| 摘 要： | 为更准确地分析混杂纤维增强复合材料（HYbrid FiberReinforced Polymer,HFRP）增强木梁的强度，选用双折线弹塑性木材本构关系，建立增强木梁的极限承载力计算模型。根据本模型可得到增强梁的中和轴高度、极限弯矩和极限承载力。选用已发表文献的数据作为模型输入得到的计算值与实验的实测值基本符合，差异在．13％～5％之间。

| Abstract: | In order to analyze the ultimate bearing capacity of wood beams strengthened with Hybrid Fiber Reinforced Polymer （HFRP） more accurately, a calculation model for predicting the ultimate flexural capacity of strengthened wood beams was build based on bilinear elastic-plastic timber constitutive relations. The neutral axis height, ultimate moment, and ultimate flexural capacity of the strengthened beams could be calculated from this model. The calculating results from the datum in a published literature showed a basic agreement with the test results, with the differences between -13% to -5%. |
