POTENTIAL FOR THE INCLUSION OF SUSTAINABILITY ASPECTS IN LIMIT STATES FOR CONCRETE

Hrabova, K.; Vorechovska, D.; Teply, B.
Abstract:
The structural design of concrete structures needs to result in qualities ensuring structural safety and serviceability, together with durability, robustness, sustainability and resilience. Due to this, the effects of mechanical load, environmental load and even social coherence need to be reflected and included in the formulation of limit states. This is a complex matter involving the time factor, service life, degradation effects, modelling, probability analyses, limit states, costs and other phenomena, and it is not yet completely understood. Currently, concrete structure design is required to be performance-based according to fib Model Code 2010, and newly attention is being paid to sustainability issues. Sustainable target value design can be briefly expressed as the comparison of sustainable capacity vs. sustainable impacts, forming a new class of limit states – sustainability limit states. The intended contribution will discuss such limit state variants, their context and formulation. This paper provides an overview of limit states for reinforced concrete structures, and their consequences. For the presentation of the proposed sustainability limit states an experimental and numerical investigation was performed on an RC beam kept in a long-term loading state (three point bending) with chloride influence.
