Shaking table tests of three-dimensional scale models of reinforced concrete high-rise frame structures with wall columns

Abstract

The objectives of these tests were to understand the behavior of high-rise frame structures with wall columns (HFW system) during an earthquake, and to validate an analytical model with the test results. Two one-seventh-scale, 11-story HFW models were tested on a shaking table. One model was excited in the longitudinal direction only, and the other model was excited simultaneously in both the longitudinal and transverse directions. These tests indicate that under one-way excitation, the test model failed in flexure at the girders, and under two-way excitation, the test model failed in flexure at the walls and girders. Calculated values of maximum shear strength from the analytical model were close to the test values in the longitudinal direction when either one-half or the full width of the transverse bay length was assumed as the effective flange width.
