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.

钢构件安装精度控制、钢筋绑扎及混凝土浇筑是钢骨混凝土结构质量保证的关键。

And steel member placement, steel bar tying, concrete casting is critical to the quality of steel skeleton concrete structure.

计算表明，钢骨混凝土柱的轴压比限值一般比钢筋混凝土柱的高(25 ~ 50)%。

The calculated results show that the limit values of axial compression ratio of SRC columns are generally (25-50) % higher than those of RC columns.
