“…Deng [12] investigated the variation of the critical load of local buckling of the web of I-beams with different hole-height ratios and number of holes, with and without transverse stiffening ribs and with and without web openings. On the basis of this, Serror [13] The truss steel composited plate is a prefabricated steel truss formed by welding the lower part of the bent steel bars with the upper and lower longitudinal bars in the slab in the laminated layer and then tied to the upper layer of the reinforcing steel and cast-in-place concrete to form a concrete slab with overall stress [22]. Many webs of truss reinforcement are interspersed in the laminated layer and the cast-in-place layer, which facilitates a tight connection between the two layers of concrete.…”

“…Sci. 2023,13, 7028 12 of 36 intersection direction began to appear at the interface between the concrete laminated layer and the cast-in-place layer, but they were not continuous, and most of them started to develop at the end of the crack at the bottom of the composited plate. When the load reaches 180 kN, the crack at the bottom of the slab continues to develop upward, crossing the interface between the laminated layer and the cast-in-place layer and developing toward the cast-in-place layer.…”

However, the transverse crack at the interface between the composited plate and the cast-in-place layer did not develop significantly compared with that at 130 kN and did not penetrate along the interface, indicating that the laminated layer and the cast-in-place layer were still closely combined and jointly stressed.…”

The tightly spliced truss-reinforced plate-honeycomb flat beam is a novel type of composite beam, with the advantages of high rigidity, high bearing capacity, and ease of construction. In this study, on the basis of the performance in bending tests, the numerical analysis method is used to study the influence of the honeycomb hole–height ratio, and section height on the bearing capacity of the honeycomb composite flat beam. On this basis, the simplified method to calculate the ultimate bending capacity of the new honeycomb composite flat beam was proposed. The research results show the failure modes of the specimens are mainly divided into two states, including the deflection exceeding the limit and the concrete flange plate separating from the steel beam. The tightly spliced truss-reinforced plate-honeycomb flat beams have good ductility, of which the average value reaches 8.2. The simplified method proposed in this article for calculating this type of honeycomb composite beam has an error of less than 10% in terms of bending bearing capacity, which has advantages over the double T-shaped steel method. The calculation method and design suggestions proposed in this study provide a basis for the research and application of this type of composite flat beam.

“…[8][9][10] studied the shear bearing capacity of honeycomb beams under different conditions and reported that the shear bearing capacity of the beams is greatly affected by flange thickness, opening ratio, and pass type; they also proposed a simplified formula for calculating shear bearing capacity and presented a correlation between bending and shear. Some other relevant works in this context can also be found elsewhere [11][12][13].…”

Experimental Study and Theoretical Analysis on Seismic Performance of Castellated Beam With Hexagonal Holes

2020

Under a reciprocating load, through an experimental study and finite element analysis, the effect of different arrangements of stiffening ribs on the failure mode, local stability, and hysteretic performance of castellated beams with hexagonal holes is investigated. The test specimens comprise four steel castellated beams, two of which are reinforced with transverse stiffening ribs having the same opening rate but different height-to-thickness ratios of the webs; the two other steel castellated beams do not have any stiffening ribs. The results show that the steel castellated beams with a high height-to-thickness ratio are prone to local buckling failure of the webs. When, under a low-cycle reciprocating load, the transverse stiffening ribs are arranged, and the steel castellated girder is constrained by the plane, the failure mainly occurs at the hole angle position, and the hysteretic performance of the steel castellated girder is obviously improved compared with the non-stiffened steel castellated beam. Using finite element analysis, w e realize that different arrangements of transverse stiffening ribs change the failure mode of the steel castellated beam and that the reasonable arrangement of the stiffening ribs has a significant influence on the hysteretic performance of the castellate d beam.
