Shake-Table Test of a Full-Scale 4-Story Precast Concrete Building. II: Analytical Studies
Publication: Journal of Structural Engineering
Volume 143, Issue 6
Abstract
In 2010, a full-scale, 4-story precast concrete building was tested on the E-Defense shake table. The lateral-force-resisting system of the building included unbonded posttensioned (UPT) concrete walls in one direction and bonded posttensioned frames in the orthogonal direction. The companion paper presents an overview of the experimental program and key test results for response in the wall direction; this paper describes the development and experimental verification of a nonlinear model in the wall direction of the test building using commercially available software. The good correlations between analytical and experimental results confirm the ability of the model to capture global and local responses, including story lateral displacements, story shear forces and moments, and gap opening due to rocking at the wall base. Test and model results provide valuable insight into dynamic responses and design aspects of a full-scale, three-dimensional UPT building, including the influence of component interactions and the role of the floor diaphragm.
