  • This study aims to determine a proper input number of strong motion recordings for structural time-history analysis in China seismic design code. The cumulative probability curves of structural response under different number of records were simulated using 500 times of Monte Carlo samplings based on the assumption that the seismic demand can be represented by a lognormal distribution. Consequently, significant difference was observed in cumulative probability curves between using the maximum response of three ground motions and using the average response of seven or more ground motions: in the former, the expectation of results is much higher than the theoretical mean structural response and is significantly affected by the structural response variation; while in the latter, the expectation of results is close to the theoretical mean structural response. In addition, nonlinear time-history analysis was carried out of a 10-story typical reinforced concrete (RC) frame according to Chinese seismic code. It turns out that using three records has a significantly higher mean MIDR (maximum inter-story displacement angle) and COV (coefficients of variation) compared with other schemes using more records as input and controlling the record-to-record variation. Finally, on the basis of the response mean values of seven or more strong vibration records, an empirical correction formula using record number and structural response variation as parameters was proposed to calculate the 0.84 quantile value to guarantee the assurance rate of 84% required by seismic design code. The applicability of the empirical correction formula under the seismic code of China is verified by numerical simulation of the 10-story RC frame.
