

  1) Iteration  : Fx=-2 kN

  2) Converge : Fx=-7.712 kN

( It is obvious that, the "converge" makes the moment equlibrium of support reaction from the second order moment(77.12kN-m) )

2. All Relative Displacement at 5m height of Beam 1

  1) Iteration : y = 282.148 mm

  2) Converge : y= 75.106 mm

(I could not find out what this means)

3. Node Displacement at Node 2

1) Iteration : x = 1504.790 mm

    (if, this function do not care about convergence, it shoud be 390.24mm = PL^3 / 3EI = 2.0 kN  *  10m^3/ (3*2.05*10^8kN/m^2  *  8.33*10^-6m^4) )

2) Converge : x = 1504.790 mm

   (From simple manual calculation - 1504.790mm = PL^3 / 3EI = 7.71 kN*10m^3/ (3*2.05*10^8kN/m^2*8.33*10^-6m^4)

As you could see above mention, not like the STAAD help explanation,

Not only the "convergence check" is added by the "converge function".

However there are no "detailed explanation" of them. 

To sum up, Could anyone kindly tell me

  1) What "number of iteration" and "converge" are ?

  2) What "number of iteration" and "converge" do differently ?

Hello,

I have a question about the IFACT value which should be used when compiling my Tower file. My structure is a fully triangulated structure with a majority of the connections being 2-3 bolts.

I have noticed that when I decrease the IFACT value for 1.0 to 0.5-0.1 that the stresses on the members decrease. I am just curious if I am able to decrease the IFACT value for my tower?

Thanks

Hello

I am using STAAD.Pro v8i SS6 v.20.07.11.90. 

I noticed that that load combination always reset every time I selected Ranges to be considered in Other Tab.. Is this normal? or a bug? 

Thanks

When i will perform dynamic anaysis after assign property reduction factor than we got the error like this.

*ERROR* STAR FILE MGR. ERROR NO.   6 DETECTED BY LIBREAD            THIS ERROR MAY HAVE BEEN CAUSED BY INPUT DATA ERRORS OR PROGRAM LOGIC ERRORS.     *** ERRORS IN SOLVER ***

what we need to do to eliminate this error

STAAD Foundation Advance file won't reopen after exiting. When I create a STAAD Foundation Advance file it seems to be working fine at first but once I close the file and try to retrieve it again the file won't open and STAAD Foundation Advanced just exits out. How do you fix this?

Dear,

Can you give some more detailed explanation / figures if posible to explain each of the options on the snap below:

Thank you.

Regards,

On two projects now, when running lateral design in the frame module, the software is using the calculated Cs value even when maximum Cs controls. Some relevant information:

Code - ASCE 7-16 

Sd1 = 0.287

Sds = 0.837

TL = 6 sec

Ts = 0.34 sec

T = 0.695 sec (approximate T)

R = 8

I = 1.25

Cs calculated = 0.13

Cs max = 0.065 * 1.5 = 0.0975 (Per 11.4.8 exception 2, Cs max is to be multiplied by 1.5 when TL > T > 1.5Ts)
