【摘要】 通过静力抗弯刚度等效的原则,分别建立了波纹钢腹板箱梁与普通混凝土腹板箱梁的计算模型,对比分析了二者的动力特性。计算和分析结果表明,采用波纹钢腹板可以有效减小结构的自重,但其抗扭刚度相对较低,可以通过增加横隔板的方法增加其抗扭刚度。更多还原

【Abstract】 According to the static force flexural rigidity equivalence principal,concrete box-girder with corrugated steel webs is compared with normal concrete box girder to study their dynamic characteristics.The results of the research indicate that the weight of the girder could be reduced.But the torsional stiffness of concrete box-girder with corrugated steel webs is less comparatively.Setting transverse bulkheads can enhance the torsional stiffness.更多还原
