【 摘 要 】

This paper is based on the ABAQUS finite element simulation software to study the seismic performance of the glass fiber reinforced polymer (GFRP) beam-column joint connected by the slotted-hole angle steel. Non-linear finite element analysis for the effect of slotted-hole on GFRP beams and different slotted-hole sizes on the seismic performance of joints were conducted. Four specimens D1, D2, D3 and D4 with different slotted-hole lengths were designed. The moment-rotation hysteretic curve, skeleton curve and energy dissipation curve of the specimen are obtained. The finite element analysis results show that: 1) the energy consumption of the slotted-hole joint is about 4%-21% higher than that of the ordinary circular hole joint. 2) The longer the slotted holes length is, the better the seismic energy dissipation performance is. The energy dissipation capacity increases by 3%-12% for each 2 mm increase in the slotted-hole length. 3) Although the larger the slotted-hole length is, the better the energy consumption is, the larger the deformation of the component will be caused. Therefore, according to the requirements of serviceability limit state, it is suggested that the slotted-hole length should be between 2 mm and 4 mm.
