Nonlinear numerical analyses for the stress performance of SRC frame intermediate joints, side Joints and end joints are processed in this paper with the finite element software of ABAQUS. Compared with experimental results under static loading, numerical analysis results are found to be reasonable. Then the influence of factors such as shaped steel ratio and axial-load ratio are contrastively analyzed under cyclic loading. The results show that shaped steel ratio has a greater influence on the bearing capacity and hysteretic performance of the structure and with the steel ratio increases, the hysteretic performance is better. But the axial-load ratio has less influence.

Characteristic Value

Base on the experiment results of steel high performance reinforced concrete (SHPRC) structural walls, nonlinear finite element(FE) analysis is performed to simulate the complete process of the loading and concrete crack of SHPRC structural walls in the platform of ABAQUS. The nonlinear of material is taken into account in the models. The reliability of the finite element model is verified through the comparison of the analysis results and the experimental results. Based on the proposed model, the parametric analysis is carried out to study the effect of axial load ratio, aspect ratio, stirrup characteristic value, and steel ratio on the seismic behavior of SHPRC structural walls. It is concluded that the bearing capacity of SHPRC structural walls increase with the increase of the axial load ratio, but the deformation decreases obviously. The deformation and bearing capacity of the structural walls are improved by increasing the steel ratio. With increasing the stirrup characteristic value, the deformation of the structural walls improves significantly. The stirrup characteristic values are proposed to ensure the SHPRC structural walls for different axial load ratios meet the deformation capacity of drift ratio of 1/120,1/100 and 1/80, respectively.

Parametric Studies

Three full-scale exterior beam–column joints with anti-seismic steel reinforcement were tested under quasi-static cyclic loading and column axial compressive loading. The test variables were column axial load ratio and joint core hoop reinforcement ratio. Experimental results, including failure mode, hysteretic curve, ductility, energy dissipation, stiffness degradation, and decoupling of deformations, were presented and analyzed. The tests revealed that the anti-seismic rebar resulted in good joint seismic performance and that column axial load ratio and joint core hoop reinforcement ratio impose limited influence of joint performance when the joint failed in beam flexural failure. The calibrated finite element models developed based on OpenSees were then used to simulate the behavior of joint specimens. Parametric studies via finite element modeling were performed to study the influence of various parameters on the performance of beam–column joints.

This study was organized to derive simplified expressions to estimate the effective flange width for T-shaped shear walls at different loading stages. For that purpose, the variation in the effective flange width was explored by introducing dimensionless effective flange width coefficient. According to the principle of minimum potential energy, the theoretical expression of the effective flange width coefficient in the elastic stage was obtained. Furthermore, a parametric study considering the axial load ratio, height-width ratio of flange and width-thickness ratio of the flange, as well as the section aspect ratio was conducted to determine the effective flange width using verified nonlinear finite-element models. In light of the parametric analysis results, a formula model was proposed depending on the axial load ratio and height-width ratio of flange. Finally, the predictions of the proposed simplified formulas were verified with the theoretical solutions or finite element (FE) results, which indicated that the proposed formulas can accurately capture the effective flange width at the elastic, yield and limit state.

Nonlinear numerical analysis for the stress performance of RC beam - SRC column and SRC beam - SRC column frame end joints are processed in this paper with the finite element software of ABAQUS. Compared with experimental results, simulation results are found to be reasonable. In order to study the influence of steel bone content on the frame node, two kinds of frame joints are contrastively analyzed under monotonic loading and cyclic loading. The load-displacement curves and hysteretic curves show that with the steel ratio increases, the ultimate bearing capacity improves and the seismic performance becomes better.

SRC-RC transfer columns are commonly designed as a transition floor for high-rising buildings to transfer from lower SRC columns to upper RC columns. The mechanical performances are studied in the paper using the finite element software of ABAQUS. Nonlinear numerical analyses are made for SRC-RC transfer columns firstly to obtain the relationship between force and displacement at top of the columns. By comparing the analytical results with experimental ones, it is found that the results from finite element analysis coincide well with experimental ones. So ABAQUS software could be used as a supplementary means to simulate SRC-RC transfer columns mechanical behavior. Then the factors such as steel ratio and axial compression ratio are contrastively analyzed. The results show that axial compression ratio has a greater influence on the bearing capacity and hysteretic performance of the structure, but the steel ratio has less influence. Finally, comparisons between SRC-RC and RC columns are also made to demonstrate the mechanical performance of SRC-RC columns further. Conclusions drawn in the study might be useful in practical engineering design.
