Civil Engineering: How Buildings Stand
Discover how real structures carry weight, resist forces, and stay standing. Learn to calculate loads, select materials, read structural blueprints, and avoid catastrophic failures.
Like Duolingo, but for Civil Engineering: How Buildings Stand. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
25 levels across 4 sections, about 50 minutes end to end, roughly 10 days at five minutes a day. It moves through Tracing the Flow of Force; Foundations and Construction Materials; Loads, Stresses, and Sizing; and Plans, Models, and Site Realities. It starts from scratch.

Key ideas in Civil Engineering: How Buildings Stand
- A floor slab collects surface weight and transfers it horizontally to supporting beams
- Beams deliver weight into vertical columns, which channel it down to footings spreading the load into the soil
- Gravity loads must travel in an unbroken vertical chain from high elements down to the ground
- Dead load includes all fixed, permanent parts of the structure itself like slabs, walls, and framing
- Live load includes temporary, movable, or transient weight such as occupants, furniture, and vehicles
- Engineers must account for both when calculating total gravity force
- Wind and earthquakes push buildings sideways, creating lateral loads that cause rectangular frames to rack or twist
- Diagonal bracing, solid shear walls, or rigid moment connections convert sideways pushes into tension and compression forces
- Vertical gravity columns alone cannot prevent sideways racking without lateral bracing systems
- Every upper floor and roof load relies on a continuous vertical path directly down into a foundation
- Removing a load-bearing column interrupts the load path, forcing beams to carry unexpected point loads that can cause rapid structural failure
- Interrupting a load path requires installing a substantial new transfer beam or column to redirect forces safely to the ground
- Tributary area is the specific patch of floor extending halfway to every adjacent support that a column is responsible for carrying
- An interior column gathers load from halfway to its neighbors in all four directions, giving it the largest tributary area
- Perimeter and corner columns collect load from only two or three directions, carrying significantly smaller tributary areas
- Floor slabs act as continuous flat surfaces collecting dispersed live loads like people and furniture
