Carl asked me to forward this. From this, Gaudi seems to have been pushing the structural capabilities of his materials, but carefully. One might keep the "carefully" in mind when falling in love with arches, vaults, the flying aspect of buttresses, even flowerpots on the tops of columns. The article is pretty interesting--talking about recreating historic, no longer extant buildings digitally with software that was not exactly designed for the purpose--it might even be animation software. And I left the link in to a--famous--structural engineering for kids book. ........................................ From: carl <carl at cgpl.org (snipped a bit): Yes simple hanging weights on strings in the case of Goudi, but its the knowledge to know how to use. Goudi had samples crushed under hydraulic pressure so he would know exactly how much psi the columns he made would hold. Strings in tension model the compression. compression and tension are in some way the same... you can not have compression with out tension. In "all" compressive buildings the tension is expressed by the forces inside the stone / building block ie.... when will they explode or split under pressure how much pressure. So the method of strings and weights is simple, but its the knowledge of how to use it that is not so simple. In a book for kids the relationship between and compression and tension forces are demonstrated by the chains and weights. Only Goudi knew how to use them and the cost of his buildings were very high and they took a long time to build ( limited by the number of skilled craftsmen that can physical work on the critical path structures ) was in all the labor to put the right amount of material in the exactly the right place within an 1/8 of an inch would be my guess. The craftsmen worked from the string models. So many times Goudi would in the middle of his construction ( looked like it could be finish by others who would work faster ) would be fired.... and he would be force to take his craftsmen and his string model with him.... The construction would continue at much faster pace .... with out his guidance and then collapse during or just after completion killing many workman...... Then it would be said that it was Goudi's fault. I am a sculptor and the planed masters work of my life is the automation so to speak of Goudi using natural building materials.
