I have a flight of steps leading up to a building but the steps and the building are on two different (joining) sims and half the people using the steps dissappear through the floor as if it is a phantom.

Are there any tips or workarounds that people can offer me to get over this?

Put a prim (maybe coated with invisibility texture), which has its center in the other sim. just beneath your staircase.

The trick to making any surface that crosses a sim border is to have overlapping prims that are rooted on both sides. That is because as far as each sim is concerned, prims sticking into it from the other side are phantom, and there is a hand-off phase where you can easily fall through when you cross the edge, if you don't take that into account.

Let's say you are doing a simple one prim wide hallway floor, spanning a sim break. It has one prim that splits the sim border halfway, and that prim is linked to a linkset of prims with the root in sim A.

In sim B, the floor continues where the other prims left off. But there is an 'extra' prim, which can be invisible, that is occupying the exact same space as the one sticking over from sim A. This extra prim is linked to one or more prims whose root prim is in sim B.

One trick : You can't link a prim to a prim in the next sim over... So, what you do is position the prim in sim B, slide it across the border to sim A, link it to the linkset in sim A, and then edit linked objects to slide the linked prim back over into the other sim. This will eliminate problems with prims that refuse to link becaus etheir center is just over the line from the side you need to link it to.

The main thing is that from both sides, the simulator needs to believe there is still a surface to step onto when you step over the border.

Right.
And it helps to have as MUCH prim projecting into the new sim as possible, thereby giving the traveling avitar a LOT of old PRIM to walk on as he enters the new SIM.

so, try applying a lot of TOP SHEAR to a 10x10 cube.Flatten the cube right out. This will give you a long runway of almost 10m on either sim from a single prim.
