I am creating a model of a building that is adjacent to an existing building on 2 sides, and exposed to wind on the other two sides, see snip below. There is an expansion joint between the buildings, so I am modeling the new building as a standalone structure…

Hi, My company usually only use one wind definition for wins area load and factor it for different wind cases. I have 3 wind definitions, and I am getting these messages in Editor. Is it a warning message? DEFINE WIND LOAD TYPE 1 NESC HEAVY INT…

Good day! How to solve this warning? I already set the range of application in the load cases details, still no avail to fix this one. Thanks.

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…

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…

Hello Does anyone have a code or a macro to generate wind loads automatically in STAAD using Eurocode 1991-1-4 for a long duopitch roof structure ? I only have the IS875 in the drop down options for 'Wind Load Generator'. I tried to apply the…

Good Morning Everyone, I am analyzing a conveyor support and housing, The structure is located on a pier thats why I added WL & EL. However, there is an error on analyzing the file. Please help me. The nodes are on the same level. Also, please…

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…

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…

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.

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…

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…

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…

0245.struc.STD 1) After applying floor diaphgram i am getting following warning *WARNING- ZERO STIFFNESS IN DIRECTION 2 AT JOINT 32 EQN.NO. 188 ***WARNING - INSTABILITY AT JOINT 980 DIRECTION = MY 2) Have i applied the moment release correctly…

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…

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…

I have an issue about wind load , when i have (bracing) on the side of whorehouse the area of wind load are dragging to corner of screen and when i delete the (Bracing) the wind are being OK as you see in the pictures it appears that lines are…

I'm using RAM SS to design a building where we have raised slabs modeled due to a bridge framing into the building. I'm wondering if there are any special requirements in order to have RAM use the main floor diaphragms to calculate the tributary heights…

Hello everyone, First of all, apologies if this was discussed before but i could not find the answer for this. I have a question about wind load calculations in MSTower software. I just started to use MSTower and try to understand its logic. It is…

Hello, Currently, I am using STAAD pro Connect edition's latest version. Following are question mainly targeting of RCC and Steel structure design in STAAD Pro and in other Bentley tools per Eurocode with German N ational Annex (NA). 1. Can…

Hi Engineers, I have modeled a truss structure , in that model wind load is not applied properly../ i have attached model below for reference.../ 01256.std

How to make Wind Load ignore Cross arm like this picture?

Hi, I am trying to use the automatic wind load generation tools in staad pro to distribute the wind loads to a large portal frame. I have tried a number of ways to distribute the loads. The only way I can get the one-way distribution that i would…

I have a model of a portal frame that is linked a to a revit model using structural synchronizer. The structure is a substructure, this section of the building is at 10deg to the main structure. Therefore my model does not align with the global axis.…
