Eng tips attic lateral design.

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. If these requirements. The design wind speed v z is given by v z v b k 1 k 2 k 3.

Seismic importance factor i e and seismic use group. Either way i think you should investigate the lateral load paths in this house. Several of the tooling and casting requirements of a part can be addressed at the design stage. Different design methods are used but they typically defined the load cases or combination stress or strength limits and deflection limits.

Structural engineering general discussion. K 3 topography factor. Loads govern the lateral design of the building. Where v z design wind speed at any height z in m s.

Mapped spectral response accelerations s s and s 1. 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. 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. How does a ridge beam prevent lateral pushout of home walls. K 1 probability factor risk co efficient k 2 terrain height and structure height factor.
