@phamENG previously I have not done this kind of wall foundation, I need to check what are the others used as foundation/excavations if any one have done similar kind of things. Frankly I need some frequently used dimensions to get the idea that my design is following the industry standards.

For any single floor building (Only load bearing walls no RCC columns)approximately how much depth of excavation required from GL and what will be minimum continuous strip footings cross requirements which is below the brick wall throughout its periphery and what will be the reinforce...

I did not get you.

How are freeway bridges built? Any step by step explanation is there?

Thank you for your information. [smile] So concluding that pre loaded bolts (Bearing or pre-tension bolts or tension/shear interaction bolts) are different from slip critical bolts (Friction interaction bolts).

Is pre loaded bolts are slip critical bolts? Or we can refer pre loaded bolts as a TC or PT bolts. Please provide your opinions.

Any one has any opinion on this.

Usually Dead load need to be calculate based on concrete thickness on pan and other components. Mostly it will come nearby 50 psf and for Terrazzo or 4" thick concrete filled pans it will go up and can be consider 60 - 65 psf for staircases. You can refer NAAMM Manual 5th edition and AISC Design...

Hello Fellow Engineers, As per AISC we need to consider vertical seismic (EQ+Y) acceleration when spectral response acceleration parameter at short periods will be equal or exceed 0.125 So, Sds => 0.125 (First criteria) Please let me know if any other condition will be applicable here.

Hello fellow engineers, I am designing a fire safety door which I need to support with hangers from floor slab. Where I face difficulty to connect the hangers with floor deck. So I have used P1000T Unistrut with 1/2" Kwik washer for 1/2" dia. hangers. Hanger reaction force is 500lbs. Refer...

Hello masonrygeek, it is the Linton beam shown in snap-2, as an option to provide resistance for uplift instead of anchor rod direct embedded in masonry wall. I feel with Linton beam will be provide more resistance. Your response will be appreciated. Hello @steelnz2003 thanks for your...

Hello fellow engineers, Please get me a clear view on below clarification. As per IS codal(IS 1905) provision we should not add tensile stress on Masonry which contact with water. So in flood prone areas during high wind masonry structure will affect with tensile stress on roof and nearby...
