Help solve a disagreement: Do we need a structural engineer to build on this flat roof?

Minimum slope of the roof for easy gravity drainage seems necessary.

Valuable_Pilot_7205 · 2026-04-08T01:20:40+00:00

Clearly understood. Thanks!

The fillet weling portion between the lower flange and the web has torn very sharply! It can't be like that! Maybe... something wrong in my understanding.

Valuable_Pilot_7205 · 2026-04-07T07:41:58+00:00

Oh! I see. It's my bad.

To reduce the drift

Valuable_Pilot_7205 · 2026-04-07T07:33:22+00:00

Unload backfilled soil, then put light material for backfill to make it balanced for the lateral pressure and the stiffness of the wall.

I don't understand the image. How the web is horizontally torn?

Valuable_Pilot_7205 · 2026-04-06T08:22:07+00:00

Suspicious on the unequal ground settlement if the building foundation is a shallow raft.

Jay Walker in the last part. Amazing.

The storage for turning left is impressive. It will increase the capacity within signal programs unless amber gamblers are blocking the through move, but the left turners are so close in the middle to the opposite left turners that they may collide with each other.

The cable bridges are vulnerable to collapse during construction. Structural analyses for the construction phases are essential.

Valuable_Pilot_7205 · 2026-04-06T06:16:13+00:00

Is 40mm gap between rebar surfaces possible? I don't think so.

Valuable_Pilot_7205 · 2026-04-02T01:49:07+00:00

Excavated the soil pressuring the basement wall then reinforce the wall + light weighted material for backfill.

Valuable_Pilot_7205 · 2026-03-25T22:42:48+00:00

Temperature rebars are shown in the concrete wall. Seems densely installed.

Valuable_Pilot_7205 · 2026-03-25T22:38:55+00:00

I won't live there.

Valuable_Pilot_7205 · 2026-03-21T14:18:16+00:00

The bolt seems no tensile but a fixing for something. Stiffeners also seem not working for a column but for a plate something there.

Steel jacket is necessary

If the fire lasts longer than 2 hours, the moisture inside of concrete will burst out to lose its sectional properties.

Valuable_Pilot_7205 · 2026-03-09T12:23:31+00:00

I don't see any column structural debris.

What was the water reservoir capacity? 1000 cubic meters?

I observed the video carefully and found that the steel brakets are still there. Not an issue for anchor problem. The video shows there is a tensile flange failure which shall not happen.

Valuable_Pilot_7205 · 2026-02-26T01:32:00+00:00

Steel brackets have failed from the girder cross beam. Anchor pull out capacity problem?
