(乙)底板检算底板与腹板连接处(截面a-a)以及斜梗肋起点处(截面 b—b)的钢筋应力与腹板钢筋的应力检算相同,底板的钢筋应力亦按主梁轴向的弯曲剪力,和由于箱形截面的刚架作用产生的弯矩,以及由于荷载的偏心产生的扭矩进行计算。(I)作为腹筋由于弯曲剪力产生的应力(σsb)各截面的应力σsb 为: (B) The soleplate is checked that the stress at the connection between the bottom plate and the web (section aa) and the start point of the inclined stem (section b-b) is the same as the stress calculation of the web reinforcement. Bending shear forces, bending moments due to the rigid frame action of the box section, and torque due to eccentricity of the load are calculated. (I) Stress (σsb) due to Bending Shear as Abdominal Force The stress σsb of each cross-section is:
