Precast Concrete Shells a Structural Challenge

UHPC is very similar to that of standard precast concrete production. Joining precast elements using mechanical screwing systems and press-fitting the contact surfaces is extremely effective when compared to conventional methods of filling the joints with in-situ concrete. It also creates a new and different feeling for concrete structures.

3 ways to connect precast columns to foundation - choose

Bolted connection. As its name implies, a bolted column connection is made with anchor bolts. Cast into the foundation using a template, the anchor bolts transfer tension, compression and shear forces to the reinforced concrete base structure. The bolt counterparts - column shoes - are cast in to the columns at a precast factory.

Precast concrete bridge systems optimization - Morgan

Stay-in-place deck slab forms or full depth deck slab panels are used to achieve rapid construction, improve safety and reduce the cost of the deck slab removal. In order to increase precast concrete I-girder spans while minimizing the superstructure depth, four different systems for creating continuous spliced concrete I-girders are presented.

An Economical and Efficient Foundation ... - Share research

For example, the CFT pier shown in Figure 1 will have comparable resistance to a larger reinforced concrete pier, but will have 27% lighter weight, correspondingly less material, and smaller mass. This occurs because CFT places the reinforcement at the optimum location, and the concrete is better confined to reduce damage due to concrete spalling.

Precast Concrete Construction Technologies for Metro

Given the character of the Metro projects, the use of Precast Concrete technologies is the obvious answer. In the urban situation, pre-casting of the concrete elements is usually carried out in an 'away' casting yard and limiting the dimensions and weights of the individual precast elements become important considerations in design.
