Eng Tips Attic Lateral Design

Design wind speed up to 10 m height from mean ground level shall be considered constant.

Eng tips attic lateral design.

K 1 probability factor risk co efficient k 2 terrain height and structure height factor. Design codes in general design codes are issued by a professional organization interested in insuring safety and standards. Where v z design wind speed at any height z in m s. Seismic importance factor i e and seismic use group.

And compression edge held in position with sheathing b d 6 7 laterally restrain ends both compression and tension sides. 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. 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. The design wind speed v z is given by v z v b k 1 k 2 k 3.

They are legally backed by the engineering profession. Structural engineering general discussion. Loads govern the lateral design of the building. Spectral response coefficients s ds and s d1.

Different design methods are used but they typically defined the load cases or combination stress or strength limits and deflection limits. Either way i think you should investigate the lateral load paths in this house. Mapped spectral response accelerations s s and s 1. Several of the tooling and casting requirements of a part can be addressed at the design stage.

K 3 topography factor. 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. How does a ridge beam prevent lateral pushout of home walls.
