Study On The Single Core-wall Suspension Structure Parameters And Seismic Time-history Analysis

Suspended building that conforms to nature laws is a new kind of structure systems. We can make full use of the high-strength building materials in this system. Because it can bring us large big room in the building, it is possible to solve the contradictory between usable function and structural construction. In suspended structure system the unity of safety, suitability and beauty, can be made benefit to the society and economy. This paper researches for suspended structure system as follows.ANSYS, a finite element analysis software, is used to establish the model of single core-wall suspension structure, then calculate the dynamic characteristics and seismic response. It remains in satisfactory agreement between the calculated results by using software ANSYS with the shaking table tests results. And then compared the seismic response between the core-wall structure and the suspension structure, the results show that the suspension structure has a better vibration-absorbing effect than the tube. It is shown that the seismic responses of the suspension structure are different under different seism. So when choosing the seism, we should choose the seism that has the first frequency of structure more. Finally, the seismic responses of the suspension, reamer structure and damper structure are calculated by the software ANSYS in time history analysis. The experimental data shows that the suspension structure has somewhat lower seismic displacement response and acceleration response at the top of the structure and even less when the dampers were fixed between the suspension stories and core- wall. So the suspension structure with dampers are good idea for shock absorption.
