Firstly, there are no hard definitions. Mid-rise: Between 3–10 stories. A lot of jurisdictions place the lower end at 6+ stories as most buildings can no longer be constructed primarily of wood. High-rise: Usually 7 or more stories. A lot of jurisdictions place the lower end at 10+ stories. This is largely attributed to Chicago’s …

Think of the ocean or any other large body of water. There are a lot of things going on. Hot spots, different densities, plumbs rising and falling within the body of water. Now, let’s put a large comparably thin material floating on top. Think of ice sheets in the arctic or antarctic. Ice sheets can …
Ian Marr·June 24, 2020Architect At no point am I aware of the length defining either. In the human scale, a tunnel goes through something and a bridge crosses over something. In the quantum scale, a tunnel is a passage through a time-space medium while a bridge tends to be connection between two separate things. But, …
Most foundations are going to be shallow foundations as they are almost always the easiest and cheapest solution. Bearing capacity is usually the governing issue for this. If you exceed, or come close to, your bearing capacity you would typically move to a deep foundation solution. There are other cases which involve special conditions in …

32″ is correct. But in many jurisdictions, the door slab counts against the opening. Again, this why 36″ opening are universally taken as the accessible door width.
Stanchion – Literally means an upright element. Some industries call posts or bollards that have tied loads on them stanchions. Post – Vertical load-bearing element. Larger or thicker versions tend to be called columns. Truss – A beam or similar, roughly horizontal, element composed of a number of sub-elements. Think of a beam with most …

No applied forces, including no self-weight. then the bending moment diagram and the shear diagram are a straight line. This is because no forces have been applied to the beam.
The Three Gorges Dam is a gravity dam, so it would tend towards more earthquake-resistant than most comparable objects. A gravity dam is a type of structure that doesn’t rely on the strength of the materials to resist the forces of reservoir and earthquakes but rather is built to weigh so much that these forces …
Technically, yes. Practically, there are far better choices. Let’s assume you are talking about tile grout. Its job is to bond to ceramics or stone and provide a strong wear surface. We really use a wide array of different materials that we call grout for this job, but as long as they do the two …

If you consider your single story home on the ground safe; then yes. The problems you encounter in tall buildings are different more so than greater. you should be pleased to know that a great deal more research, engineering, and skill in building tall buildings than goes into building a single story home. And yet, …
