The arch: shear stress

The arch support itself by shear stress. In other words: every layer of crates is carried by the next layer. This is due to the fact that the crates are interlocked with each other. This is a crucial factor for the design of the bridge, because it is a key factor for a functioning bridge. Therefore, a lot of research about the properties of the crates have been done besides the research many tests in the lab were executed which are described under the heading preparation. After the calculations of the design it appeared that in every cross section are sufficient crates which can bear its own weight.
