Eng tips attic lateral design.

Several of the tooling and casting requirements of a part can be addressed at the design stage. Design codes in general design codes are issued by a professional organization interested in insuring safety and standards. Design wind speed up to 10 m height from mean ground level shall be considered constant. 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.

Spectral response coefficients s ds and s d1. K 1 probability factor risk co efficient k 2 terrain height and structure height factor. How does a ridge beam prevent lateral pushout of home walls. Seismic importance factor i e and seismic use group.

Where v z design wind speed at any height z in m s. 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. 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. Either way i think you should investigate the lateral load paths in this house.

Mapped spectral response accelerations s s and s 1. The design wind speed v z is given by v z v b k 1 k 2 k 3. And compression edge held in position with sheathing b d 6 7 laterally restrain ends both compression and tension sides. Different design methods are used but they typically defined the load cases or combination stress or strength limits and deflection limits.

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. Structural engineering general discussion. They are legally backed by the engineering profession.
