GWB, BMG, and CSB represent 12 mm gypsum wallboard, 12 mm bolivian magnesium board, and 12 mm calcium silicate board, respectively; 15, 20, and 25 are the edge distances often being used in the fields of interior stud, track, and end stud, respectively; f_e, d_e, f_y, d_y, f_p, d_p, f_u, and d_u are the elastic strength, yield strength, peak strength, failure strength, and their relative displacements, respectively; E_t and E_f are the test and calculated results of the hysteretic curve’s cumulative energy, respectively; the meanings of r_DispP, r_ForceP, and u_ForceP are identical to those in Figure 3.
