| Abstract: | Invariability of reinforced concrete frames are studied in the paper, in which 2 T-shape reinforced concrete frames are tested under monotone loading and other 4 T-shape reinforced concrete frames are done under lower-cycle lording. Factors to affect the invariablility of the reinforced concrete frame are studied. The calculating method about the stiffness of the reinforced concrete frame in the invariable state is discussed and the formula based on the wedge-shape alterable stiffness method for the inner force of the reinforced concrete frame in the invariable state is put forward. |
