摘要
本文设计并完成了一榀10m跨索支承实腹式预应力钢拱模型试验.通过对不加预应力的普通拱以及两种不同索支承钢拱的静力试验,不仅验证了索支承钢拱结构在承载性能上的优越性,而且得到了在预应力施加过程中以及在荷载作用下索支承钢拱结构内力和变形的变化规律.试验还就索支承钢拱的节点构造形式进行了探讨.本文还采用混合有限元法分析试验模型,并与试验结果进行了对比分析.
A model test on a 10m span cable-strut arch frame was designed and carried out in this paper. Through static load tests on structures without prestress and structures with different supporting condition, not only the superiority of cable-strut arch frame over common arch frame was confirmed, but also some mechanical characteristics of cable-strut arch frame were found. During the experiment, the construction of joint detail was also studied. The model was analyzed by the mixed finite element method and comparison of the oretical and experimental results was also carried out.
