第二十三讲介绍了中心受拉构件的计算,本讲介绍偏心受拉构件的计算。偏心受拉构件与中心受拉构件不同之处在于:前者受到的纵向拉力的作用点偏离了构件截面的形心,因此偏心受拉构件除了受到纵向拉力N外,还受到一个弯矩M的作用。而M=Ne_0,式中e_o为纵向拉力作用点与截面形心的 The twenty-third lecture introduced the calculation of the center tension member. This lecture introduced the calculation of the eccentric tension member. The difference between the eccentric tension member and the central tension member is that the point of application of the longitudinal tensile force of the former deviates from the centroid of the cross section of the member. Therefore, the eccentric tension member is subjected to a bending moment M in addition to the longitudinal tension N. . And M=Ne_0, where e_o is the longitudinal tensile force point and cross-sectional centroid
