关于内置十字型钢板补强圆形钢桥墩极限状态的研究

Research on Limiting State of Steel Pier Strengthened by Cross Steel Plate which Is Set up within It

论述的是利用非线性有限元分析内置十字型钢板补强圆形钢构件的极限状态。明确了轴压比参数和径厚比参数对内置十字型钢板补强圆形钢桥墩的极限承载力、极限应变的影响,取得了性能抗震设计安全评价公式,可为桥梁设计提供参考。

The paper discusses the limiting state to strengthen the round steel structure with cross steel plate set up within it,whicia is and radius thickness ratio analyzed by nonlinear finite element. It defines influence of axial pressure ratio parameter 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.
