| Abstract: | The largest revision of the building code in Japan was released in 1981, in which the examination of ultimate lateral strength of structure is required. As a result, the capacity of the earthquake resistance of buildings is different between those designed before and after the revision of the code.The objective of this paper is to evaluate the seismic reliability of two groups of reinforced concrete buildings; one is the building group designed by the current code (after the 1981 revision) and the other is the building group designed by the former code (before the revision). The site is assumed to be Sendai city, Japan. Seismic reliability analyses of buildings are carried out and the probability of structural responses exceeding certain response levels during 100 years is evaluated for each type of building group. In addition to the uncertainty of earthquake forces, the uncertainties of structural characteristics, such as lateral resistance and the first natural period of structures, are considered based on the statistics of existing buildings. |
