極限解析マクロモデルによる単独耐震壁の最大強度の解析精度(対角加力を受ける単独耐震壁の場合）

摘要

本研究では，既往の実験から収集した63体の単独耐震壁の試験体について，極限解析マクロモデルによる最大強度の解析を行い，モデルの妥当性と解析精度の検討を試みた。解析結果は柱梁のせん断強度を考盧しない解析で実験値/解析値の平均，標準偏差，および変動係数が，それぞれ1.004,0.133,および0.132であった。%This paper describes analysis accuracy of maximum strength of isolated framed shear walls by limit analysis macro model. This model is established from analysis output by elasto-plasticity analysis macro model. This model is considered based on the lower bound theorem of the limit-analysis theory. This model can apply shear strength of frames. This model guesses maximum strength of experiments with sufficient accuracy, even when shear strength of frames is not applied. Furthermore, if it is applied, accuracy became better. It is shown that these results are effective for evaluation of maximum strength of isolated framed shear walls by this model.
