Finite Element Analysis (FEA) for the Beam-Column Joint Subjected to Cyclic Loading Was Performed Using ANSYS

PurposeSteel fibers reinforced concrete (SFRC) is now widely accepted as a construction material for its added benefits. The proven increases in high shear capacity, toughness, bridging action of fibers and bond improvement from addition of steel fibers into mix design is a field yet to be explored, Therefore, Reinforced Cement Concrete (RCC) beam-column joint with steel fibers was modeled and analyzed for cyclic loading.Design/methodology/approachBeam-column joint is the most critical section of a structure under mixed loading such as that during a seismic episode. Therefore, in this research a reinforced SFRC beam column joint is modeled and analyzed for cyclic earthquake loading with the help of finite element analysis (FEA) software ABAQUS to compare the results with the experimental study.FindingsNonlinear static and nonlinear dynamic analysis are carried out on the SFRC joint for the comparison of simulated results with the experimental analysis.Originality/valueIn this paper, Initially, modeling of SFRC joint was done. Then, the finite element analysis of beam-column joint with steel fibers was carried out. After number of simulations, obtained FEA results were compared with the experimental work on the based on the load vs deflection curve, shear stresses, plastic strain region and plastic strain pattern. After the comparison, it was found that the performance of the numeric model for cyclic loading verified the experimental study, and the results obtained were quite promising.

Parametric Studies

In this study, detailed finite element analysis was conducted to examine the seismic performance of square and circular hollow steel braces under axial cyclic loading. Finite element models of braces were constructed using ABAQUS finite element analysis (FEA) software and validated with experimental results from previous papers to expand the specimen’s matrix. The influences of cross-section shape, slenderness ratio, and width/diameter-to-thickness ratio on hysteretic behavior and compressive-tensile strength degradation were studied. Simulation results of parametric studies show that both square and circular hollow braces have a better cyclic performance with smaller slenderness and width/diameter-to-thickness ratios, and their compressive-tensile resistances ratio significantly decreases from cycle to cycle after the occurrence of the global buckling of braces.

Dowel Bar

Small concrete cover to dowel’s diameter reduces the cyclic performance of precast concrete frame with pinned dowel beam-column connection due to brittle concrete splitting failure around the dowel joint. Besides, utilisation of bearing pad thicker than half of dowel’s diameter causes the dowel bar to sustain greater tensile stress and plastic elongation up to their breaking point due to larger inclination of the dowel bar, particularly under the action of cyclic loading. Hence, a new precast beam-column joint with hook-end configuration and utilizing the advantage of high damping rubber (HDR), was proposed as the alternative for precast structures. Therefore, this study presented the horizontal and vertical cyclic performances of the precast frames with the proposed joint, through numerical analysis using finite element software. The numerical results were compared with a numerical modelled single pinned dowel connected precast frame, which was verified with the experimental results under horizontal cyclic loading. In terms of accumulative energy dissipation capacity, the numerical results showed that precast frames with the proposed joint demonstrated approximately 230% and 120% of improvement at 40 mm of horizontal cyclic level and 7 mm of vertical cyclic level, respectively, than the precast frame with single pinned dowel connection. It indicates that the viscoelastic behavior of HDR has contributed the benefit in this improvement.
