説明
<p> Recently, from view-point of Global Environment, timber, i.e., one of nature-cycle materials, has been tried to be utilized as structural members of large timber buildings in Europe and North America. A representative timber of the members is Cross-laminated timber (CLT), however, CLT structural system very often restricts planning of building because of CLT being plate member. High-stiffness-strength-timber slender beam and column are significantly desired.</p><p> This study focuses a hybrid glulam timber with steel deformed bar (rebar) and Epoxy resin adhesive.</p><p> Aim of this study is to reveal elastic-plastic behavior of the hybrid timber column under lateral reversed cyclic loading, assumed to be attacked by a large number of big earthquakes. Column specimens were designed to yield at columnreinforced concrete foundation connection by bending.</p><p> The result of loading test and its discussion are summarized as follows:</p><p> (i) Proposed connection of column and foundation demonstrated potential of minimizing damage and final residualdisplacement and protecting degradation of hysteresis loop of the column even if reversed cyclic loading by 8-bigearthquakes was applied.</p><p> (ii) The final residual displacement drift was minimized to be less than 1/400rad., which can be neglected by the eye ofhuman, by quasi-static cyclic reverse loadings resembled free vibration to reveal the re-centring of the column afterthe bottom flexural yielded at earthquakes.</p><p> (iii) The hysteresis loops, indicated spindle shape with no pinching and abundant energy dissipation as never observedin RC columns.</p><p> (iv) The column has a region near interface between column and foundation, where bending stiffness for the hybridglulam timber cannot generate, and an assumption that bending stiffness at the region is degraded as Fig. 22(b), produces fairly good estimation of lateral stiffness of the column until its yielding.</p><p> (v) Lateral stiffness and loading capacity of the column produced approximately as much as those of a reinforced concretecolumn replaced wood with concrete of compressive strength 30N/mm2.</p>
