【摘要】：以佛山世紀(jì)蓮體育中心為工程背景,通過定性模型試驗(yàn)測試及原型結(jié)構(gòu)有限元分析,系統(tǒng)研究不同構(gòu)件斷裂情況下輪輻式索膜結(jié)構(gòu)動力響應(yīng)及連續(xù)倒塌性能。結(jié)果表明,該輪輻式索膜結(jié)構(gòu)主要構(gòu)件重要性由小到大依次為懸掛索、腹桿、下壓環(huán)、上壓環(huán)、墩柱、分叉索、脊索、谷索、內(nèi)環(huán)索;重要構(gòu)件斷裂造成的破壞程度由輕到重依次為一根谷索斷裂、一根脊索斷裂、兩根相鄰谷索斷裂、兩根相鄰脊索斷裂、墩柱斷裂、兩根相鄰索斷裂、三根相鄰索斷裂、內(nèi)環(huán)索斷裂;該結(jié)構(gòu)具有較好的抗連續(xù)倒塌能力,重要桿件裂后,能將其承擔(dān)的荷載迅速傳遞給相鄰構(gòu)件,較好地將坍塌部分限制在有限區(qū)域內(nèi);通過采用雙索體系、分區(qū)域設(shè)計(jì)及多柱式墩可提高結(jié)構(gòu)抗倒塌能力。
[Abstract]:Based on the engineering background of Shilian Sports Center in Foshan City, the dynamic response and continuous collapse performance of spoke cable-membrane structures under different fracture conditions were systematically studied by qualitative model test and finite element analysis of prototype structures. The results show that the importance of the main components of the spoke cable-membrane structure is the suspension cable, the web bar, the lower pressure ring, the upper pressure ring, the pier column, the bifurcation cable, the notochord, the valley cable and the inner ring cable. The degree of failure caused by the breakage of important components from light to heavy is in the order of one cereal cord, one chord, two adjacent valley cables, two adjacent chordes, pier column, two adjacent cables, three adjacent cables, two adjacent cables, three adjacent cables, two adjacent cables and three adjacent cables. The inner ring cable fracture, the structure has better ability to resist the continuous collapse, after the important members crack, it can quickly transfer the load it bears to the adjacent members, and better limit the collapse part in the limited area; by adopting the double cable system, Regional design and multi-column pier can improve the collapse resistance of the structure.
