2. The concrete structure has high compression capacity but lacks enough tensile bearing capacity, the bearing capacity is provided by arranging enough common steel bars, but the steel bars play a role and are necessarily accompanied by the cracking of the concrete, and the concrete can work with cracks for a long time, so the structural durability is influenced.
3. The traditional continuous beam bridge of the reinforced concrete composite beam generally adopts an open steel box for hoisting, and the torsional rigidity is low before the bridge deck slab is poured and installed, so that the design and construction requirements of roads and urban bridges with smaller flat curve radiuses cannot be met.
