Diaphragm Action Of Timber Floors

Traditionally timber diaphragms consist of wooden sheathing on light timber framing see figure 1.

Diaphragm action of timber floors. A shear wall however is a vertical cantilevered diaphragm. This construction type has been used for floors and for large panelised roof systems for industrial buildings. Diaphragms are usually constructed of plywood or oriented strand board in timber construction. A diaphragm acts in a manner analogous to deep beam or girder where panels acts as web resisting shear while diaphragm edge members does the function of a flange resisting bending stress.

This study provides an appraisal of the diaphragm action of such full size wood building components as floors roofs and walls. For wood structures diaphragms are commonly constructed of wood structural panel wsp sheathing or decking applied to the upper face of regularly spaced floor or roof wood framing members such as joists trusses purlins or sub purlins. The diaphragm of a structure often does double duty as the floor system or roof system in a building or the deck of a bridge which simultaneously supports gravity loads. Our anchored floating or parquet floor systems exceed expectations and help sports teams win.

Diaphragm is horizontal or nearly horizontal system acting to transmit lateral forces to the vertical resisting elements. A horizontal system roof floor or other membrane or horizontal bracing acting to transmit lateral forces to vertical resisting elements.

The term diaphragm includes horizontal bracing systems. The construction of the panels. Or a concrete slab in concrete construction. Diaphragms are a roof floor or other system transferring lateral forces applied to a building to the vertical elements such as the shear walls.

The term diaphragm is usually applied to roofs and floors. Structures using wood frame shear walls or wood frame diaphragms to resist wind seismic or other lateral loads shall be designed and constructed in accordance with af pa sdpws and the applicable provisions of sections 2305 2306 and 2307. The rigid diaphragm can rotate and it can translate but cannot deform. The lateral forces will be distributed redistributed at the subsequent levels based upon the relative stiffness of all the members resisting lateral.

These construction systems can be used when designing a building for lateral loads such as those generated by wind or earthquakes. A diaphragm is a flat structural unit acting like a deep thin beam. There are two popular types of diaphragm namely rigid diaphragm and semi rigid diaphragm. 5 2012 ibc 2306 2 wood diaphragms 2306 2 1 wood frame structural panel diaphragms.
