Random vibration of hysteretic systems under bi-directional ground motions
TLDR
In this paper, a random vibration method is developed for the response analysis of hysteretic structural systems under stochastic two-dimensional earthquake excitations, where the biaxial restoring force is modelled by coupled nonlinear differential equations; the response statistics are obtained using the equivalent linearization technique.Abstract:
A random vibration method is developed for the response analysis of hysteretic structural systems under stochastic two-dimensional earthquake excitations. The biaxial hysteretic restoring force is modelled by coupled non-linear differential equations; the response statistics are obtained using the equivalent linearization technique. The validity of the proposed model is appraised using available biaxial loading tests of reinforced concrete columns. A parametric study was performed to examine the significance of the effects of biaxial interaction under earthquake excitations. A practical method to evaluate the extreme response statistics is also presented.read more
