In this wor.,we investigate a static and spher.cally symmetr.c b.r.een-Kiselev b.ack hole(b.)with the cosmological constant,which is a solution of the Einstein-non-linear.Maxwell field *** compute the quasinor.al fr.quencies for.the b.r.een-Kiselev b. with the cosmological constant due to electr.magnetic and gr.vitational *** var.ing the b. par.meter.,we discuss the b.havior.of b.th r.al and imaginar. par.s of the b. quasinor.al fr.quencies and compar. these fr.quencies with the r.issner.Nor.str.m-de Sitter.b. sur.ounded b. quintessence(r.-dSQ).Inter.stingly,it is shown that the r.sponses of the b.r.een-Kiselev b. with the cosmological constant and the r.-dSQ under.electr.magnetic per.ur.ations ar. differ.nt when the char.e par.meter.q,the state par.meter.w and the nor.alization factor.c ar. var.ed;however.for.the gr.vitational per.ur.ations,the r.sponses of the b.r.een-Kiselev b. with the cosmological constant and the r.-dSQ ar. differ.nt only when the char.e par.meter.q is ***,compar.d with the gr.vitational per.ur.ations,the electr.magnetic per.ur.ations can b. used to under.tand nonlinear.and linear.electr.magnetic fields in cur.ed spacetime *** inter.sting ob.er.ation is that,due to the pr.sence of Kiselev quintessence,the electr.magnetic per.ur.ations ar.und the b.r.een-Kiselev b. with the cosmological constant damps faster.and oscillates slowly;for.the gr.vitational per.ur.ations,the quasinor.al mode decays slowly and oscillates *** also study the r.flection and tr.nsmission coefficients along with the ab.or.tion cr.ss section in the b.r.een-Kiselev b. with the cosmological constant;it is shown that the tr.nsmission coefficients will incr.ase due to the pr.sence of Kiselev quintessence.

The selection and scaling of gr.und motion r.cor.s is consider.d a pr.mar. and essential task in per.or.ing str.ctur.l analysis and design. Conventional methods involve using gr.und motion models and a conditional spectr.m to select gr.und motion r.cor.s b.sed on the tar.et spectr.m. This r.sear.h demonstr.tes the influence of adopting differ.nt weighted factor. for.var.ous per.od r.nges dur.ng matching selected gr.und motions with the tar.et hazar. spectr.m. The event data fr.m the Next Gener.tion Attenuation West 2 (NGA-West 2) datab.se is used as the b.sis for.gr.und motion selection, and hazar. de-aggr.gation is conducted to estimate the event par.meter. of inter.st, which ar. then used to constr.ct the tar.et intensity measur. (IM). The tar.et IMs ar. then used to select gr.und motion r.cor.s with differ.nt weighted vector.valued ob.ective functions. The weights ar. alter.d to account for.the r.lative impor.ance of IM in accor.ance with the str.ctur.l analysis application of steel moment r.sisting fr.me (SMr.) b.ildings. Instead of an or.inar. ob.ective function for.the matching spectr.m, a novel model is intr.duced and compar.d with the conventional cost function. The r.sults indicate that when applying the new cost function for.gr.und motion selection, it places higher.demands on str.ctur.s compar.d to the conventional cost function. Mor.over. sub.itting mor. weights to the fir.t-mode per.od of str.ctur.s incr.ases engineer.ng demand par.meter.. Findings demonstr.te that weight factor. allocated to differ.nt per.od r.nges can successfully account for.per.od elongation and higher.mode effects.
