Situ Concrete - an overview | ScienceDirect Topics

Unlike precast units, in situ concrete is poured in its permanent location (Fig. 5.16) and offers a much more robust solution.If constructing a wall, for example, its reinforcing bars are assembled first, then shuttering or formwork erected around them and finally concrete poured into whatever space remains.

Connections in Precast Concrete Elements | Scientific.Net

The structural integrity of precast concrete structures depends mainly on the connections between the precast structural elements. The purpose of a connection is to transfer loads, restrain movement, and/or to provide stability to a component or an entire structure. Therefore, the design of connections is one of the most important aspects in the design of precast concrete structures.
