A general nonlinear m.th.m.tical m.del for th. viral infection with.h.m.ral im.unity and two distributed delays is proposed and analyzed. Two bifurcation param.ters, th. basic reproduction num.er, R0 and th. h.m.ral im.unity num.er, R1 are derived. We establish.d a set of conditions on th. general functions wh.ch.are sufficient to determ.ne th. global dynam.cs of th. m.del. Utilizing Lyapunov functions and LaSalle＇s invariance principle, th. global asym.totic stability of all equilibria of th. m.del is obtained. An exam.le is presented and som. num.rical sim.lations are conducted in order to illustrate th. dynam.cal beh.vior.

Th. effects ofincoh.rency and wave-passage on th. nonlinear responses of concrete arch.dam. are investigated in th.s study. A double curvature arch.dam.is selected as a num.rical exam.le. Th. reservoir is m.deled as a com.ressible m.terial and th. foundation is m.deled as a m.ssless m.dium. Ground m.tion tim.-h.stories are artificially generated using th. m.nte Carlo sim.lation approach. Four different finite elem.nt m.dels （FEm. are considered： uniform.excitation; incoh.rence effect; wave passage effect; and both.incoh.rence and wave passage effects. It was revealed th.t m.deling m.ltiple-supports excitation could h.ve a significant im.act on th. structural response of th. dam.by inducing a pseudo-static effect. Also, it was concluded th.t th. coh.rency effect oversh.dows th. wave passage effect and th. results obtained from.non-uniform.excitation of FEm. including th. wave passage effect, is close to th. results of th. FEm.wh.n it is uniform.y excited.
