摘要
木质建筑材料承压特征在强震状态下呈现出较强的非线性特征,对其特征分析难度较大。以细木工板建筑材料为研究对象,提出强震下细木工板建筑材料承压特征分析方法。设计建筑材料承压模型,确定承压特征,据此进行特征提取。模拟强烈震动环境,设计对比实验,结合提取的细木工板建筑材料承压特征,进行精度、适用范围和PS点相位分析,有效避免强震下的非线性对建筑材料特征分析的影响。结果表明,强震下的细木工板建筑材料承压特征分析方法,可在最短时间内定位断裂发生位置、确定断裂位置承压等级,也可对细木工板建筑材料性能进行精准评估。
It is difficult to analyze the pressure-bearing characteristics of wooden building materials,because of their strong nonlinear behavior under strong earthquakes.In this study,a method of analyzing the pressure-bearing characteristics of blockboard under strong earthquakes is proposed.A building material model is designed,and the pressure-bearing characteristics are determined,and then feature extraction is carried out accordingly.Subsequently,comparative tests are carried out under a simulated strong earthquake.Combining the extracted pressure-bearing characteristics of the blockboard building material,the precision,applicable range,and phase of PS point are analyzed.The results show that the pressure-bearing analysis method of the blockboard building material under strong earthquakes can determine fracture location and pressure level of location in the shortest time and accurately evaluate the performance of the blockboard building materials.
