  1. The cable - strut tensile structures are the self - stress equilibrium systems composed by tensional cables and struts. in this paper, the basic concept of the structures was described. the analysis methods of the structural characteristics ( statically and kinematically determinate or indeterminate ) and the geometrical stability were presented. it is indicated that the cable - strut tensile structures are in stable equilibrium with first - order infinitesimal mechanisms. the ranks of equilibrium matrix were calculated by employing the singular value decomposition, and the independent modes of inextensional mechanisms and the states of self - stress were also obtained in the same way. this paper contains some typical examples which illustrate all of the main points of the work

    索桿張力結構是指由張力索和壓桿組成的、具有預應力自平衡的新穎結構體系.本文詳細闡述這種結構的基本概念和結構特徵，討論結構靜動定體系特性和幾何穩定性判定分析方法，指出索桿張力結構應具有一階無窮小機構的幾何穩定體系.文中採用奇異值分解方法計算結構平衡矩陣的秩，並計算獨立機構位移模態和自應力模態.最後，對幾種典型的索桿張力結構進行了算例分析
  2. And the procedure of solving initial prestress by equilibrium matrix theory and simplified method are elucidated. the self - stress mode of sunflower - patterned cable dome must be positive, and the mechanisms mode equals to zero. it seems like statically indeterminate structures and is geometrical stable structure

    明確了葵花型索穹頂結構形態分析的具體內容；闡述了用平衡矩陣理論和簡化演算法求解索穹頂結構初始預應力的過程，指出葵花型索穹頂結構的自應力模態s 0且機構位移模態m = 0 ，相當于結構力學中的超靜定結構，同時它也是幾何穩定的結構；提出了考慮結構自重時葵花型索穹頂結構初始預應力的求解方法，這種方法求得的初始預應力更加準確。
  3. Rigid - framed arch bridge is a statically indeterminate structure with thrusting force and over the cross section of the bridge structure induce obvious stresses resulted from temperature variations. however, because of the complexity of this bridge structures, it is so difficult to calculate temperature stress, and that researchers and designers have to simplify the calculating methods, and get inaccurate conclusions

    剛架拱橋是一種有推力的高次超靜定結構，溫度效應對其的影響相當明顯；但由於其構造復雜，計算結構的溫度應力存在著很大的困難，這就使得研究和設計人員採取簡化的計算方法，但得出的結論粗糙。
