4, 受压翼缘(compression flange )越大,对截面受弯越有利(x减小,内力臂增大) 5, 但试验和理论分析均表明,整个受压翼缘混凝土的压应力增长并不是同步的.

翼缘宽度变化按加强受压翼缘和加强受拉翼缘考虑。
Flange width has changed by strengthening the compression flange and strengthening the tensile flange.
受压翼缘混凝土板的应力随着时间的增加而减小，但减小的幅度随剪力连接件的刚度增加而减小。
The concrete slab stress of the pressed flange decreases with the increment of time. But the diminished stress value decreases with the increment of the shear connector rigidity.
