Based on this discussion, the dissertation attempts to establish a framework for translation from a sociosemiotic perspective, emphasizing that Peirce's triadic division of a sign can be used to explicate translation in a macro point of view and that Morris's famous three types of meaning can be applied to the actual translation practice. From this, it can be clearly shown that a sociosemiotic theory is a sound one in its application to translation.

The current research points out that for the CFCHS joints the linear extrapolation method can be used for chords,whereas the quadratic extrapolation method must be used for braces.The hot spot stress distributions on the CFCHS joints tend to be more uniform and their SCFs become smaller significantly,compared with the CHS joints.Axial tension on the brace puts the CFCHS joints at a disadvantage,which produces higher SCFs than axial compression.The effects of nondimensional geometric parameters β,τ and γ on SCFs of the chords of the CFCHS joints are basically the same as those of the CHS joints,but for the braces,there is a bit difference in the effects of parameters β,τ and γ between the two kinds of joints.Concrete has the function of improving the CFCHS joint rigidity and then decreasing SCFs which is expected to increase fatigue strength,but concrete strength grade does not exert significant influence on SCFs.

研究表明：CFCHS节点的热点应力，对主管可采用线性外推方法，对支管需采用二次外推方法；相比CHS节点，CFCHS节点的热点应力分布趋于均匀，SCF显著减小；CFCHS节点支管轴向受拉比受压不利，SCF增大；CFCHS节点几何参数β，τ，γ对主管SCF的影响效应与CHS节点基本一致，但是对支管SCF的影响效应与CHS节点有些差异；混凝土的作用主要是改善CFCHS节点刚度，从而降低SCF，并预期可提高疲劳强度，但混凝土自身强度等级的高低没有显著影响节点的SCF。
