环肋圆柱壳肋骨侧向稳定性加强措施研究
Study on the improvement measurements for frame tripping in the ring stiffened cylinders
【摘要】 根据肋骨侧向失稳的特点,通过对四种加强措施的分析比较,论证了加强形式对改善肋骨侧向稳定性的有效性,并用理论方法计算了有效约束在周向布置的数量,最后指出周向设置适当数量的整肋距肘板可有效改善肋骨的侧向稳定性.
【Abstract】 According to the characteristics of frame tripping, this paper discussed four improvement measurements to improve the frame tripping and predicted the proper number of side stiffener by the theoretic method. Finally it is pointed out that the sufficient brackets connected the adjacent frames are effective for improving the frame tripping.
