Sažetak
As a member of the highway transportation network, the small bridge has the advantages of simple structure, clear stress, durability, and strong applicability. It is still used in a large number of road network applications. With the development of the bridge business, the number of fires on the bridges has also increased, and the damage caused to the bridges after the fire has also been considerable. The destruction of any component of the road network will affect the normal operation of the entire traffic. This article provides a quick scientific assessment method for small bridges after a fire, including the rapid estimation of fire high temperature based on the fire temperature formula and surface color determination, and describes the characteristics of various properties of reinforced concrete structures subjected to high temperatures.The rebound-residual bearing capacity comprehensive calculation provides a feasible method for the rapid calculation of bridge bearing capacity. This will provide a reference for the rapid and effective evaluation and reinforcement of similar bridges in the future.
