【摘要】 假定周围介质的约束反力与型钢的位移成正比,通过理论分析推导了约束整体稳定计算式.结果表明,周围介质的侧向约束作用显著提高了钢梁的整体稳定承载力,计算长度超过某一界限长度后其临界弯矩不再降低.更多还原

【Abstract】 In this paper,it is assumed that the restriction of medium around the steel beam is in direct proportion to the lateral movement of the steel beam.The formula for integer stability calculation of reinforced soil-cement mixing wall has been deducted by theoretical analysis.It proves that the lateral restriction of medium has enhanced the integer stability of steel beam,and the critical bending moment would not decrease when the length exceedes a certain point.更多还原
