| Abstract: | The paper discusses the limiting state to strengthen the round steel structure with cross steel plate set up within it,which is analyzed by nonlinear finite element.It defines influence of axial pressure ratio parameter and radius thickness ratio parameter on the limiting bearing capacity and limiting strain to strenghen the round steel pier with cross steel plate set up within it,having achieved the formula for safely estimating the aseismatic design of bridge,that might offer reference for aseismatic design of bridge another. |
