摘要:

基于非线性本构关系和不同材料的特性,利用Ansys软件中的有限元分析,精确地模拟了指接木梁模型的损伤行为和力学性能.结果表明,CFRP增强了木梁极限承载力,且极限应力主要集中在CFRP材料上.

关键词: 构件模型, 指接头, 指接木梁, CFRP

Abstract:

Based on finite element analysis (FEA) in Ansys software,a numerical simulation is proposed to accurately describe the damage behavior and mechanical performance of the model.The results show that the ultimate bearing capacity is increased by CFRP.The stress is mainly concentrated on the CFRP material.

Key words: component model, finger joint, timber beams, carbon fiber reinforced polymer
