碳纤维板加固预应力空心板受力性能分析

摘要

The paper establishes finite element model of prestressed carbon fiber board and common carbon fiber board reinforced prestressed hol-low board by applying MIDAS/FEA,considers secondary stress impact,and compares and analyzes its reinforcement effects. The analysis results show some suggestions for similar bridge engineering reinforcement with carbon fiber board.%采用MIDAS／FEA建立了预应力碳纤维板和普通碳纤维板加固后预应力空心板有限元分析模型，并考虑二次受力的影响，对其加固效果进行了对比分析，依据分析结果给出了工程中使用碳纤维板加固类似桥梁的建议。
