Presently, the inelastic behaviour of a high-rise building during an earthquake is accounted for by dividing the elastic earthquz factor. This factor is chosen from a table in the Eurocode 8 and represents a gross simplification of the actual behaviour of It currently used by industry to improve the assessment of the inelastic capacity of a high-rise building is the push-over analysi of applying this analysis to high-rise buildings where the fundamental mode of vibration does not dominate the response have aim of this work is art initial study into developing a methodology for determining behaviour factors for high-rise buildings sub, The methodology will be developed by producing a simplified model to perform non-linear, time-history analysis and then this the influence of higher order modes on push-over ananlysis. To calibrate the simplified model, static, non-linear, finite eleme developed. Static results from the benchmarks will be compared with the simplified model and hence the model will be verif model has been verified, building configurations will be analysed with the model. Examples wilt be chosen where the higher c contribute significantly to the overall response of the structure. Using the new model, the influence of the higher order mode push-over analysis will be investigated and quantified. This will allow designers to employ push-over analysis on buildings tl fundamental mode of vibration. In addition to this, the new model will be used for an initial investigation to develop a methodfactors for individual buildings. Keywords Engineering Dynamics, Er
