Cyclic Loading Tests

The problem of environmental pollution and waste concrete generation will be alleviated if concrete structures can be designed with both recycling and reuse strategies. In this regard, this study employed recycled coarse aggregate as the structural material in a novel beam-column joint with Design for Deconstruction (DfD) connections. Two series cyclic loading tests including pre-loading and re-loading on this frame joint was undertaken and the effect of recycled aggregate concrete (RAC) on structural behaviors was carefully evaluated. It is demonstrated that the DfD joint with RAC had favorable integrity and the influence of RAC was acceptable for practical application. Furthermore, the shear force model of the joint core area for RAC beam-column joint with DfD connections was put forward in this study, which showed good agreements with experimental results. Life cycle assessment (LCA) indicated that the carbon emission of the beam-column joint with DfD connections made of RAC increased at construction process but would reduce the total carbon emission from the perspective of lifetime.

Push Out

Investigation of the load transfer of concrete plugs to tubular steel piles subjected to tension and compression and cyclic loading has been conducted at Monash University over the past 3 years. The work presented in this paper reports on the results of the combination of pull-out, push-out, and cyclic loading tests carried out on 15 steel tube specimens filled partially with reinforced concrete with variable lengths of embedment. The pull-out force was applied through steel reinforcing bars embedded in the concrete plug, and push-out forces were applied through a thick top circular plate on the top of the concrete plug. Test results included the cyclic loading, ultimate pull-out and push-out forces, slip of concrete plugs, and longitudinal and hoop strains along the piles for some specimens. The tests clearly showed that average bond strength significantly exceeds expectations and is higher than the results of previous investigations using plugs without reinforcement. The test results also indicated that cyclic loading tests reduced the bond strength due to the accumulation of damage to the plug–pile interface. The push-out and pull-out tests conducted under symmetric cyclic loading demonstrated that slip between the concrete plug and the steel tube increased with repeated loading, and the rate of slip growth increased with an increase in the peak load.Key words: tubular steel pile, reinforced concrete plug, bond, cyclic loading.

Cyclic Loading Tests

In order to verify the feasibility of a new overallseismic reinforcement method of the framework. Firstly，carried low cyclic loading tests on reinforcedconcrete framework, then reinforced the framework with a new method, and repeatthe low cyclic loading tests , finally, compared and analyzed the data from twotests. Compared with the original framework, the shape of the hysteresis curveis more full and the skeleton curve of the parallel period is longer andthe ductility factor increased by 35% and the bearing capacity increased by 40%.The results show that reinforcement framework has better energy dissipationcapacity, ductility and transgender capacity.
