000009484 520__ $$2eng$$aThe effect of uncertainty in structural parameters on the response of a single-storey torsionally-coupled building subjected to stationary stochastic ground motion is studied here. A reliability-based formulation, where failure is defined as the exceedance of a predetermined value of the response quantity of interest, is used and solved using a first-order-reliability method (FORM). The responses of interest are the displacements on the stiff and flexible side edges, and the base shear and torque at the center of mass. The structural parameters considered uncertain are the uncoupled lateral and torsional frequencies, and the eccentricity, which are assumed to be statistically independent of each other. However, the structural response is also a random variable that depends on the structural parameters, and this requires special consideration in the reliability analysis. It is seen that the 84-percentile and 95-percentile responses are significantly affected by the uncertainty in structural parameters, especially when lateral-torsional coupling is significant. These effects are more for small eccentricity and damping ratios. The uncertainty in parameters significantly increases responses, especially when lateral-torsional coupling in large. These effects are larger for displacements on the flexible side.
