The point of defensive wall spikes and defensive spikes?

[Thero]

What is the point of these two structures? They don't appear to hurt anyone. Do they add durability to the defensive wall? Or is it just another wall that looks different?

defensive wall spikes (the rock-stick thing right?) is used on defensive walls to add 40% more durability. The defensive spikes are another defensive wall that can be climbed (dunno why lol)
it's more effective as a combination of different walls or with traps such as deadfall

Pretty much exactly this.

Use traps not walls to block off entrances.

Thanks Maron. How does one know how much % it increases? Is it written down somewhere in the game?

But using walls is just wasting your time, first cowman will roll you.
