Eng Tips Attic Lateral Design

Either way i think you should investigate the lateral load paths in this house.

Eng tips attic lateral design.

Lateral stability aspect ratio d b b d d b 2 no lateral support required b d 2 4 ends held in position b d 5 6 laterally restrain ends and at intervals along length of less than 8ft. How does a ridge beam prevent lateral pushout of home walls. Design wind speed up to 10 m height from mean ground level shall be considered constant. Where v z design wind speed at any height z in m s.

Mapped spectral response accelerations s s and s 1. Seismic importance factor i e and seismic use group. Structural engineering general discussion. Spectral response coefficients s ds and s d1.

And compression edge held in position with sheathing b d 6 7 laterally restrain ends both compression and tension sides. K 1 probability factor risk co efficient k 2 terrain height and structure height factor. They are legally backed by the engineering profession. The design wind speed v z is given by v z v b k 1 k 2 k 3.

K 3 topography factor. If these requirements. Loads govern the lateral design of the building. Several of the tooling and casting requirements of a part can be addressed at the design stage.

2attic loads may be included in the floor live load but a 10 psf attic load is typically used only to size ceiling joists adequately for access purposes. Eng tips engineering forums is an intelligent work forum community for engineering professionals of all disciplines. However if the attic is intended for storage the attic live load or some portion should also be considered for the design of other elements in the load path.
