Where v z design wind speed at any height z in m s.

Eng tips attic lateral design.

Eng tips engineering forums is an intelligent work forum community for engineering professionals of all disciplines. Different design methods are used but they typically defined the load cases or combination stress or strength limits and deflection limits. Loads govern the lateral design of the building. K 3 topography factor.

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

And compression edge held in position with sheathing b d 6 7 laterally restrain ends both compression and tension sides. Design codes in general design codes are issued by a professional organization interested in insuring safety and standards. Mapped spectral response accelerations s s and s 1. Structural engineering general discussion.

Either way i think you should investigate the lateral load paths in this house. K 1 probability factor risk co efficient k 2 terrain height and structure height factor. 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. Seismic importance factor i e and seismic use group.

If these requirements. Several of the tooling and casting requirements of a part can be addressed at the design stage. Spectral response coefficients s ds and s d1.
