Energy evaluation of inelastic structures subjected to random earthquake excitations
10.1002/tal.455.abs
The modified force analogy method combined with static condensation is applied to study the seismic behaviour of inelastic structures, while energy transfer and dissipation in the structure during an earthquake hazard are investigated through energy formulation based on the equation of motion. The earthquake ground motion is modelled as a non‐stationary Gaussian random process. Rigid‐end offsets of the plastic hinges forming on the members, as well as the ability for panel zones to deform, are included in the structural analysis model. Monte Carlo simulation method is performed on a six‐story real moment‐resisting frame to determine the mean and the standard deviation of seismic energy dissipation time histories. Based on this combination of the force analogy method and energy formulation in the equation of motion with the stochastic earthquake model, the feasibility of the analysis procedure for studying the dynamics of inelastic structures is demonstrated through varying the rigidity of panel zones.
