1. A structural beam or building panel assembly, the assembly comprising,
a cellulose-based cross-laminated timber (CLT) core, the core having generally planar upper and lower surfaces and comprising a plurality of laminated timber layers, each timber layer comprising a plurality of elongated timber members arranged in a substantially parallel array, an elongated orientation of the timber members of each array being oriented orthogonally relative to that of a next adjacent array,
at least one longitudinally extending channel extending inwardly into a top or bottom surface of said core,
an associated reinforcing assembly at least partially disposed in each said channel, each reinforcing assembly including a tensioning assembly,
grouting substantially encapsulating and securing said tensioning assembly positioned relative to said channel, and wherein each tensioning assembly includes,
an elongated sheath,
at least one tendon disposed within said sheath and extending longitudinally substantially along a length of the channel, wherein the sheath being selected to sufficiently isolate the at least one tendon from said grouting to permit post-tensioning of the at least one tendon following setting of said grouting, and at least one tendon anchor selectively engageable with an end portion of at least one said tendon to maintain said at least one tendon under tension in a selected tensioned state relative to said core.
