【Abstract】 In this paper,on the basis of simply reviewing design application of fiber reinforced concrete structure and principle of evaluation reliability of architecture structure,the authors analyzed site design response spectrum of ground motion and its indeterminacy.Subsequently the authors at first calculated the parameters of seismic reliability for a reinforced concrete plant,then gave the analogous parameters of seismic reliability for a fiber reinforced conerete plant.These parameters include content strength,stiffness,quality, indeterminacy and dynamic characteristic.The calculating result indicated that seismic reliability of fiber reinforced concrete plant was obviously bigger than reinforced concrete plant at the precondition of equivalent cost.So fiber reinforced concrete instead of reinforced conerete in architecture structure deserved further applying and spreading.更多还原
