Least Favorable Probability of Failure for 5- and 10-story RC Frame Structures with Vertical Irregularities
This article evaluates the seismic control effect of vertical irregularity factors for RC frame structures using the Monte Carlo simulation method. Typical 5- and 10-story frame structures with different irregularities of strength or stiffness are assessed. The upper- and lower-bound probabilities of failure exceeding the limit state are studied. The results indicate that the exceeding probability increases as the vertical irregularity factor decreases. The upper-bound probability of failure, which is sensitive to the vertical irregularities and is an effective indicator for evaluating the performance control parameter, is significantly larger compared with the lower-bound probability of failure. A minimum strength and stiffness irregularity factor of 0.7 can serve as the seismic control limit.
