Assessment of international standard provisions on stiffness of reinforced concrete moment frame and shear wall buildings
https://orcid.org/0000-0002-8518-4464
Highlights Lateral stiffness provisions of leading international standards were evaluated for concrete buildings. Unique stiffness data from a four-story, full-scale concrete building tested on the E-Defense shaking table were used for the evaluations. Building stiffness was found to degrade substantially with increasing lateral drifts. Standard provisions did not capture well building stiffness and produced more accurate stiffness estimates for frame members than for walls. Improvements in the stiffness provisions of investigated standards for concrete buildings are warranted.
Abstract The accuracy of the lateral stiffness provisions of international standards is examined for concrete buildings. The stiffness provisions of American, Japanese, Canadian, New Zealand, and European standards are evaluated. Standard stiffness estimates are compared with the experimentally derived lateral stiffnesses of a four-story, full-scale, reinforced concrete building tested under multi-directional seismic motions on the Japanese E-Defense shaking table. The structure was designed to Japanese seismic design requirements and met most U.S. design requirements for regions of high seismicity. The building had moment frames resisting lateral loads in one direction and shear walls in the other. Building stiffness was found to degrade substantially with increasing lateral drifts and relate to prior deformation history. In general, standard stiffness values were higher than those of the building. Standard provisions produced more accurate stiffness estimates for frame members than for walls. All standard provisions produced substantially larger stiffness estimates than experimental values for shear walls. Study results therefore indicate that improvements in the stiffness provisions of all investigated standards for concrete buildings may be warranted.
