Abstract: To study the seismic behavior of the cold-formed thin-walled steel shear walls of using self-piercing rivets with openings, 8 full scale of 3 m×2.4 m (height by width)specimens were tested under monotonic loading and cyclic loading, respectively. Factors that influence the seismic behavior of cold-formed steel stud walls including loading pattern and opening ratio were studied, and the failure mechanism bearing capacity stiffness ductility and energy dissipation coefficient of specimens were obtained. Results show the shear resistance of the cold-formed thin-walled steel shear walls of using self-piercing rivets with openings under monotonic loading is higher than that of the low-cycle reciprocating loading. However, with increasing the size of the hole, the influence of the loading method of the shear resistance is weakened. The damage of the wall specimen mainly occurs at the corner of the wall and both sides of the opening. The ductility coefficient of the wall is between 1.67 and 3.36;the coefficient of energy dissipation is between 0.60-0.73. With increasing the wall hole size, the ductility increases, and the wall lateral stiffness and the bearing capacity decrease.
