单排桩柱墩压杆的计算长度

Calculated length of compression bar in pile bent column pier

基于小挠度理论推导了等截面直压杆和变截面直压杆的通用稳定特征方程,通过对稳定特征方程进行试算可得出压杆的计算长度;此外,还探讨了单排桩柱墩杆端水平和转动方向弹性约束刚度的确定方法.

Based on little deformation theory, the general stability characteristic equations for the straight compression bars with both constant and variable cross - sections are derived so as to find the calculated length of compression bar by trial method. The calculation of the rigidity of elastic restraint at the end of pile bent column pier is also discussed here.
