Eng tips attic lateral design.

How does a ridge beam prevent lateral pushout of home walls. 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. 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. Loads govern the lateral design of the building. Structural engineering general discussion. They are legally backed by the engineering profession.

K 1 probability factor risk co efficient k 2 terrain height and structure height factor. Design wind speed up to 10 m height from mean ground level shall be considered constant. Either way i think you should investigate the lateral load paths in this house. 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.

If these requirements. Seismic importance factor i e and seismic use group. 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. Eng tips engineering forums is an intelligent work forum community for engineering professionals of all disciplines.

Where v z design wind speed at any height z in m s. Different design methods are used but they typically defined the load cases or combination stress or strength limits and deflection limits. 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.
