［摘要］單層折面網(wǎng)殼是近年來新興起的一種由三角形折面網(wǎng)格組成、外形如寶石群或?qū)毷w的單層網(wǎng)殼結(jié)構(gòu)。為改善單層折面網(wǎng)殼的受力性能、提高結(jié)構(gòu)剛度、優(yōu)化結(jié)構(gòu)設(shè)計(jì)，可在其基本結(jié)構(gòu)體系的基礎(chǔ)上增設(shè)若干道預(yù)應(yīng)力環(huán)索。以鉸接B6,8型單層折面網(wǎng)殼為例，通過模型靜載試驗(yàn)驗(yàn)證了理論分析的可靠性，對比分析了結(jié)構(gòu)施加預(yù)應(yīng)力前后的受力性能，并在施工張拉模擬試驗(yàn)的基礎(chǔ)上給出了合理可行的張拉施工方法。［關(guān)鍵詞］預(yù)應(yīng)力單層折面網(wǎng)殼; 試驗(yàn)研究; 模型設(shè)計(jì); 靜力加載; 施工張拉中圖分類號：TU394 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2016)04-0015-07
Experimental study on prestressed single-layer folded-plane reticulated shell structureXing Dong1,2, Dong Shilin2, Liu Changjiang1, Zhu Mingliang3（1 Institute of Civil Engineering and Architecture, Weifang College, Weifang 261061, China; 2 Space Structures Research Center, Zhejiang University, Hangzhou 310027, China; 3 College of Civil Engineering, Southeast University, Nanjing 210096, China）Abstract:The single-layer folded-plane reticulated shell which is proposed recently is a kind of single-layer reticulated structure composed of triangular lattices, just like an assemblage of diamonds. In order to optimize behavior characteristic, structural stiffness and structure design of the single-layer folded-plane reticulated shell, several ring cables could be add up to the basic structure system. For further study, static loading experiment on B6,8 single-layer folded-plane reticulated shell was carry out. The theoretical solution result is in a good agreement with experiment result, a contrastive analysis about structural behavior before and after prestressed was made, and a reasonable prestressed construction method is suggested.Keywords:prestressed single-layer folded-plane reticulated shell; experimental study; model design; static loading; prestressed construction
