摘要
指出了有关文献推导出的上下梁层间无销钉连接叠层梁弯曲应力计算公式是错误的,重新推导出了上下梁层间无销钉连接与有销钉连接的叠层梁弯曲应力计算公式,对学生正确理解和认识叠层梁弯曲实验有理论指导意义.
It was pointed out that the calculation formula for stress of laminated beam without pin joint in interlayer under bending experiment from relevant literature is wrong, and the calculation formulas for bending stress of laminated beam with or without pin joint in interlayer were rederived.It has theoretical guidance meaning for college students correctly comprehend and recognize the bending experiment of laminated beam.
