The efficiency of precast concrete frames in resisting gravity and lateral loads relies on the behaviour. of beam column connections. Beam-column connections should be designed to transfer all forces. connection, steel billet connection, single cleat connection, and double cleat connection.
precast concrete beam-to-column connections. Knowing that most of precast connections. The M-φ curves of the monolithic and precast connections obtained from the tests are. shown in Figure 8. The maximum moment resistance achieved by the monolithic. connection, CF-RC was 5. 4 kNm. While for the precast beam-to-column connection, CF-. PC, the ultimate moment resistance was 5. kNm, about 11 % higher than the monolithic. The ultimate moment resistance of the connections can also be compared with the.

To identify the mechanisms of the bearing and failure of steel bars embedded in concrete subjected to transverse load, static loading tests using 24 concrete blocks containing dowel bars, bolted platemounted bars, or welded studs were conducted. The behavior up to failure is examined based on the results obtained from the tests and analysis using the traditional beam on elastic foundation (BEF) analogy.
Precast concrete (PC) beam-column connections using ductile rods are . This paper is a companion to the largely non-technical article that was recently published in the September-October 1994 PCI JOURNAL.
Precast concrete (PC) beam-column connections using ductile rods are proposed for earthquake zone. An existing beam-column connection, two PC specimens designed by considering failure modes and a conventional RC specimen were tested under cyclic loading to evaluate the seismic performance. The specimens were designed to satisfy the requirements of current design code. Tests on an improved beam column connection for precast concrete.

An unbonded post-tensioned precast concrete beam-column connection is constructed by post-tensioning the beam to the column using strands or bars that are not bonded to the concrete. The clamping force between the beam and the column provides vertical shear force transfer at the interface between the beam and the column, so a corbel is not needed. The CFT (Concrete Filled steel Tubes) column-footing connection is cast-in-place embedded type which provides simple construction procedure, low cost, and superior structural performance.
Precast concrete is a form of concrete that is prepared, cast and cured . Concrete is cast into forms and left to cure. It is important therefore, that they are properly designed and embedded in the concrete.
Precast concrete is a form of concrete that is prepared, cast and cured off-site, usually in a controlled factory environment, using reusable moulds. Precast concrete elements can be joined to other elements to form a complete structure. Precast forms are normally made of steel or plywood. Whereas plywood forms are usually limited to about 20-50 castings depending upon the complexity of the form, a virtually unlimited number of castings can be made by precasting using steel forms.

Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength.
Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets.

Three additional typical reinforced concrete beams of the same total dimensions were also cast to serve as control specimens. Two types of single-layer and double-layers steel meshes were used to reinforce the permanent U-shaped forms; namely welded wire mesh and X8 expanded steel mesh. Three types of core materials were investigated: conventional concrete, autoclaved aerated lightweight concrete brick, and recycled concrete
