###### Abstract  
To replace conventional concrete with coal gangue concrete in the construction industry, lateral cyclic loading tests were applied to three shear walls with different coal gangue replacement rates in this study, in which the replacement rate of coal gangue was 0%, 50%, and 100%. The load-displacement hysteretic curves and backbone curves of the shear walls obtained from tests were analyzed to compare the failure process and seismic performance of each shear wall. The results indicate that the stress performance and failure morphology of coal gangue concrete shear walls and conventional concrete shear walls are extremely similar, and the characteristics of the hysteretic and backbone curves are approximately the same. With the increase in the coal gangue replacement rate, the bearing capacity and ductility of the three shear walls gradually decrease, the strength degradation gradually becomes significant, and the energy dissipation capacity becomes worse, but the difference is not obvious, and all of them can meet the requirements of seismic performance. In addition, with the increase in the coal gangue replacement rate, the stiffness degradation gradually slows, so it is feasible to construct a shear wall using coal gangue concrete instead of conventional concrete.

and tested its basic properties. It was found that it is feasible to replace conventional coarse aggregate with coal gangue [6; 7; 8]. [PERSON] et al. [9; 10; 11] tested the mechanical properties of concrete prepared using coal gangue and proved that it meets mechanical properties requirements. The new thermal insulation concrete prepared by [PERSON] et al. [12] using coal gangue can still meet the strength requirements under the condition of large thermal conductivity. [PERSON] et al. [13; 14] proved that the strength of coal gangue concrete is related to the gradation of coal gangue, and the mechanical properties can be improved by adding steel fiber. [PERSON] et al. [15] found that calcined coal gangue can improve the strength of coal gangue concrete. In addition, [PERSON] et al. [16; 17] studied the crack resistance of C30 coal gangue concrete caused by drying shrinkage in different environments and different contents of spontaneous combustion coal gangue as test variables. [PERSON] et al. [18; 19] studied the water absorption performance of coal gangue concrete under different times and different coal gangue replacement rates and studied the durability of coal gangue concrete under different pH values. Nowadays, structural health monitoring has become an important method to ensure the safety of structures [20]. Because the basic properties of coal gangue concrete research are more mature, coal gangue concrete has gradually been applied to structures by scholars. [PERSON] et al. [21] carried out a low-cyclic reciprocal load test on six reinforced coal gangue concrete low shear walls and studied the influence of the shear span-to-depth ratio, concrete strength, and reinforcement ratio on the seismic performance of coal gangue concrete low shear walls. At the same time, the calculation formula of the shear bearing capacity of a coal gangue concrete low shear wall was proposed [21]. [PERSON] et al. [22] carried out a finite element simulation of coal gangue concrete-filled steel tubular beam-column joints under reciprocating loads. The results show that the joints have excellent seismic performance and show good ductility and energy dissipation performance [22]. [PERSON] et al. [23] carried out a static test of four reinforced coal gangue concrete beams and found that the stress form and failure process of reinforced coal gangue concrete beams are similar to those of conventional reinforced concrete beams. Furthermore, the constitutive relationship formula of coal gangue concrete was proposed [23]. [PERSON] et al.
