Dear Denise: I have two suggestions for dealing with the situation you describe. The first is to work with the chandelier designer on a system that is consistent with the design. The guy wires in your scheme could be replaced by chains matching those of the chandelier (if there are chains); these could even have crystal pendants and lights. Springs could be used to reduce impact effects, but the piece would still have to possess some strength. The second suggestion is to do a dynamic analysis of the structure and pendulum to make a better estimate of the required separation. A long pendulum is essentially base-isolated. The remaining question is whether its movement can be tolerated. In either case, the fragility of the chandelier is worrisome, given its location. If it is plaster, it might be possible to have reinforcing lath tied into the main support, so that if it does break apart, the major chunks will still be supported. Best of luck, Rafael Sabelli
