Abstract
Shell stuructures are very excellent system from the point of view of material efficiency. On the other hand, the construction process requires a great deal of time. It is a reason that shell structures have declined since the latter half of the twentieth century. Heinz Isler, a Swiss engineer, developed form finding methods from experimental studies using suspended surface and he had realized large amout of shell structures since 1970s. But its construction system is not very different from normal shell construction process. Therefore, it is difficult to apply his methods to the present time. In this paper, an easy construction method for Isler-type shell structures is proposed. The main points of this system is to make a rigid suspended surface directly by making use of hanging net. In this system, it is fully feasible to realize small-scale shell structures with a span of 10-15m without any formwork.
