SHAKING TABLE TESTS OF 3-DIMENSIONAL SCALE MODELS OF REINFORCED-CONCRETE HIGHRISE FRAME STRUCTURES WITH WALL COLUMNS

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