英文摘要	To solve the stability of series seismic isolation system connected with column and coupling beam, which concerned engineering field, the critical load governing equation based on transfer matrix method was established. First, field matrix of stability on single laminated rubber bearing and point matrix of stability on coupling beam were established; Secondly, characteristic matrix of the stability on series seismic isolation system and the stability governing equation based on the characteristic matrix were established, which avoided tedious mechanical derivation; Finally, the stability of two kinds of series seismic isolation system using semi-analytic method was calculated, and influence of parameters variation on the stability of series seismic isolation system was investigated. The results show that it is not obvious for the added coupling beam to improve the two columns in series of critical load of the isolation system and the basement cantilever column scheme should be preferred in the lower part of the structure of the isolated building.
