Abstract:

The bearing capacity and fireproof limit of SRC column will sharply descend considering the crack of outside concrete , so this optimal design method is based on fail-safe seismic design. By preassigning and pre-reinforced the position of outside concrete that will easily crack ,the optimal design method can guarantee the global stability of the structure and the personnel safety inside. Then verifying the method by theoretical derivation and large finite element analysis software ANSYS. The results indicate that preassigning and pre-reinforced the position of outside concrete do increase the stiffness and fireproof limit of the column , consequently ,increasing the security under the emergency of fire.

Key words: fail-safe seismic design, the finite element method, steel reinforced concrete column, fire-resistance performance
