Deterioration of Reinforced Concrete Structure made an alarming situation for researchers and students for specializing in the sturdiness affecting parameters along side crushing strength, various uncontrollable parameters like environmental or exposure situations are equally important for the service existence of structures. Rusting of reinforcement in strengthened concrete diminishes the provider existence and exacerbates concrete structures causing early stage failure of structures. Therefore, assessing present situation of reinforced concrete structure is essential for planning, repairing and replacing of structure.

Load Carrying

Load-carrying system of reinforced concrete structure on construction is different from load-carrying system on service life. This temporary load-carrying system is composed of shores and concrete members of early age on construction. Geometrical model and material property of structure are time-varying on construction. Through secondary development of ANSYS, the processes of placing concrete and removing shore are simulated on construction. Critical effect factors are determined through the analysis on mechanical property of temporary load-carrying system, such as shore stiffness, foundation stiffness and diurnal temperature difference. Results of analog calculation to temporary load-carrying system will provide basis for shoring system design and structure reliability analysis on construction.

Impact Simulations

The understanding and assessment of accidental crash scenarios on reinforced concrete structures is of high interest for safety issues. Although experimental research on this topic has already a long and successful history, there are many issues waiting to be solved as far as numerical simulations are concerned. In this article some particularities of the Abaqus Concrete Damaged Plasticity (CDP) model are investigated with the purpose of using efficiently the CDP model in impact loaded reinforced concrete structure simulations. In particular, the sensitivity of the simulation response with respect to model parameters and element size is studied. The simulation response is compared to measurements from benchmark impact tests on reinforced concrete plates.

The Impact

The corrosion of steel will have a bad impact on the safety of reinforced concrete structure. In severe cases, it may even be disastrous. In order to understand the impact of steel corrosion on the structure, tests are carried out to study corrosion and expansion rules of steel bars as well as the impact rules of corrosion on bond force between steel and concrete. The results show that wet and salty environment will result in steel corrosion; relatively minor corrosion will not cause expansion cracks of protection layers; when steel rust to a certain extent, it will cause cracks along the protection layer; when there exists minor corrosion in steel and the protection layer does not have expansion cracks, the bond force is still large and rapidly decreases as the corrosion rate increases.

Complex Construction

<p>The curing of concrete is extremely important for the durability of a reinforced concrete structure. In practice, due to the complex construction processes, the very limited phases and the lack of control, aftertreatment is often neglected by executing companies. Hence infrastructure operators are therefore very interested in having a robust, simple tool that enables aftertreatment to be easily checked and, as a result, to convey the importance of this process step to the client. In the project presented here, classic and novel test methods are presented and discussed, as well as their suitability for the detection of the aftertreatment quality on laboratory samples and subsequently on some real structures.</p>
