A efficient 3D reinforced-concrete beam element based on the flexibility method and distributed nonlinearity theory is proposed, The sections of the beam element are divided into the plane isoparametric elements in this formulation, the section stiffness matrices are calculated through the integration of stress-strain relations of concrete including reinforcing steel effect in the section. The flexibility matrices of the sections are calculated by inverting the stiffness matrices, and the element flexibility matrix is formed through the force interpolation functions. The element stiffness matrix is evaluated through the element flexibility matrix. Finally, the buckling behaviors of a reinforced concrete beam under various eccentric loads are analyzed with the proposed formulation to illustrate its accuracy and computational efficiency.

Scrutiny of reinforced concrete beam by Ansys with non-identical collapsed mechanisms under assorted conditions. As per is code: IS: 456-2000. to evaluation for finite element examination a beam element various kinds of authors are done their research by using software’s like Ansys, abacus, civil FEM, mat-lab from this one they are studied based on various types of work flows regarding fracture proliferation patterns, in this journal i would like to do numerical examination by FEA software as well as experimental work repercussion analogy from data source. Potential of work is based on the design conditions of design of singly reinforced beam doubly reinforced concrete beam.

The response analysis of reinforced concrete (RC) structures subjected to strong earthquake motions require realistic conceptual models. The special models, such as Clough and Takeda, which describe the non-linear section characteristic of reinforced concrete beam and column. In the earthquake motions, the deforming is sensitive to the response of structures intensively. The traditional lumped plastic model inevitably induces inaccuracy. Hence, meshing the members or distributing stiffness along the whole member is employed to simulate the seismic response of the structures. In this paper, Takeda elastic-plastic beam element model has been developed, which is based on general FEM code ABAQUS in order to simulate the response of RC. The influence is discussed due to the different lengths of plastic zone and element sizes.

Based on the simulated results of joint of SRC beam and RC column (steel reinforced concrete beam and reinforced concrete column) with steel anchor, an analytical research on failure models and shear performance of three types of joints is conducted, which is composed of SRC beam and RC column, of SRC beam and column (steel reinforced concrete beam and column) and of SRC beam and ASC column (steel reinforced concrete beam and angle-steel concrete column). Then the parameters analysis for joint of SRC beam and ASC column is carried out, and the design formula of shear capacity for joint of SRC beam and ASC column is given on account of a great number of calculated and statistic results.

 A computational model of deformation of a flat-stressed reinforced-concrete composite element in the contact zone is proposed. Deformation equations takes the form of the relationships between the final increments  of stresses and deformations for a corrosion-damaged reinforced concrete element with intersecting cracks. Coefficients of flexibility matrix of the element are obtained. These coefficients take into account the long-term deformation,  corrosion damages and concentrated shear, when intersecting cracks appear in the contact zone of the composite element. The solution to reinforced-concrete beam of composite section is given. The computational results are compared with the experimental data for such structures.

This work examines the results on the Reinforced concrete beam element under different temperature scenario. The most contagious or maximum temperature distribution in the RC member will be presumed. In Reinforced concrete beam the flexural failure is vigorously reached by the temperature, and also steel reinforcement has experienced. The present work has studied the two-dimensional static analysis in the ABAQUS finite element software when the temperature remains in the steady-state condition during incremental loading applied in the member. The numerical results show that the temperature distribution in the beam element,load versus deflection curve ,ultimate load, Maximum principal stresses are done in the RC beam under different temperature. There fore the reinforced concrete 3D model is usefull in analytical tool for prediction of the behaviour of RC beam under temperature.

A efficient 3D beam element based on the distributed nonlinearity theory is proposed for nonlinear analysis of reinforcement concrete structures. The sections consist of reinforcing steel and concrete in this formulation and the section stiffness matrices are calculated through the integration of stress-strain relations of concrete and the accumulation of reinforcing steel effect. The force-based formulation is adopted in the evaluation of the element stiffness matrix and the element state determination. The improved Kent-Park model is adopt for the stress-strain relation of concrete, and uniaxial stress–strain relationships proposed by Mander is introduced for reinforcing steel. Finally, the ultimate load of a cantilever reinforced concrete beam subjected to a lateral load was analyzed with the proposed formulation to illustrate its accuracy and computational efficiency.
