Experimental Study for Structural Behaviour of Precast Lightweight Panel (PLP) Under Flexural Load

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...

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

Experimental study of the behaviour of building structural elements under soft impact

Dynamic three-point bend tests are performed on small beams specimen made of a quasi-brittle material. The most classical hypotheses needed to analyse the tests with SHPB, which are based on a state of quasi-static balance of the body, cannot be used. In order to get the behaviour it is necessary to perform a transient analysis of the specimen response. In most cases, the useful duration of the...

Structural behaviour of RC beams with external flexural and flexural–shear strengthening by FRP sheets

This paper presents experimental research on reinforced concrete (RC) beams with external flexural and flexural–shear strengthening by fibre reinforced polymer (FRP) sheets consisting of carbon FRP (CFRP) and glass FRP (GFRP). The work carried out has examined both the flexural and flexural–shear strengthening capacities of retrofitted RC beams and has indicated how different strengthening arra...

Experimental study of grouted sleeve lapping connector under tensile load

The performance of the grouted sleeve lapping connector that is used to connect reinforcement bars in a precast concrete structure is studied. A total of 63 specimens, varying in bar diameter and lap length, were tested under tensile load. The failure modes, ultimate tensile strength values and load-displacement curves of the specimens are discussed in the study. Two equations are proposed for ...
