研究了ASTM A-36钢管梁柱的弹塑性性能。给出了钢管梁柱的三次试验结果。这些试验表明，管状截面明显强于类似的宽法兰截面。当梁柱承受相对较大的轴向载荷时，这一点尤为明显。本文还对梁柱的管状结构进行了理论研究。推导了无残余应力的管状截面弯矩-轴向载荷-曲率比的理论曲线。对曲率值进行数值积分，得到理论梁柱屈曲载荷。这些数据与目前梁柱的分析方程进行了比较。
The elastic and plastic behavior of ASTM A-36 tubular beam columns is studied. Experimental results for three tests of tubular beam columns are presented. These tests show that the tubular section is appreciably stronger than a similar wide flange section. This is especially apparent when the beam column is subjected to a relatively large axial load. A theoretical investigation of the tubular shape of a beam column is also conducted. Theoretical moment-axial load-curvature ratio curves are derived for the tubular section with no residual stresses. Values of curvature are numerically integrated to obtain the theoretical beam column buckling load. These data are compared to current analysis equations for beam columns.
