説明
Current seismic resistant design strategy, including Performance-Based Earthquake Engineering (PBEE) requires accurate estimation of the seismic demand and capacity of structures, for which non-linear analysis has been employed for several decades in research and practice. However these analyses on member-basis have been almost indifferent to member models which represent damage distribution along the member. Girberson's one-component model is the most popular one which considers concentrated plastic rotational hinges at member ends. But the assumption is not necessary accurate enough for members of reinforced concrete, because plastic damage distributes due to cracking all through the member. In this study, results of non-linear static analysis (NSA) and non-linear dynamic analysis (NDA) are compared for four different member models. Girberson's one-component model is compared against the other member models for structural response parameters including, story drift demand and member force demand. It is revealed that one-component model overestimates maximum drift demand larger than compared different member models In NSA. Even including higher modes in lateral force distribution does not change the trend. However, member force demand estimated by the one-component model is larger than that by the other models. In NDA, one-component model underestimates the unevenness of drift demand smaller than other models and overestimates the unevenness of member force larger than other models in the intermediate stories.
