摘要
港口机械结构中的箱梁在承受压力作用时腹板容易失稳,需要在腹板上焊接加强筋来提高其稳定性。本文研究了腹板的失稳形式,同时对加强筋的强弱及连接方式对腹板屈曲的影响进行了计算比较。
Box girders on hoisting machinery's structural are prone to instable under the pressure,so it's necessary to enhance stability by welding stiffener on webs. This paper researchses the instable types of webs and compares the influence of the strength of stiffeners and the attended mode to the bucking of webs.
