Eng tips attic lateral design.

Either way i think you should investigate the lateral load paths in this house. Design wind speed up to 10 m height from mean ground level shall be considered constant. And compression edge held in position with sheathing b d 6 7 laterally restrain ends both compression and tension sides. 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. If these requirements. Structural engineering general discussion. K 3 topography factor.

The design wind speed v z is given by v z v b k 1 k 2 k 3. If the drawings say it s a shear wall and you say it s okay to remove it you now own the lateral load resistance capabilities of the structure. Design codes in general design codes are issued by a professional organization interested in insuring safety and standards. They are legally backed by the engineering profession.

Where v z design wind speed at any height z in m s. Spectral response coefficients s ds and s d1. How does a ridge beam prevent lateral pushout of home walls. 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.

Seismic importance factor i e and seismic use group. Several of the tooling and casting requirements of a part can be addressed at the design stage. K 1 probability factor risk co efficient k 2 terrain height and structure height factor.
