Abstra ct: To further study of the mechanical properties of the new member and expand the
scope of application of special2shaped columns, based on the numerica l simulation method
and the finite e lement software ANSYS, the finite e lement analysismode l for spec ial2shaped
columns of yield2line stee l reinforced concret is set up. W ith the results from pres2
sion and eccentric load on yield2line SRC special2shaped columns, the force2d isp lacement
curve is determined. Comparing simulation results with experimental results, the both coin2
cide Its' re liable to use fin ite e lementmethod to analyze pression and b ias
capacity of stee l encased concret short columns with cross section. T
