Flexural behavior of precast concrete sandwich panels under different loading conditions such as punching and bending

Flexural Behaviour of Precast, Prestressed Ribbed RPC Bottom Panels

This study introduces a new type of precast, prestressed reactive powder concrete (RPC) bottom panel for a large-span composite slab. The bottom panels, which have one or two inverted ribs with openings, act as formwork during the construction stage. The paper experimentally investigated the crack characteristics, deflection, and normal section bearing capacity of four precast, prestressed ribb...

Failure design of high-rise concrete panels under fire loading

Flexural Behavior of Polyester Polymer Concrete Subjected to Different Chemicals

Polymer concrete (PC) is a composite material prepared by resin and aggregates. Advantages of polymer concretes include rapid curing at ambient temperatures, high flexural and compressive strengths, excellent chemical resistance and low permeability. In this research, a comparative study was performed on degradation of polyester resin concrete in different chemical solutions. Polymer concrete s...

Experimental Study on Flexural Behavior of Precast Concrete Shear Walls with Vertical Joint

Connections for Precast Concrete Load-bearing Shear Wall Panels

Precast load-bearing shear wall panels are used extensively for high-rise construction because of the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection '~md the overall integrity of the structure. This paper presents the results of a four-year research program conducted to i...
