首先，分析了型钢与混凝土之间的粘结机理，并与普通钢筋混凝土结构进行了比较。
At first, the bond mechanism between shape steel and concrete compared with that of normal reinforced concrete is analysed.
其中一榀模型为普通钢筋混凝土结构，另一榀模型在底部转换梁施加了预应力，并在底部转换梁及部分杆件采用了钢骨混凝土。
In which one of them was common reinforced concrete structure, and the other used prestressed steel reinforced concrete (PSRC) in bottom chord of the transfer structure.
普通的钢筋混凝土结构已经不能满足要求。
The ordinary structure of armored concrete can't already meet the demands.
然而和普通钢筋混凝土一样，预应力混凝土中存在的一个主要问题是钢筋抗腐蚀能力弱，结构耐久性差。
However, like general reinforcement concrete structure, a main problem in prestressed concrete is the poor corrosion resistance of steel tendon which may lead to the lower durability construction.
通常情况下，大幅度提高抗压强度混凝土用于预应力结构比普通钢筋混凝土建造的。
Ordinarily, concrete of substantially higher compressive strength is used for priestess's structures than for those constructed of ordinary reinforced concrete.
通常情况下，大幅度提高抗压强度混凝土用于预应力结构比普通钢筋混凝土建造的。
Ordinarily, concrete of substantially higher compressive strength is used for priestess's structures than for those constructed of ordinary reinforced concrete.
