This study focuses on the compressive behavior and energy absorption performance of the multi-layer lattice-web reinforced composite cylinders under quasi-static lateral compression. The effects of the lattice-web layout and ceramsite filler on the failure modes, crushing response and energy absorption performance were investigated and analyzed.
shear capacity of FRP-reinforced beams was smaller than that of beams with steel stirrups. The effect of all considered variables on the web-crushing strength of FRP-reinforced beams is presented.
The effect of axial impact on thin-walled circular tubes, which are reinforced externally by a glass fibre reinforced plastic (FRP) composite, is studied in this paper. The influence of circumferential reinforcement on the static and dynamic crushing behaviour of steel tubes is examined.
Walls subjected to significant inelastic deformations and with strengths limited by concrete crushing of the web after flexural yielding are considered. It is shown that web …
An analytical model based on truss analogy is used to evaluate the experimental results and to obtain a design equation that predicts web crushing strength. Web crushing strengths of structural walk are predicted as a function of concrete …

The crushing walls of the central two honeycomb cells in Fig. 9(e) visually show the mutual contact behavior. At this stage, the compressive load in Fig. 8(a) increases rapidly with the compressive deformation, and the honeycombs would behave more like a dense solid material at the end of this stage.
The web crushing rules in EN 1992 are investigated by comparison with tests. Although they give significant increases compared with past practice, they appear to be largely valid within the range of tests. There are, however, some very …

The web crushing strengths of 16 reinforced and prestressed concrete I-beams are reported. The principal variables of the test specimens are the ratio of yield force in the prestressed steel to yield force in the nonprestressed steel and the area of vertical stirrups. The test strengths are compared with the upper limit on shear strength given ...

The web crushing rules in EN 1992 are investigated by comparison with tests. Although they give significant increases compared with past practice, they appear to be largely valid within the range of tests. There are, however, some very marginal values and some slightly below the safe ratio of tests to predictions of 1.0. These are all for cases where the 80% yield rule governs.

After the crushing test, results were compared with one another and the wrapped specimen. Finally, failure pattern, stress-strain curve, axial crushing strength, load vs deformation curve and ductility were found from the test results and also suggested the optimum usage of CFRP strips for SHS strengthening. ...

The crushing ratios from the simulation are depicted in Fig. 18, with the single crushing ratio (42.1 %) indicated by a red dashed line. The initial crushing ratio in the two-step process is 12.87 % lower than that of the single-step process, while the final crushing ratio is 21.93 % higher.
This paper reports the effect of pre-existing cracks on the web crushing strength of reinforced concrete beams. Two experimental series were conducted. The first series involved the test of four slender beams with large amounts of stirrups. The second series involved the test of five deep beams without transverse reinforcements. In both series, vertical pre-cracks were …
