使受力变得更为复杂。
Make the force more complicated.
而钢护栏一般较砼护栏柔一些，若需要两者受碰撞后的变形一致。
The steel guardrail is generally more flexible than the concrete guardrail, and the deformation of the two guardrails after collision is consistent if necessary.
则钢护栏需要更大的刚度，对钢护栏材料也相应较高。
Therefore, the steel guardrail needs more stiffness, and the material of steel guardrail is also relatively high.
