The difference of initial prestress and force in the members between experiment results and numerical results is small
2.
Dong shi - lin , yuan xing - fei . a quick calculation method for initial prestress distribution of geiger domes j . spatial structures , 2003 , 9 ( 2 ) : 38 , 19
3.
The dynamic properties of the tensegrity that is combined by some modes is investigated in the effect of initial prestress and external force , some results are got
4.
The model experiment shows that the construction techniques of moving outer diagonal cable are effective . the experiment model of sunflower - patterned cable dome is designed . the static behavior and initial prestress are measured
5.
By analyzing a monofilament cable , it is presented the conclusions that the influencing factors of the load - carrying properties of flexible supporting s stem include the initial prestress the diameter of tension rod or cable , the rise ratio and the height of the structure etc
6.
It shows that the method suggested in the paper is simple , applicable for engineering and has good precision . on the bases of the formulas deduced , and combining with relative test datas , it studies in the paper several factors influencing the bearing performance of the simple beams , such as shape of the external tendons , the equal moment segment length , span - to - depth ratio of the beam , valid initial prestress of the external tendons , area of the internal tension reinforcement , strength of the concrete , vertical distance between
7.
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
8.
The solution of initial prestress considering dead load is presented , which is more accurate . the calculation model of sunflower - patterned cable dome is built up . the static behavior of sunflower - patterned cable dome and sunflower - patterned cantilever roof is analyzed by ansys program and its results show that thesis two structures have good stiffness and load capability
