Hello, Can anyone help me to know the age of the lighting pole shown in the attachment? I found this plate which seems has information about the manufacturer. I guess it is a production of 1945 but not sure. A full-size picture is attached. Thanks...

Hello, New update. Yes, I just discovered the let-in bracing. Also, have found a portion of the design drawings which has a general note saying "lit-in bracing to be provided at all house corners". The proposed window will be located at the same location as the lit-in [sadeyes]

Great posts, Thanks all. @dauwerda actually there are no lit-in breacing found nor hold-down in the existing structure. The external sheathing is fiber cement panels, a nearby house with the same design has a horizontal board sheathing. it seems it is relaying to the gypsum.

@dik Would you please elaborate? If you asking about the weather, it is hot generally, in winter 60F and in summer it is 113F, and it is high humidity area. The building paper is added neat to external face (out side) of the wall. @r13 That would take the gravity load only. How can I improve...

Hello all, Is it OK to add a steel frame around a new window to provide vertical and horizontal stability in a townhouse made of wood? It might be a simple question but I have been hired recently for a renovation department dealing with a wooden house compound built in 1981 in Saudi Arabia as...

Thanks a lot wannabeSE I really appreciate your help, I just wanna understand the complete meaning. 1-I am confused about how I can terminate the test while removing the load ?!!!! I thought termination might happen if I am loading the structure, if I reach to critical situation (near to...

Dear all After I read "Periodic unloading, after the onset of inelastic behavior, will help the engineer of record determine when to terminate the test to avoid excessive permanent deformation or catastrophic failure." AISC 360-16 PAGE 16.1-551 I really think "Periodic unloading" referring to...

Dear all, please help me to understand the following: What does " Periodic unloading " means? does it mean loading the structural system? or removing the load from the structural system ? here is the context FROM A360-16, Determination of Load Rating by Testing, Page 16.1-235. " Periodic...

Warhamer, Thank you very much for sharing your understanding. When the code start saying "including protection .... etc" I thought the code referring to F-1, H, M, S-1.

Please help me to understand this footnote b in table 601. "Except in Group F-1, H, M and S-1 occupancies, fire protection of structural members shall not be required, including protection of roof framing and decking where every part of the roof construction is 20 feet or more above any floor...

Dear Ron thank you very much for your comments. I will recheck my calculation.However, the covering material is perforated, is there any exception in code to reduce such load in such case? Thx

Yes, therefor I am considering 10 psf downward case and upward case. the covering material is perforated. considering 10 psf seems to me very conservative,I am wanderings if there some exceptions in code that allow me to go below 10 psf.

I am using ASCE07-05 where the min wind load is 10 psf as per 10.1.4.1. and i'm using section 6.5.13. Actually I am not sure if my structure can be considered as building or not! in the link below u may find something similar to what I am designing...

We are designing a cantilevered car shade canopies to cover 18ft X 40 ft, but we end up using: 3 steel post 78.7X78.7x 0.4 in . 3 isolated footing (width 40 in) (80 in length) (30 in depth) it seems huge! right? we considered minimum wind pressure as 10 psf. is there any exception in the...

Thx a lot CELinOttawa. I really appreciate your advice.

Hello, Please I need help. I would like to design a stadium by wood and i need to know the specified strength. The available type of wood is ( Okoume from Gabon) scientific name Aucoumea klaineana.I don't have any more structural data about it. I am using the Canadian wood design handbook and...
