A Study on the Structure Analysis including the Creep and Shrinkage Effects |
| Abstract |
In case of commercially available structural analysis program, all load is assumed to be applied to the structure after the completion of whole building. The real high-rise building, however, is constructed and partially loaded story by story. Here one can easily expect that long term behavior will be different from that of analysis model. Long term structural behaviors can be predicted by adopting analysis models. But the predicted behaviors are influenced much by the selected models, among which ACI, CEB-FIP and B3 model may be noticeable. In this paper, the long term behaviors of reinforced concrete high-rise frame structures due to creep and shrinkage are investigated by finite element method, where above mentioned 3 models are adopted. The change of stress by adopted models rapidily developed at the early age after the completion of whole building. |
