【摘要】 为了解重组竹梁的受弯力学性能,用加筋的SOLID65单元分析两种工况下重组竹梁4点受弯时的承载力和竖向位移,材料的应力-应变关系曲线和相关的力学特性采用小试件的试验结果,得到重组竹梁的应力云图和跨中梁的荷载-位移曲线。同时,2组4根重组竹梁采用与数值分析相同的荷载工况进行试验。结果表明,数值分析结果和试验结果吻合较好。验证了应用ANSYS软件对重组竹梁进行数值模拟分析的可行性。更多还原

【Abstract】 To understand the bending mechanical performance of parallel strand bamboo(PSB)beams,the SOLID65 element was empolyed to analyze the bending bearing capacity and vertical displacement of PSB beam under two load conditions in the way of four-point bending in this study.The stress-strain curve of material and relative mechanical performance were based on the testing results of small net member.The stress cloud figure and the curve of load-displacement were obtained,and four PSB beams within two groups were evaluated under the same load conditions as in the numberical analysis.The tested results were compatible with the results of numerical analysis.It confirmed that ANSYS software was feasible for the numerical stimulation of PSB beam.更多还原
