Exploding Launchpad: The S1 SRB is unstable!

[Brainlord Mesomorph]

Building a huge liquid fuel rocket. Stands on the launchpad fine.

add 2 S1 SRBs (not even near the ground) and KABOOM!

remove the SRBs - all's quiet

put them back - KABOOM!

add launch clamps to the SRBs, ... no kaboom.

Launch clamps hold your rocket up, so no boom, for even less boom try putting some structural panels under the engines, they can surface attach to the launch clamps

I know what launch clamps do. My point is you only seem to need them if you add S1-SRBs.

Mkay... so is this actually a question? Doesn't really look like a question.

If not, do you have any screenshots to explain what you're talking about?

Edit: As far as I've experimented, tho, it doesn't matter if you attach the launch clamps to the SRBs or the central rocket. (At least on my designs, I have no idea what you're working with.) The only time I've had an issue with it exploding the launch pad is when I had the bottom on the SRBs clipping through the floor in the VAB. As long as there's some clearance there, you shouldn't have any problem with an exploding launchpad.

To answer the "question." If it is a question.

Isn't this just because you've added some weight to your rocket and crossed whatever threshold destroys the pad?

Using your logic:

10-ton trucks are explosive!

I can stand on the ground, no problem.

Place just one 10-ton truck on my head, and it smashes violently to the ground!

Obviously this means that there is something wrong with the truck!

You *do* realize that those S1 boosters weigh 48 thousand pounds. each?

You might be simply increasing the pressure footprint of your vehicle too much.

Also, the S1 is a loooong skinny tube. It might be swiveling around its attachment point. Try adding a strut?
