実大振動台実験に基づく木質系耐力壁構造の耐震性能に関する研究木質断熱複合パネル構造の動的基本性状と直交壁等の効果並びにエネルギー吸収性能

摘要

木質断熱複合パネル及び同パネルを用いた構法に混在する可能性がある耐力壁の振動実験を行い、考察した結果を以下に示す。（1）木質断熱複合パネル構造の動的基本性状を示すデータが得られ他の耐力壁構造との比較が可能となった。（2）応答倍率は各試験体共に概ね同様の傾向を示し、JMA神戸波では1階の塑性化により、BCJ波の値より小さく、且つ1、2階の差が小さくなる傾向があった。（3）耐力余裕率の増加に伴い、最大眉間変形角が小さくなる傾向が確詠されたが、両面せっこうボード壁は耐力余裕率で想定される以上に変形が小さかった。%This paper presents the results of the shaking table tests conducted on full-scale two stories timber constructions. The purpose of this study is to grasp of basic seismic performance of wood-framed structure with SIPs. Therefore, we made shaking table tests by very simple specimens and we conducted one-dimensional shaking table test mainly. The input motions used in the test are the BCJ-Levell and the JMA-Kobe 1995. The following main results obtained by this study are: 1) Waist-high walls and transverse walls have a effect of suppressing deformation by lateral forces. 2) The specimen of heq being over approximate l/30rad. goes down after maximum deformation angle. 3) Heq of wood-framed structure with SIPs on dynamic tests is higher than that of static tests. 4) Heq for wood-framed structure with SIPs calculated according to Building Standard Code is lower than the result of dynamic test.
