bearing requirements on the wall plates, or bearing-plate sizing in beam and column design. Where joists, beams, or studs bear on supports, some fiber deformation develops, requiring the bearing area to be of sufficient size to prevent excessive side grain crushing of the joists, beams, or ...
Performance curves and design charts developed using this procedure could be used to determine limits on the seismic weight to ensure target non-exceedence probabilities for the different specified performance (drift) levels. Implications for design are discussed and one example o...
Intensive shear can damage the fibres causing fibre breakage that will decrease the aspect ratio that is an important determinant of mechanical properties. Screws and dies with specialised custom design may be required for a particular composite. 6.5.2 Extrusion to provide special textures The ...
We love the Woodmaster’s 3-Side Molding System. To make our flooring, for example, we’ll put a hardwood blank through the machine and it cuts three sides in one pass: the tongue, the groove, and the back relief cut. With the Woodmaster we have set up as a molder, we have Wood...

For example:to builda king size bed frame, just add 16 inches to the length of all the horizontal components: the 1x4s, 2×4 and 2×6 on the headboard, the bed slats, and the 2×6 on the headboard. To builda twin size bed frame, reduce 21 inches on the length of all the hori...

Note that these are not the specimen type required for ASTM tests on wood, as the intent is to demonstrate tensile behavior and not to develop a database for design. Proceed as normal with the usual tension test machine (see second manuscript on this series: Tensile Tests on Steel). ...
Shear walls coupled with yielding shear links were developed in New Zealand in the 1980s after successful tests carried out by Park and Paulay (1975). This coupled-wall system is another excellent example of creative research to develop a low-cost mechanism for seismic energy dissipation. Active...
Wood itself is made from elastic structures, with cork being a most prominent example. Cork is a kind of natural elastic material, which is derived from oak (Quercus suber L.) tree bark [26], [27]. Indeed, the bark of an oak tree consists of several layers, one of which is the cor...
