Can a crane or telehandler lift the house's wall panels, and does anything but weight and wind limit it?
research/house-panellift
Can a crane or telehandler lift the house's wall panels? Weights of the eight house-offsite panels (343–559 lb open, 376–877 lb closed), best pick points and top-plate bending (4–12% of allowable with two picks): bending never limits the layout, weight and wind do. Hand-lifting needs 7–18 people; a 20 ft open panel swings 10° at about 12 mph. Stylised, every density and coefficient assumed.
What it found
Takes the eight wall panels of house-offsite and finds their weight (343–559 lb open, 376–877 lb closed; 3,753 and 5,031 lb for the shell), the best two pick points on each, and the top-plate bending at a 1.5 impact factor: 4–12% of the allowable stress, and plate bending alone would allow a solid panel of 60 ft with two picks (28 ft with one). Bending never limits the layout; the lift is a weight and wind problem. At the NIOSH 51 lb limit a panel needs 7–18 people, so hand-lifting is out, and a 20 ft open panel hung broad face to the wind swings 10° at about 12 mph (15 mph closed). Stylised: densities, glazing weight, impact and drag are assumed, the lift is a rigid-body estimate, and the sheathing is ignored.

- How much lumber, labour and heat does advanced framing save in a house's exterior walls, and does it still carry the roof?How much does advanced (OVE) framing save in a house's exterior walls? Stylised 28 × 40 ft house: 42% less wall lumber and 27% fewer pieces than conventional 2x6, whole-wall R 16.2 to 18.6, studs at 39% of capacity under 30 psf snow; the lumber is worth only $450–900 a house, so labour carries the case. Not a code check. First project of track 12.
- How far can a 2x joist, rafter, header or beam span, and which check limits it?How far can a 2x joist, rafter, header or beam span? Open NDS sizing tool, no table copied: 2x10 SPF floor joists at 16 in span 15 ft 3 in, bending governs most floors and snow rafters, deflection most ceilings; deepest joist at 24 in uses 20–50% less lumber (vibration unchecked). Not validated against published tables. Milestone 2 of track 12.
- Does a floor-vibration frequency limit erase the lumber saved by deep, widely spaced joists?Does a floor-vibration frequency limit erase the lumber saved by deep, widely spaced joists? Beam-theory first-mode frequency on the
house-spanschecks: limits up to 10 Hz change nothing, 12 Hz shortens a 2x10 at 16 in from 15 ft 3 in to 13 ft 11 in, 15 Hz moves the least-lumber 12 ft joist from 2x10 to 2x12. Joist alone, limit is a policy knob. Stylised.

Gamma-method partial-composite stiffness on
house-vibration: at a 15 Hz limit a 2x10 at 16 in grows from 12 ft 6 in to 13 ft 2 in–14 ft 6 in, depending on two assumed inputs (connection efficiency and panel modulus). Stylised. - Does a joist lapped over a middle support span farther than a simple-span joist?Does a joist lapped over a middle support span farther than a simple span? FE beam with pattern loading and NDS checks: two-span peak moment equals a simple span's, so bending-governed floors and snow rafters gain nothing; deflection-governed ceiling joists gain up to 18.5%; 1.5 in bearing on the middle support cuts a 2x10 floor joist to 11 ft 4 in. Not validated against published tables. Follow-up to
house-spans.
