摘要
FRP(纤维增强复合材料)是一种新型绿色建筑材料,具有强度高、质量轻、耐腐蚀性强等特点,在建筑工程中得到广泛应用。通过对FRP空调支架和防护栏杆进行有限元分析,研究FRP空调支架的疲劳性能,分析FRP防护栏杆的抗冲击性能。结果表明,FRP空调支架具有良好的耐疲劳性能,螺栓孔位置是影响FRP空调支架疲劳寿命的薄弱处;FRP防护栏杆具有良好的抗冲性能,且在撞击后栏杆能够较快速地恢复形状。因此,FRP绿色建筑附属部品部件具有良好的力学性能和耐久性能,能够满足恶劣环境下工程使用要求,对FRP绿色建筑材料的推广应用具有重要意义。
FRP(fiber reinforced polymer)is a new type of green building material with high strength,light weight,and strong corrosion resistance,which has been widely used in construction engineering.The fatigue performance of FRP air conditioning brackets is studied through finite element analysis,and the impact resistance of FRP protective railings is analyzed.The results show that the FRP air conditioning brackets have good fatigue resistance,and the bolt hole position is the weak point that affects the fatigue life of the FRP air conditioning bracket;FRP protective railings have good impact resistance and can quickly restore shape after impact.Therefore,FRP green building accessory components have good mechanical and durability properties,which can meet the requirements of engineering use in harsh environments.It is of great significance for the promotion and application of FRP green building materials.
