Abstract:

The channel steel connectors of novel prefabricated prestressed concrete beam play an extremely important role in structures. They act as the connectors of prefabricated beams and columns and support the prefabricated beams temporarily at construction stage, work as shear connectors of the adjoining faces between the old and new concrete at using stage. But they are easy to be bond slip failure for its complicated stress states. To analyze their mechanical behavior and failure mode, the interaction between concrete and channel steels is considered by adopting the spring unit and nonlinear anal

Abstract This paper aims to study the effect of reinforcement configuration (steel fibre and rebar) on the mechanical performance of composite slabs of the same total steel contents. We manufactured four pieces of fullscale multi-ribbed composite prefabricated slabs with different reinforcement configurations by using steel fibrereinforced concrete, foam concrete, and normal concrete. The multi-ribbed composite prefabricated slab has many excellent properties, such as light weight, good thermal and sound insulation. Thus, it can be applied to fabricated structures.

Abstract:

Prefabricated construction is an emerging industry in Australia and considered a key mechanism to boost productivity in the construction industry. The use of fibre reinforced concrete has a huge potential in the prefabricated industry as the concrete can be delivered straight to the precast mould, eliminating in many cases the steel reinforcement, thus increasing production quotas and cost savings. Such results can be further improved by utilising self-compacting concrete reinforced with fibres. Although the use of steel fibres as reinforcement is now well established, in the precast industry

Abstract:

Conventional construction methods of reinforced concrete (RC) structures generally require a long construction period and high costs due to many on-site temporary form works. In this study, a prefabricated permanent thin-walled steel form integrated with reinforcement cage (PPSFRC) was developed, and it makes for a fast-built construction by reducing the temporary form works. Axial compression tests were conducted on a total of 9 test specimens to investigate the structural performances of the newly developed columns. The proposed column construction method utilized relatively thinner steel pl

In this study, 6 prefabricated reinforced concrete columns with different lengths of connectors and thicknesses of the steel plate used in connectors and 1 cast-in-place reinforced concrete column were made, and then these specimens were tested under the low cycled reversed loading experiment to study the seismic performance of the prefabricated reinforced concrete columns with steel mortise and tenon connections. The failure mode, bearing capacity, ductility, stiffness degradation, and energy dissipation of the specimens were analyzed. The results show that compared with the cast-in-place spe

Based on the monotonic tensile test of grouted sleeve specimens conducted, this paper uses multifactor regression analysis to construct the equivalent constitutive relationship of grouted sleeve specimens under uniaxial tension. The study based on this constitutive relationship of grouted sleeves and the effect of bond and slip between steel and concrete were considered. The prefabricated reinforced concreted beam-column joints with grouted sleeves were presented with finite element software ABAQUS.

Four rebar constructional forms were conceived to compare the ability of transferring tension force between two slabs. Symmetric two-points monotonic static load test were performed to attain their flexural performance. The test results indicates: the prefabricated RC sl

Abstract:

Applications of high-strength steel products in civil engineering have been limited by elastic local buckling, by the perceived lack of ductility, and by the perceived difficulties of welding such steels. This article proposes a new column (i.e. high-strength steel plate–concrete-filled fiber-reinforced polymer tube) consisting of an outer fiber-reinforced polymer tube, concrete infill, and encased high-strength steel plates that are connected to each other by bolted angle brackets at discrete elevations. The column offers an ideal opportunity for the use of high-strength steel plates in const

Quasi-static tests of three specimens of steel-concrete composite fabricated shear wall were performed to investigate its seismic behavior. The test results indicate that horizontal cracks run through the interface between the wall and the base beam, diagonal cracks appear on the whole prefabricated concrete shear wall. The specimens fail in the mode of bending-shear, the hysteretic curves according to the test were full, it means that they have better seismic bearing capacity.

The high-strength bolt shear connector in prefabricated concrete slab has advantages in applications as it reduces time during the construction of steel-concrete composite building structures and bridges. In this research, an innovative and advanced bolt shear connector in steel-concrete composite structures is proposed. To investigate the fundamental mechanical behavior and the damage form, 22 static push-off tests were conducted with consideration of different bolt dimensions, the reserved hole constraint condition, and the dimension of slab holes.

Abstract:

This paper reports the results of an experimental campaign conducted on a set of eight composite beams made of prefabricated steel trusses encased in structural concrete. The test setup is organized in such a way to apply an evenly distributed load on the beam, so to simulate the actual loading condition in real buildings. This is also to avoid the formation of peculiar and unusual shear resisting mechanisms occurring in three or four-point bending tests. The experimental results are presented in terms of force-displacement graphs and also in terms of stress-strain diagrams in the steel member

The use of prefabricated mini silo structures enables us to build containers for grain or animal feed and to transport the structural elements to the installation site. Traditional types of strengthening of concrete structures are steel and concrete cages. Polymer materials are widely used in construction. The methods of strengthening modern materials, such as lamellae, are being increasingly used. The issue of strengthening the structures with composite polymer materials is relevant.
