Basically when we bought this house there was a small screen door on each side and all the posts were wrapped in aluminum, then the entire thing was wrapped in screen.

Upon taking off the aluminum we found the sides are just 2 2x4 nailed together with the screen wrapped im assuming for just some kind of framing for the screen doors and screening. Now at the end they are all 4x4s. The 2x4s on either side are not even secured to the concrete or line up on either side.

Without seeing under the roof do you think it's possible to remove a post or 2 on the sides to just open the room up? The end with the 4x4s are bolted into the concrete and there's a drop so those will all be staying.

All of them are wooden bars … like thin ones we get at construction sites and in homedepot … I’m using it for a personal project for creepers without the small corner bars … the entire structure is wobbling . So I decided to add two small wooden pieces

What to use to seal these cracks? Had drainage issues from clogged gutters /needing to regrade after we get these sealed as much as we can. Needed carbon fiber straps in basement from wall bowing we believe that what caused the Cracks

The video speaks for itself. Is this a ventilation issue caused by me not opening the door???

Photo for general reference not final design.

Designing a rack to carry pallets. All joints will be welded.
I plan to use either 4x4 x 0.120 or 3x3 x 0.250 Tube Steel.

The Base Plates .500 1’ x 1’ will be attached to a Concrete Floor with 4, 0.875 concrete studs each.

I need each pallet rack to hold 4200lbs per shelf.

Pallets will be static but replaced with a forklift periodically.

Obviously everything depends on the welds and whether my 2 Vertical Posts are able to handle the load.

Some things I’d like help with is how do I calculate my weight limitation on a design like this?
Should I use 5x5 instead for my vertical and make everything else 3x3 .250?

Hi all,

I’m at a bit of a loss here in regard to voids under my slab. I’ve recently purchased a house, the house is sitting on a cut and fill site on a sloped block. The retaining wall holding out fill section of the ground has failed and a lot of the ground has slowly decayed with it. To throw an extra spanner in the works the house had “chain drains” which were supposed to be connected to drain pits which would have been blocked for many years prior causing all water run off to go wherever it could. The house is supported by 23 piers that drive through the compacted fill and into solid ground, the house is solid and has no signs of serous structural damage and is holding itself up through the piers and beams, the drainage has been sorted now and the retaining wall is currently to being replaced, but all along the side of the house there are big voids and a hollow sound when you walk on some of the floors. I’ve had most underpinning and undermining slab jacking, resin filling etc company’s say that their services don’t cover what is required, which is a relief but also frustrating as I’m not sure what to do to fix the voids. Do I just fill them back full of soil and move on or should I fix this problem? Any help would be appreciated

House located in north east Melbourne

it’s 3 yr old house. not sure what is this crack type on first floor master bed room ceiling. it’s two story house in usa.

Looking a buying an investement.

1960s brick house with internal cement walls.

Cracking in quite a few places and large crack on front porch.

Mortar has been patched at front of house. Front sits on a slight slop. Most cracking is in the front half of house.

when tapping on repaired areas of cracks and some around the picture door frame it doesnt sound solid.

House sits on brick stumps. No large cracks spotted from outside. Floor boards seem prettu sold except a patch in the front room.

Just wondering if big or minor issue. And if the mud on the wall is a termite sign or just mud wasp getting into laundry.

Pretty keen on house as a first investement, its still above our price range but closet decent plsce to what we can afford.

Any insights appreciated.

This is an 3rd floor apartment in a 4 story building, year of built 2008/2009. The building is near to a big Lake, about 25 to 30m from the lake shore. Cracks are more noticeable the last 2 to 3 years. More in the Link: https://imgur.com/a/9VNIBce

Oklahoma City – condo with steel-framed balconies (looks like light steel joists + edge beam).
Temporary wood guardrail is not structural.
Seeing:
Rust/corrosion at steel members and connections
Likely long-term water intrusion

Questions:
Surface rust vs real section loss — how to tell in field?
When does this move to reinforcement/replacement?
Typical failure points to focus on?
Start with structural engineer or steel contractor?
Appreciate any quick insight before I bring someone out.

The cracking message in my wraparound porch.. I think I should be concerned about. How do I fix it?

Curious about this garage. 20x24, originally roof and walls were tied together by 2x4 rafter ties. TJI was added down the center with full length 2x12s on either side as web stiffeners. Both ends of the Tji are supported by 4x4 posts bearing weight, and 2x8s tied to the 2x12s with joist hangers 24” on center on either side as ceiling joists, and 4x4 posts mounted on top tied to the ridge beam. Collar ties and rafters ties added back. Finished with a drywall ceiling and fiberglass insulation. Will this hold up?
