---------------------- multipart/alternative attachment Jack, I have no experience with falling pianos, but I was involved, in a previous life, with designing a structure to pass California's earthquake-proof building codes. It's been a while, but my recollection is that the most significant load is the side-to-side motion, so it seems plausible that a piano could be tipped over. Also, we had to hire an engineering firm, licensed in the state of California, who analyzed and approved our design. You should separate yourself from any design responsibility here. If the church has gotten some engineering authority to say " if you chain it this way, it will be safe", then go ahead and chain it exactly the way they tell you to. just my 2 cents Mike Spalding RPT ----- Original Message ----- From: Jack Houweling To: Pianotech Sent: 6/28/2003 12:57:30 AM Subject: Earthquake proof Hello I got a call from a church yesterday . They have an upright piano that is in the play school and want to earthquake proof the piano with hooks and chains to the back of the piano. Has anyone ever heard of a piano falling? Should this be of any concern? I live in Vancouver B.C. ( We are expecting the big one.) Jack ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
