Hi,
Is there a proven standard solution for placing a bolted steel silo over concrete columns, considering seismic?
I was asked to evaluate an alternative to the steel braced frames, with rc columns, so seismic is reduced (replacing steel braced frames with rc moment frames, or possibly...
Hi all,
What's a good, updated book/resource/supplier-website to learn about earthworks and heavy equipment?
I'm exploring questions like how to select machinery, improve efficiency on loading material and moving it around, new technologies to do things faster, surveying tips, etc. A resource...
No possibility of external service. Its in the middle of the desert. Operation need to be internalized.
No customers to scare away, its for cleaning trucks for a small earthworks/mining contractor. No neighbours around 1 km.
It appears reclaiming water is tricky as i'm starting to notice...
Hello Bimr,
This will be a self service water spray with a pressure washer.
Climate is desertic, its in the middle of a desert.
There is no sewage, treated water needs to be drained or reused.
Want to recycle because the climate and to not use too much water, so we don't feel bad.
Yes...
Hello,
I'm looking for resources/books/info on how to treat and recycle water that has been used to wash vehicles (mostly plain dirt with some minerals). We are talking about a Grease trap plus maybe some Coalescing Filtration, so water can be reused for washing (not potable). Maybe also...
Sorry, attached sketches. Footing is 10 m wide, and stepped (0.8 m + 0.8 m). Seismic is controlling the weight of the footing (impulsive mass is big, is is a water tank). Axial loads are 153 tonf compressive, base plate is 60cm x 40 cm, and 78 tonf uplift taken by 6 1+1/2 inch A36 bolts, with an...
Is there any particular consideration on having an axially loaded steel column (compression and tension) placed directly over a deep footing (1.6 m deep)? without either a pedestal or pedestal rebar inside the footing (embedded pedestal)? Appart from punching shear, is there any other...
1. Lack of a structural base from architects. Specialization has brought too many problems. I think it would be better if we all where architects with an specialization (structural, mep, etc.)
2. Communication and coordination.
3. Lack of intuition, too much reliance on software, lack of...
It works in that situation but in this case the slab goes over the wall so it wouldn't work I think.
An UPE beam with shear connectors might do it, see attached, but would it be difficult to build?
Regards...
Spacing between frames is about 5 m.
No it is not an existing wall, but the likely constructive procedure the contractor will do is to build the retaining wall first and then the steel structure will be placed ( i would do that). The soil has good cohesion and can stand by itself during...
What would be the most appropriate way to connect a cantilever retaining wall to a composite deck slab of the interior steel building, of a semi buried house? So it works as simply supported. The composite deck passes over the wall. Can't find any similar detail anywhere that addresses both...
I can't have direct contact with EOR.
I do have a sketch where lateral system appears to be fixed base (is this even possible? I would assume rotational stiffness is difficult to achieve) plus moment connection at the joints.
Project is in Peru...
I'm on a small project where fabrication and erection tolerances where not honored, which means that bolt holes for purlins and girts need to be made for each span. I wish to change the detail and weld the splice with appropriate care and technique (thickness is 1.6 mm). I have not seen a welded...
Sorry for not being clear.
This is a portal frame building with metal cladding and roof, extremely regular. typology is like the attached.
Environment is not corrosive at all.
Most of this buildings here are made with steel + fire protection. This building could perfectly be a Butler's or...
Hi
I'm involved in a 4000 m2 warehouse project (50 m width with a intermediate column, 80 m long, 9 m height to eaves) and a contractor made an offer (turnkey) to do it with precast concrete columns, beams and purlins. The offer is sort of competitive (its more expensive than steel but does not...
