  • Wind Load on Tapered Section -reg.

    Dear Colleagues, current version : STAAD.Pro CONNECT Edition - Version 22.12.00.142 there was a situation where we had to find out the lateral forces due to wind on a light pole (tapered profile) and provide suitable support for the same. Wind was…

  • STAAD Wind Load Generator

    Regarding wind load generator in STAAD Pro V 22.06.00.138 My structure is simply a box structure but when using wind load generator applied to a group, the wind load generated in +X and -X as well as +Z and -Z have a discrepancy. It seems that loads…

  • ASCE 7 Generated Wind Loads in STAAD

    I am trying to check some STAAD models containing ASCE 7 generated wind loads. The details of these wind loadings are proving difficult to verify. If I use STAAD to open the .STD files I was sent, and go into the ASCE 7 wind load dialog box, it appears…

  • Modelling Existing Building - Excessive Horizontal Node Displacement where Column meets Truss

    Hello, I am modelling an existing building, which has a number of columns which connect to the bottom of trusses at approximately midspan. These Columns are at the building face where the wind will act on them. In all load cases where I have generated…

  • Why don't we have wind loads incorporated into Staad Pro as per IS Code?

    Even in Staad CE Wind loads are still generated using ASCE code. Also, a number of videos are floating around on youtube explained by people who are not at all subject matter experts.

  • Wind Projected Area on Angular Members

    Hi, I am modelling an open structure with angular sections as the vertical members (Telco tower). However I found that the wind forces on the angles are a bit large. So I did a test model to compare a tube 100x100mm and an equal angle 100x100mm, applied…

  • Modeling Slopped Roofs and Impacts on Wind Design

    Lately I've been running into issues with my lateral analysis on a large, square steel framed building. The roof is an 1-1/2" metal deck that slopes in one direction and drops 10' over the length of the building, which I've modeled as a semirigid diaphragm…

  • automatic generation of wind load

    . The automatic generation of wind load should be made available to Indian code also apart from American code.It will save lot of time in analysis and manual calculation. REGARDS, ATUL

  • Can a metallic sheeting replace the bracings to resist the lateral forces - seismic forces and wind forces, to add stability of the structure?

    I have a slender structure, 5 m x 2.4 m of height 18 m. I wanted to replace the lateral bracings from level 6 m and above with the metallic sheeting, 6mm or more. I have added the plates of thickness 6mm to simulate the sheeting and by adding intermediate…

  • Negative Load Case vs Negative Load Combination

    Dear Colleagues, Say if I have to apply wind on all the four sides (+x / +z / -x / -z) of an irregular structure/geometry, is it okay to consider only 2 positive cases (+x / +z) as Basic Load Case and generate 4 load combinations with 2 positive and…

  • screenwall at roof level

    I have a relatively tall screen wall at the roof level - about 20ft tall - around a mechanical area. The structure is kicked back into the roof diaphragm. What is the best way to model it so that RAM Frame accounts for its wind surface area? The footprint…
