Abstract:
The finite element analysis method of seismic performance of four-element variable cross-sectional concrete-filled steel tubular(CFST)laced column was put forward. The specimens were modeled and analyzed by the OpenSEES general program, and the load-displacement hysteretic curves and horizontal peak loads of laced columns were computed. The influence rules of longitudinal slope, axial compression ratio, slenderness ratio, area ratio of lacing tubes to longitudinal tubes, yield strength of steel, concrete strength, arrangement type of lacing tubes, and other extension parameters on the skeleton curves of variable cross-sectional CFST laced columns with flat or inclined tubes were investigated. According to the calculation frame of skeleton curves of equal sectional CFST laced columns, the calculation formulas of skeleton curves characteristic values(including the elastic stiffness, horizontal peak load and its displacement, and fall-period stiffness)of four-element variable cross-sectional CFST laced columns were obtained by the equivalent length method. The calculation formula of restoring force model was deduced resorting to the calculation model of skeleton curve and verified by the engineering example. Research result indicates that the axial compression ratio, slenderness ratio, longitudinal slope, area ratio of lacing tube to longitudinal tube, and material parameters are the main influence parameters on the seismic performance of variable cross-sectional CFST laced columns, the common influence rules are the same as the rules on the equal section laced column, and the numerical difference is within 20%. The calculated results of characteristic values of each specimen are in good agreement with the finite element analysis results, and their ratios are 0.990-1.029, the mean square errors are 0.105-0.153, and the errors are basically controlled within 15%. The errors to calculate the restoring force model of four-element variable cross-sectional CFST laced columns are within 12%, so the computation result is reliable. 2 tabs, 21 figs, 32 refs.
