| Popis: |
The ten-story full-scale shaking table tests conducted in 2015 and 2018 are simulated by analytical models such as being used in design practice or proposed in recent research and compared with the test data to simulate 1) the effective slab width on the beam capacities and 2) the base sliding and uplifting behavior. Three-dimensional pushover analysis used in the design practice of Japan was applied for the shake table tests with fixed base by varying the effective slab width on the beam to simulate the load-displacement relations and the lateral load carrying capacity in the tests. The effectiveness of slab and transverse beams was also evaluated in detail by the analysis with Timoshenko fiber beam element model applied partially for an outer span end in the wall direction. The analytical strains of slab reinforcement at the outer span end were compared with the measured in the tests. Three-dimensional nonlinear dynamic frame analyses with sliding base foundation models were carried out to simulate the responses of the superstructure and the sliding drift. Different types of simple base models were used where the two-way sliding and axial-shear interaction were considered at the center of the specimen while the horizontal base rotation was neglected. The response reduction of the superstructure owing to the sliding base could be approximated by either of base models, while still large discrepancy was observed in the sliding drifts among the test and the analyses. |
