Dynamic Characteristics Analysis of High-rise Connected Structure

High-rise connected structure has been widely used in the country, at present research of its seismic behavior is less. In order to have a clear understanding for dynamic characteristics of high-rise connected structure, and improving the structure's seismic performance. This paper adopts the universal finite element calculating software to simulate and calculate high-rise connected structure, and gives natural frequency and vibration mode of high-rise connected structure, and analyses calculation results, research results can provides certain theoretical basis for seismic design of high-rise connected structure. The results showed that, high-rise connected structure is a more complex structure, vibration mode not only include transverse and longitudinal vibration mode, but also include reverse and space combination vibration mode. These show that high-rise connected structure's dynamic characteristics are more complicated.
