Abstract
In Germany, most of logistic halls are constructed with precast reinforced concrete members. Nowadays, there is an increasing demand for logistic halls where the roof construction is to realize with a span of up to 60 m without any inner support. However, the production and the transport of 60 m long precast concrete members are only to perform under extraordinary difficulties. Therefore, it was necessary to develop another solution. The idea was to produce two separate precast concrete segments and to transport them to the site. At the site the segments are combined to the final girder by prestressing them together, resulting in a segmental girder with the requested span of 60 m. The paper provides information about the structural demands on the joint between the two segments and the carried-out experimental program.
