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 spe...
