Experiment Study on Static Mechanical Behavior of Plain Steel Plate-Light Weight Concrete Hollow Composite Decks

Abstract

Steel plate-light weight concrete hollow composite deck was a type of novel composite deck which composed of steel plate, perforbond ribs connectors (PBL connectors) and light weight concrete and steel pipe. In order to understand the hollow composite decks mechanical performance, Static experiments of five specimens of this hollow composite slabs were conducted, among which two specimens were composed with longitudinal steel pipes and three specimens were composed with transversal steel pipe, with the aim to study the difference of the mechanical behaviors of the composite decks at the two orthogonal directions. Based on the experiment results, the effects of the direction of steel pips and the nominal shear-span of the slabs on the composite decks mechanical performance were especially studied. During the experiment process, the failure modes, strains of concrete and steel plate, cracking type, slippage of interface and the bearing capacity of the decks were studied in detail. From the experimental study, it could be found that there were no slippage between the steel plate and concrete were measured at the composite bridge decks, and the composite bridge decks showed high flexural rigidity, good ductility as well as better bearing capacity with the strength of bottom steel plate and top concrete both fully utilized. Therefore, it could be concluded that this type of composite bridge decks have good advantages at mechanical behaviors.

Mechanical performance test and analysis of prestressed lightweight aggregate concrete hollow slab

“…The specific results are shown in Table 9. The symbolic meanings in the formula can be referenced from Yang et al (2010)…”

“…The specific results are shown in Table 9. The symbolic meanings in the formula can be referenced from Yang et al (2010) X Table 9 shows that the test values of the bearing capacity of the prestressed lightweight aggregate concrete hollow slab differ only slightly from the calculated values. The test results of ordinary concrete hollow slab are slightly higher than the calculated values; however, the deviation remains approximately 6.2%, which is in good agreement.…”

“…In recent years, scholars worldwide have conducted much research on prestressed concrete hollow slabs and achieved outstanding achievements (Han et al 2018; Liu et al 2000; Yang et al 2008; Zhao et al 2004). Yang et al (2010) studied the mechanical performance of steel plate – lightweight aggregate concrete hollow composite slabs and presented research results that showed that the steel pipe in the hollow slab can significantly improve its bearing capacity and anti-deformation performance. Xu et al (2013) showed that the refractoriness of prestressed concrete hollow slabs at different load-holding levels gradually increases with decreasing load-holding level.…”

Experimental Investigation on Out‐of‐Plane Flexural and Shear Performance of Half Steel‐Concrete Slabs

“…ey were firstly used in CAP1400 NPP [3] and HTR-PM NPP [4] in Rongcheng, Shandong. More recently, they have been used in high-rise buildings as floor panels [5] and bridges as deck panels [6].…”

Contribution of perforated steel ribs to load-carrying capacities of steel and concrete composite slabs under negative bending

“…Ellobody (2017) developed three-dimensional finite element models for the SCC slabs proposed by Kim and Jeong (2006) and discussed the design method for composite bridges with SCC slabs. Yang et al (2009, 2016) studied the structural behavior of SCC bridge deck slabs with perforated rib shear connectors. Static loading tests on eight specimens were carried out.…”
