STRENGTH CALCULATION METHOD OF WOODEN EARTHQUAKE-RESISTANT WALL
To provide a strength calculation method of a wooden earthquake-resisting wall capable of properly evaluating various strengths.SOLUTION: A method for calculating the strength of a wooden earthquake-resisting wall including a wall body made of a CLT and having an upper end and a lower end of the wall body joined to an upper beam and a lower beam via beam joint parts, the method comprising the steps of: by assuming that a fracture load of the beam joint part is determined by collective fracture of the beam joint part caused by a crack generated in a CLT, setting a fracture cross-section at this time and setting a collective fracture region in which the collective fracture is caused by the set fracture cross-section; by assuming that a vertical load and a horizontal load act simultaneously on the beam joint, setting a load region in which the CLT is deformed by these loads; calculating at least one of a short-period load or an ultimate load as a fracture load of a fracture cross-section based on the set load region, fracture cross-section, collective fracture region, and tensile strength or shear strength of a lamina of the CLT.SELECTED DRAWING: Figure 12
【課題】各種強度を適切に評価することができる木質耐震壁の強度計算方法を提供する。【解決手段】ＣＬＴからなる壁体を備え、この壁体の上端と下端が上梁と下梁に梁接合部を介してそれぞれ接合された木質耐震壁の強度を計算する方法であって、梁接合部の破壊荷重が、ＣＬＴに生じる割れによる梁接合部の集合破壊で決定されると仮定して、この時の破壊断面を設定するとともに、設定した破壊断面により集合破壊する集合破壊領域を設定するステップと、梁接合部に対して鉛直荷重と水平荷重が同時に作用すると仮定して、これらの荷重によりＣＬＴが変形する荷重領域を設定するステップと、設定した荷重領域、破壊断面、集合破壊領域と、ＣＬＴのラミナの引張強度またはせん断強度に基づいて、破壊断面の破壊荷重として短期荷重または終局荷重の少なくとも一方を算定するステップを有するようにする。【選択図】図１２
