“…(4) The local effect of bond deterioration near the cracks has a significant influence on the global stiffness of the RC element. In the present study, it has been shown that the decreasing stiffness of the specimens using the stress transfer algorithm can be simulated by the so-called damage zone model (see (5)).…”

“…This may be attributed to the fact that the theoretical models do not take into account progressive formation of splitting cracks causing deterioration of bond at high strain levels. This can be taken into account by the stress transfer approach using the damage zone model (see (5)). As can be seen from the normalized tension stiffening diagrams (Figure 8(b)), the simulated average force in concrete decreased with increasing strain and it was also characteristic of the experimental curves.…”

“…To evaluate the influence of bond deterioration on the deformation behaviour of the tested specimens, the developed stress transfer algorithm was adopted with and without the damage zone (see (5)). Due to the random formation of cracks, the load-average strain diagram was simulated 5 times repeatedly for each case to better represent the deformation behaviour.…”

“…Due to increasing demand of high-performance materials for structural applications, a number of investigations have been carried out in the last decades concerning the use of high-strength reinforcement. Most of the research studies were dedicated to the analysis of the ultimate limit states: shear strength of large concrete beams [2], bond characteristics of lapped splices [3,4], and load bearing capacity of flexural members and bridge decks [5,6].…”

The increasing application of high-performance materials in civil engineering led to the development of reinforced concrete (RC) structures with reduced cross sections and increased spans. In such structures serviceability limit state often becomes the governing condition of the design. Present study investigates the deformation behaviour of high-strength RC ties reinforced with high-grade bars. Experimental investigation was carried out measuring the postcracking stiffness of the specimens at high strain levels. It was found that, despite the reduction in stiffness, a considerable part of the average tensile stresses were carried by the concrete at the advanced loading stages, thus effectively stiffening the RC member.

“…When a structure meets these requirements, the design of B-regions is considered feasible, which means that the values of the structural geometric dimensions and materials are acceptable [24]. The conventional analytical calculation procedure for the design based on the LRFD method is illustrated in Figure 2 [23,25,26].…”

Unified Flexural Resistance Design Method and Evaluation Frame for the B-Regions of RC Flexural Members—Theory and Application

The load and resistance factor design (LRFD) method is normally used to design B-regions of reinforced concrete (RC) flexural members. The design includes many checks corresponding to different limit states. The LRFD method requires many loop calculation steps in the design, demonstrating its relative inefficiency. It cannot be applied to compare limit states directly and quantitatively. Different design limit states are separated and isolated. How to improve the analytical calculation efficiency of the LRFD method and to realize direct and quantitative comparisons between limit states are very important problems in structural engineering. This paper presents an innovative unified flexural resistance design (UFRD) method and a unified flexural resistance evaluation (UFRE) frame to solve these problems to some extent. The main contents include the unified flexural resistance (UFR) principles, formulas for the unified flexural resistance design (UFRD) method, the operation procedure to facilitate its usage, the UFRE framework to compare limit states, and three examples. The results show that the UFRD method can provide the same design outcomes as the LRFD one. However, UFRD calculations are simpler, requiring at most 20% of the calculation steps of the LRFD method. The UFRE frame can make different limit states compare with each other directly and quantitatively, which cannot be realized by the LRFD method. It helps expose some potential and insufficient flexural resistance hazards for some limit states, such as the only 10% relative strength reservation of one example. Thus, the UFRD method and the UFRE frame supplement and develop the LRFD method to some degree. The simplicity and practicality of the approach and the frame make them appropriate for many applications.
