Abstract


With the development of the requirement of commerce and dwelling house, the span of those structure are called for more and more. There are some questions in practice: could reinforced concrete beam exceed 15 meters without increasing the height of the beam? To satisfy the need of structure, could dispose pipe (like pipe of air-condition) in the range of traditional height of the beam without changing the height of the beam? Through decreasing the height of beam and disposing cable under the beam, some people advanced a new structure: cable-concrete beam.The structure of cable-concrete beam is a new type of structure, composed of string, strut and moment-resistant element such as beam, arch, and it is a self-balance structure with metrics of rationally mechanical characteristics, convenience of execution and transportation. And this structure will have great prospect.In this dissertation, based on the existing researching finding on BSS, taking use of the large common finite element program ANSYS, the anti-seismic characteristics are studied as following:1) The paper works on the static response analysis of cable-concrete beam through ANSYS. After this, several parameters which influence the static characteristics of this structure are also discussed.2) The finite element model of a two-story frame with cable-concrete is formed through reasonable simplification. Then, the author works on the dynamic response analysis of cable-concrete beam through ANSYS. In the end, the paper discusses several parameters which influence the static characteristics of this structure.3) Based the research above, the paper derives the seismic response of structure through transient dynamic analysis of a frame by ANSYS.
