METHOD FOR EVALUATING SHEAR STRENGTH OF WALL

To provide a method for evaluating the shear strength of a wall, the method capable of appropriately evaluating the aseismatic performance of a wall with an opening ratio exceeding 0.4.SOLUTION: The shear strength of a wall is evaluated based on a design proof stress value obtained by multiplying a diagnostic criteria expression used in evaluating the shear strength of a wall with an opening ratio of 0.4 or less, by a reduction coefficient increasing according to the opening ratio. When the reduction coefficient is defined as α, and the opening ratio as η, the reduction coefficient is calculated by α=-1.5*η+1.6.SELECTED DRAWING: None 【課題】開口率が０．４を超える壁の耐震性能を適切に評価できる壁のせん断強度評価方法を提供する。【解決手段】開口率が０．４以下の壁のせん断強度を評価する際に用いられる所定の診断基準式に対し、開口率に応じて大きくなる低減係数を乗算した設計耐力値に基づいて、壁のせん断強度を評価する。低減係数をα、開口率をηとするとき、低減係数は、α＝－１．５・η＋１．６によって算出される。【選択図】なし
