Eng Tips Attic Lateral Design

Several of the tooling and casting requirements of a part can be addressed at the design stage.

Eng tips attic lateral design.

And compression edge held in position with sheathing b d 6 7 laterally restrain ends both compression and tension sides. Either way i think you should investigate the lateral load paths in this house. Where v z design wind speed at any height z in m s. If these requirements.

Seismic importance factor i e and seismic use group. Eng tips engineering forums is an intelligent work forum community for engineering professionals of all disciplines. Design wind speed up to 10 m height from mean ground level shall be considered constant. Design codes in general design codes are issued by a professional organization interested in insuring safety and standards.

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. Loads govern the lateral design of the building. 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.
