关于混凝土开裂对柔性桥墩内力影响的研究

A Study of the Influence of Concrete Cracking on the Internal Force of Flexible Piers

提出了混凝土开裂影响的柔性桥墩内力的实用计算方法，并编制了程序。该方法纠正了以往墩内受力较大的假象（尤其对于较矮柔性墩），充分挖掘了柔性墩设计中的潜力，用钢量也明显减少，具有较大的经济效益。

A practical calculating process of the internal force of flexible piers is put forward, taking into account the influence of concrete cracking. This process rectifies the existingfalse phenomenon that the internal forces are considerably large(especially in low flexible piers).As a result,the potentialities in flexible pier design can be fully exploited,and the amount of steelconsume remarkably reduced.
