An analytical model for reinforced concrete columns with

Given that the biaxial hysteretic model of shear-critical reinforced concrete columns is usually developed by incorporating with the single-degree-of-freedom system to write its expression in differential equation of motion control, it is unfeasible to match with the experimental data of the biaxial quasi-static testing in terms of force-displacement relationship.

parameters, the model is effective in predicting the nonlinear flexural response of slender reinforced concrete walls. ANALYTICAL MODEL The model in Fig. 2(a) is an implementation of the generic two-dimensional MVLEM wall element. A structural wall is modeled as a stack of m MVLEM elements, which are placed on one another (Fig. 2(b)).

Compressive arch action (CAA) is a favourable structural mechanism to mitigate progressive collapse of reinforced concrete (RC) frames. To quickly and accurately predict the CAA capacity of RC sub-assemblages under a column-missing scenario, an engineering analytical model is proposed.

reinforced concrete beams. Firstly, literature review was conducted to evaluate previous experimental and analytical procedures related to reinforced concrete components. Secondly, a calibration model using a commercial finite element analysis package (ANSYS, SAS 2005) was set

2001) developed an analytical model to study the behavior of slender FRP-RC columns. The model was verified with steel-RC columns from the literature. Mirmiran et al. (2001) recommended reducing the slenderness limit of 22 for steel-RC columns to 17 for FRP-RC columns with a reinforcement ratio of 1%.

Figure 1.1 shows the behavior of a steel tubular column, a reinforced concrete (RC) stub column and a concrete filled steel tubular stub column without reinforcing bars. As it can be observed, the summation of the steel tube and the RC columns ultimate strength is less than that achieved by the CFST column Han et al. 2014.

Column shear failures observed during recent earthquakes and experimental data indicate that shear deformations are typically associated with the amount of transverse reinforcement, column aspect ratio, axial load, and a few other parameters. It was shown that in some columns shear displacements can be significantly large, especially after flexural yielding.

The proposed analytical method will improve the understanding of effects of deterioration on structural members, and allow engineers to qualitatively assess load carrying capacity of deteriorated reinforced concrete bridge pier columns.
