To study the brittleness index change of basalt fiber reinforced concrete (BFRC) and input energy, elastic energy and dissipative energy evolution law under cyclic loading at different confining pressures, triaxial compression tests and cyclic loading tests at different confining pressures (i.e. 5, 10, 15, 20 and 30 MPa) were carried out in a model MTS816 Rock Test System, and the energy drop coefficient was introduced to express the BFRC brittleness index. The results of triaxial compression test show that except 5 MPa, the drop coefficient of BFRC at other confining pressures is increased by 1.26, 2.03, 2.77 and 4.24 times, respectively. Based on the results of cyclic loading test results, when the cycle is controlled by displacement, the unloading point at the post-peak stage can be obtained according to the set displacement value instead of the peak stress point of a single cycle. The energy evolution curve of BFRC has obvious stage characteristics, and the energy value of a single cycle is closely related to the loading and unloading points. The stable state of BFRC can be indirectly judged by a ratio of elastic energy to dissipative energy.
