Local flexibility of tabular joints has large effects on the behavior of offshore platform struetures, such as nominal stresses, deflections, buckling lond, natural frequencies and mode shapes. Research tn the elffects of the cal joint flexikility has drawn attention in recent years, especially in design and investigation of deep water platforms In this paper, semi—analytical method is employed to calculate the local joint flexibility of tubular T. Y joints under loading conditions of axial forces and in-plane bending moments. The rosults show good agreement witk those calculated from empirical equations and the experimental data new available, Therefore, the semianalytical method turned oat effective in determining the local flexibility of tubular joints A simple frame structure is calculated in the paper. The effedcts of the local joint flexibility can be observed by conparison of the rumorical results from the conventional method and these from the method in which the local joint fleibility is taken into account.

海洋平台管节点局部柔度对平台结构的名义应力、变形、构件的稳定性及振动周期、模态等均有不可忽视的影响,这一现象对深水平台尤为重要。对管节点局部柔度的研究,近年来已逐渐引起了注意。本文用半解析法对T、Y型管节点在轴力与面内弯矩作用下的局部柔度进行了计算,所得的结果与国外已有的经验公式与试验结果比较,证明是足够精确的,从而证明了本文的方法可准确有效地用以确定管节点的局部柔度。为了说明管节点局部柔度对平台结构的影响,文中给出了对一简单结构分别用传统方法和计及节点局部柔度的方法计算的结果及比较。

TLP is the main platform in deep sea for its partly compliant and partly rigid feature. The interaction between wave and TLP includes two parts: one is wave diffraction, the other is wave radiation. Wave radiation is studied in this paper. In calculating the hydrodynamic parameters of TLP, TLP can be idealized into an array of stationary, truncated circular cylinders. An approximate method of equivalent plane waves is utilized to investigate the hydrodynamic interactions between the members of TLP's truncated...

Wave radiation is studied in this paper. In calculating the hydrodynamic parameters of TLP, TLP can be idealized into an array of stationary, truncated circular cylinders. An approximate method of equivalent plane waves is utilized to investigate the hydrodynamic interactions between the members of TLP's truncated vertical cylinder array which occur when one member undergoes prescribed forced oscillations.

张力腿平台作为一种深水平台 ,其半顺应半固定的运动特征 ,成为在复杂的深海海洋环境中进行海洋石油勘探、开采一种重要结构型式。在张力腿平台波浪载荷的计算中根据产生波动流场的因素不同将波浪载荷分为绕射效应和辐射效应。本文对辐射效应深入研究并以附加质量、附加阻尼等水动力参数的形式计算了辐射效应对张力腿平台的载荷影响。在计算水动力参数时将平台简化为浮式直立柱群 ,采用势流理论 ,引进改进平面波法计入柱体间水动力相互作用得到辐射波速度势的半解析解 ,引入大间距假设、通过非平面波修正 ,精确地求解了柱群的辐射波的载荷作用
