Kwon & Elnashai (2006) - LFM+DNO_HEX:3 (Low ratio a_v)

Description

Name: Kwon & Elnashai (2006) - LFM+DNO/HEX:3 (Low ratio a/v) | General comments: Sample Data. Buildings: 3 storeys ordinary moment resisting reinforced concrete frame. The structure was designed for gravity loads following ACI 318-89 provisions, and it is non-seismically detailed. The verification of the analytical model is taking into account through comparison with shaking table experiments. Seismic hazard: recorded (three sets of ground motions) and artificial accelerograms (six set of ground motions). Uncertainties: The effects of aleatory uncertainties from material (normal distribution of concrete and steel strength) and ground motion on the vulnerability curves are investigated. The effect of randomness in material response parameters is far less significant than the effect of strong-motion characteristics. One curve for each set of ground motions used is shown in order to demonstrate the difference in fragility due to the strong motion characteristics. The limit state are defined for the prototype structure and ISD is used as the global measure of damage: Serviceability --> 0.57% ISD (first yielding of steel) Damage control --> 1.2% ISD (attainment of maximum element strength) Collapse --> 2.3% ISD (maximum concrete confined concrete strength) Valid for: USA
