| Abstract | ||
| This paper studies seismic performance of a tall full-frame building with a thick-slab transfer substructure on depot. The thick- slab transfer substructure is comprised of the reinforced concrete shear wall, the reinforced concrete frame and the concrete thick transfer slab. A prototype with a scaling ratio of 1:15 is designed and fabricated to feasibly test and to reasonably assess structural dynamic characteristics under different earthquake intensities. The earthquake intensities are simulated by wave vibration of 0.118 g, 0.337 g, 0.741 g, and 1.347 g on a shaking table. A finite element analysis (FEA) model is developed and verified with the experimental results. The test results show that the superstructure is yielded before the substructure failure, whereas the reinforced concrete frame structure is intact under the excitation of peak ground acceleration of 1.347 g. The verified FEA model is used to investigate three structural layout angles of 60o, 45o and 0o. The structural seismic behaviors of the different layout angles between the reinforced concrete shear wall and the reinforced concrete frame are discussed. The FEA results show that the dynamic responses are significantly affected by layout angles of the single tower. | ||
