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.
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 effect of sustained uniaxial compressive load on the permeability of concrete was studied by a load-permeation testing device with pressed spring loads.
