過大的變形容易導致護欄承受出現(xiàn)除車輛碰撞力以外的其他荷載類型。

Excessive deformation will easily lead to other load types except vehicle collision force.

使受力變得更為復雜。

Make the force more complicated.

而鋼護欄一般較砼護欄柔一些。

The steel guardrail is generally more flexible than the concrete guardrail.

若需要兩者受碰撞后的變形一致，則鋼護欄需要更大的剛度。

If it is necessary to have the same deformation after collision, the steel guardrail needs more stiffness.

對鋼護欄材料也相應較高。

The material of steel guardrail is also relatively high.
