脚部に鋼板挿入ドリフトピン接合を用いたCLT耐カ壁構面のせん断性能評価

摘要

Load-deformation angle relationships of Cross Laminated Timber (CLT) shear walls were evaluated by horizontal loading test, as well as using incremental displacement analysis. The drift-pined joints with steel plate were used for the leg joints. In the elastic region, the ratio of deformation angle caused by joint deformation against total deformation of the wall was about 50%.The shear elastic modulus of five layered 150mm thickness CLT panel was 661N/mm~2 in average. The failure of shear wall depends on the joint Shear failure between perpendicular and parallel layers was observed. The estimations by incremental displacement analysis matched test results well.%脚部に鋼板挿入ドリフトピン接合を用いたCLT耐カ壁の水平載荷実験および增分解析を行い、面内性能及および接合性能の検討を行った。①脚部接合部の変形に対して、曲げやせん断によるCLT耐カ壁の面内変形の占める割合は大きい。とくにP-Yが弾性範囲内においては著しく大きい。②CLTの面内曲げ弾性係数は平行層のみを考慮することでおおよそ推定できる。
