Dear sir, In My attached fil,I am creating a deck slab to make my steel beams as a composite beams.But I notice deck slab somewhere missing the steel beams .some beams are not composite?Why it is happening?do I have to add that beams manually in stad…

Hi, I have a large STAAD model file for a linear analysis of a space frame. I have used the INACTIVE MEMBER/PERFORM ANALYSIS/CHANGE commands to sequence the framing as the loading is applied. When I run the analysis I get an error message stating…

Dear sir, In attached stad file. I am applying the dead load 2kn/m2 as floor load. 1.somewhere I am attaching two secondary beams with primary beams with the same node.is this load distributed all over the area same as 2kn/m2 or where I am having…

Hello, Is there any way that i can perform Fatigue analysis for steel member in STAAD.Pro? Thank you in advance

warehouse.zip wind calculation also in that folder.... try to fix this probem guys

Hello, I have done a beam analysis and the shear at the middle is excactly 0. When i use " SECTION 0.5 MEMB 1" the results are okay. That means in the output file "shear y" is 0 at position 0.5. But when i use SECTION command with 2 or 3 positions…

Dear sir, I am doing a design calculation for cat ladder using solid plates and round bar .But it is not giving me results with utilization ratio?how i can design it.Kindly suggest me method for these profile.stad file is attached. CAT LADDR.std

Dear sir, I designed a structure by using both method.in first method i deaigned it by composite beam method.and in second method i do it with composite deck.but by using composite beams giving lower utilization ratio than composite deck method.can…

I am analysing an RCC box girder for which some peculiar tapered sections have to be created. I created a tapered rectangular section in AutoCAD 2014. I used polyline to create the 2D and then extruded it to make it a solid 3D section. Now when I import…

Hi, I'm modelling a circular silo and assign incline supports and compression only(KFX) supports, but half of the tank support reaction results into X direction is Positive(+) and the other half support reactions into X direction is Negetive (-). Can…

I'm working in built-up column with four I sections. I'm getting some results and not sure the results are correct. Can someone please check the model is correct? Thank you. Built-Up column.STD

I have got my report, but there is no loading details like dead load, Wind loads and all... In report settings i have added Loadings, but its not showing.... Wt to do???? i want to see other load details. How to get that details?

Hello, I need your help on my design. Please have a look and suggest what is wrong in attached model. it's showing actual ratio is Inf. Stucture 5Deg.STD

I am designing an industrial shed. Can I enclose the shed all from the four sides up to the lowest purlin. I have analyzed this shed on staad.pro and its OK as per ASD design methodology under wind loads. I have heard that it is important to give gap…

I have calculated ratio for a member (Fa / FA + fbz / FCZ + fby / FCY); which is come 1.076 for member 11 but in staad pro it is 1.003 please let me know how to calculate this ratio. please have a look in attached PDF on page 2. PDF

Hello, I have one question for actual ratio and interaction ratio. here I am attaching two image for same member, when we see actual ratio in unity check for beam no 92 its something 1.278 and when we check this in member design then interaction ratio…

Hi, I have done a line model in staad pro as attached below.../ if I change the support 1 as 2 then reaction and moment vary why...? 3056.model.std

I start analytical model in STAAD Pro without defining any MATERIALS, and only define CONSTANTS. Then if I open the .STD file for adding some commands manually, and close it again, the program automatically add MATERIAL definition lines, and I get error…

Hi all, 1) Is there a way to set the ground level in STAAD Pro or is the y=0 level the permanent ground level? This is for the purpose of computing the seismic forces because, from what I know, distribution of the computed base shear per level of a structure…

Dear Frds, I have modeled a steel frame and design using EN 1993-1-1:2005. I have attached the model for your reference i that model correct or need to add any other steel design parameter?? I have attached the design report also in which member…

Hi all, When a member is subdivided into several beam member , each member should be manually assigned with actual effective length... This is because the default effective length is length of member(member in black box have only two member in…

Now a days railway and other industrial structures using trussless roofing or self supporting roofing system. In these types of roofing,the plain colour coated steel sheet is cut to required length and feed in to forming machine. The plain sheet after…

Hi, I want to modify the result tables; it divides the beam 5 increments to show stresses at each 5 point. Is there anyway to modify that increment that shows results. Thank you, Jeffrey

Dear all, I did the dynamic simulation of a particular foundation on staad pro that the model was working without any problem. I've then added some rigid links at the bottom of foundation which have been linked to one spring at the center of gravity…

When I try to "return to analytical modeling" from the physical modeller I get the following error: "Unrecognized Guid format." All I changed from the last time I updated the analytical model is some member releases. How can I resolve this error?
