This paper gives the seismic reliability indexes of four multistory dwelling brick buildings with and
without laminated rubber bearings in given regions of intensity YE, VI and IX by Latin Hypercube
Sampling technique and nonlinear seismic time history response analysis. Through the comparison of
the seismic reliability indexes of the brick buildings with and without isolation, three results are
obtained as follows:
(1) The isolated brick buildings built in higher intensity region have better seismic performance than in
lower intensity region.
(2) Compared with the brick buildings without isolation, the isolated brick buildings can be designed
with 1 intensity lower than the basic intensity, and the story number of the isolated brick building
can be broken through the limit of the code, such as a six-story isolated brick building may be
designed in region of intensity IX and a seven-story isolated brick building in region of intensity
VHI.
(3) Compared with the brick buildings without isolation, it is no problem that the isolated brick
buildings can be designed with 1 intensity lower than the basic intensity and increasing 1 story,
and it can assure that the isolated brick buildings designed in this way have higher seismic safety.
These results provide basis for the design of multistory isolated brick buildings. This method can also
be used in the seismic reliability analysis of other isolated building structures.
