Hi, I'm studying the floor vibrations on a model that consisting of three floor A, B and C, despite floor A and C are symmetric, they show different ultimate acceleration because STAAD considers one of the girders only for calculating the results of…

I'm trying to model the attached floor system, and I need to make sure following points: 0- Can I draw the composite deck to cover all the floor area or do I have to draw it for every panel in the floor. because when I'm trying to cover the whole…

Hi there, I have some doubts modelling RC walls in the RAM Concept. Having the walls as shear wall which would restrain the slab improves the deflection in the slab, other properties are fixed near and compressible. I also have another opinion which…

Good Day, I have attempted the direct analysis method on a steel structure I have to design, however I have the following queries as it relates to the effect tension only members will have on the analysis (the structure has tension rods in the form…

Good day I have modeled a structural steel frame building and analyzed it using the direct analysis method, however I have received a few warnings and I would like to know the relevant of these as well as their potential effect on my analysis results…

Good day, I have used Staad to model a composite slab and design the beams supporting this slab. However, upon completing the steel design in staad the design results presented are very strange. All the members passed, however the results only presented…

Good Day, I have done a seismic analysis and noticed the following note: ***NOTE: SEISMIC LOAD IS ACTING AT CENTER OF MASS FOR RIGID DIAPHRAGM. TORSION FROM STATIC ECCENTRICITY (esi) IS INCLUDED IN ANALYSIS. DYNAMIC ECCENTRICITY APPLIED = DEC -…

Good Day, I have modeled a staircase in Staad using beam and plate elements, but I am unsure about the suitability of the model. My main issue I have relating to the model is whether or not the analysis results obtained for the columns are accurate…

Good Day, I have analyzed and designed a shear wall following the ACI code in Staad and would like to clarify some results.. The shear wall design has reported Edge reinforcement, however the length of this edge or boundary zone has not been reported…

Good Day Everyone, I wish to analyze and design an underground cistern (tank) using STAAD Pro. However, I would like some advice as it relates to the supporting conditions for the base plate. Based on my idealization I used plate meshes to form my surrounding…

I am modeling simply supported pedestrian bridge which have 2 architectural arch at both sides. My questions are :- 1-What are the possible ways to draw arch in Staad Pro?? 2- How to make Staad Pro understand that it's not structural element but…

Hi Everyone, I am trying to design a steel composite deck using staad and I have a few queries: 1. How can I obtain the analysis results for this composite decking? 2. Can staad design the composite deck, and if so, how can this done? Thanks…

Hi Everyone I have modeled a building and used the wind generation tool according to ASCE 2010 to get my wind loading. However, when I access the results in post processing, under the beams>graphs sub-tab, and select any column the Mz graph is not giving…

Hi Everyone, Is it possible to get accurate analysis results from a model containing both reinforced concrete frames and structural steel frames. I am currently modelling a structure that has a reinforced concrete ground floor and a structural steel…

Good Day fellow colleagues, I have tested two models to complete a shear wall design using staad pro. In one model I included only the shear walls, beams and columns and in the other model I included all of the above mentions elements plus the slab…

Hello, How do I model guy wires into my steel pole? Whenever I insert nodes to the steel pole.. The rendering of steel pole is not good. Also, did my placement of support is correct? Thank you for who will answer.. STAAD INPUT: STAAD SPACE START…

Dear sir, I am getting the warning as instability in the direction of Fz.Please help me solve this. I am not able to understand the instability problems.Please help me STAAD SPACE START JOB INFORMATION ENGINEER DATE 14-Jun-16 END JOB INFORMATION…

Hi there, I'm stuck with some warnings in my STAAD model. I've attached the STAAD file which is basically a simple SPACE model of steel frames supporting solar PV panels. The warnings are related to 'INSTABILITY' which I couldn't quiet figure…

In most of the software there is option for unique coloring to the beams/plates based on the user requirements, kindly advice if it is possible in staad, if not possible please consider this mail as feedback/request for the future up-dations in the s…

Slab Design 2 Deck Analysis 2.std Good Morning, I am designing grade beams (in the transverse direction) with a plate on top (acting as the deck). I have generated moving loads to go across the beams. When I look at the output files, the bending moments…

I am currently designing a deck slab, supported on grade beams (pile caps), on piles. I have created my beams, set the properties, and put a plate on top to act as the deck. My supports are the locations of the piles. I am having trouble obtaining the…

Dear Sir/Madam, I have designed a Frame using web tapered members in STAAD Pro. The frame weight shows the weight of different beams members used. For example, the frame is having a member whose dimensions are Web- 250 to 750 mm Web thickness…

I have two issues: -I tried to export .dxf from STAAD and saved that file, but when tying to open it with AutoCAD 2006/2015 nothing was shown on screen and even like nothing was exported. Do Ihave to select members or do some previous step before? - Is…

Dear bentley & friends, I had modeled the floor beams as composite and gave design parameter for Eurocode but design not performed and I had changed the code to BS and AISC, in this two codes composite design is done but not in eurocode. Why? How…
