A Time Variant Approach to Performance-Based Engineering Conference Paper uri icon

abstract

  • This study presents an overview of an approach that identifies a design earthquake in terms of a critical response spectrum at a site in order to estimate the time variant reliability of the structure against exceedance of a specified inter-story drift. This is accomplished by coupling a technique similar to Probabilistic Seismic Hazard Analysis (PSHA) with performance-based reliability. Once the critical response spectrum is identified in terms of earthquake magnitude, M, and site-to-source distance, R, Monte Carlo Simulation (MCS) is used to account for spectral scatter, and structural resistance uncertainty present in the mass, stiffness, and damping of the model. An illustrative example is included for clarity. This example combines MCS with response spectrum analysis to estimate the static reliability of the structure. Then, the return period of the design earthquake is determined by definition and the time interval of interest is modeled as Poisson with a mean proportional to the length of the interval, and the time variant reliability of the structure determined.
