Probabilistic Characteristics of Residual Displacements of SDOF Systems

Abstract:

Probabilistic residual displacement analysis plays an important role in determination of technical or economical feasibility of repairing the damaged emgineering structures after an earthquake. Probabilistic characteristics of residual displacements of SDOF systems were quantificationally investigated in this study through a comprehensive statistical analysis. The influences of the P-Δ effect, period of vibration, normalized yield strength and post-yield stiffness ratio on probabilistic characteristics of residual displacements were investigated based on 69 selected earthquake records. In particular, the probability models for the normalized residual displacements were proposed and tested. Results show that the P-Δ effect and post-yield stiffness ratio have significant impacts on the residual displacements; the period of vibration also obviously influences the residual displacements for rigid systems; the residual displacement can be described as the Lognormal distribution variable.
