This translation is the key to any structural sizing . This type of beam is constructed monolithically with a reinforced concrete slab at the perimeter of the structure, as illustrated in Fig. In an exploration of hybrid construction, the Virtuoso project at the University of British Columbia uses mass timber and light wood frame elements. Timber -- End splits -- Structural Engineering -- Beam -- Shear strength -- Fatigue test. The first step is the same for sawn- and engineered wood materials: add up all the loads acting on a header or beam and then translate this load into terms of how much load each lineal foot of header or beam will feel.
