The local strength of mooring system structure of FPSO is studied in this paper.
采用有限元分析方法，对多点系泊FPSO系泊结构的局部强度进行了研究。
The test for local strength of welded joints is necessary for strength design and load capacity estimation of the welded joints.
工程上进行焊接接头强度设计或承载能力评定时，需要测定焊接接头各区域的局部强度。
So it is hard to accurately calculate, and the design only works by experience, which will result in the lack of local strength or excessive safety margin and so on.
对于实际结构，由公式计算的结果往往误差较大，特别是高应力区域，难以精确计算，工程上只能采用经验设计，这样会导致结构的局部强度不足或整体安全裕度过高等不合理现象。
The DESIGN REGULATIONS of MIX RATIO of ORDINARY concrete (JGJ55-2000) definitely point out that the con ditioned areas should study and establish the local strength formula of concrete.
《普通混凝土配合比设计规程》JGJ55—2000中明确指出有条件的地区应研究建立当地的混凝土强度关系式。
It is advised that the global strength method should be better than the local strength method when the inhomogeneous slope is analyzed.
因此，采用强度折减法对非均质边坡进行稳定性分析时，建议对整个模型都进行折减。
