Challenges in Base Shear Estimation from Recorded Motions
This paper examined if the base shear computed from summation of floor inertial forces above the building's base can provide an accurate estimate of the true base shear. For this purpose, response of a 20-Story Reinforced-Concrete Hotel in North Hollywood and a 19-Story Steel Office Building in Los Angeles were computed from response history analysis (RHA) for a suite of 30 ground motions recorded during past earthquakes. The estimated base shear was then compared with the true base shear. It was found that the estimated base shear exceeds the true base shear in the median by 10% to 20%. For individual earthquakes, however, the estimated base shear may exceed the true base shear by as much as 75%. Therefore, the base shear computed from floor inertial forces should be used with caution as an indicator of the true base shear.
