［摘要］將傳統(tǒng)三心圓柱面網(wǎng)殼與聯(lián)方型巨型網(wǎng)格結(jié)構(gòu)結(jié)合，提出一種三心圓柱面巨型網(wǎng)格結(jié)構(gòu)，對(duì)其體型參數(shù)進(jìn)行分析，給出了結(jié)構(gòu)各參數(shù)計(jì)算公式。根據(jù)所得公式計(jì)算三心圓柱面巨型網(wǎng)格結(jié)構(gòu)各體型參數(shù)，針對(duì)結(jié)構(gòu)體型特點(diǎn)，改變參數(shù)（落地傾角、結(jié)構(gòu)矢跨比、弦段比例以及支承形式）建立不同模型，并研究結(jié)構(gòu)在靜力荷載作用下，內(nèi)力分布隨參數(shù)的變化情況，得出了較為經(jīng)濟(jì)合理的結(jié)構(gòu)體型，為之后的結(jié)構(gòu)設(shè)計(jì)提供參考。

Abstract: Combines the traditional three-centered cylindrical shell with the joint square type giant grid structure, a kind of three-centered cylindrical giant grid structure was proposed, its body parameters was analyzed, and the calculation formula of each parameter of the structure was gave. According to the formula, three-centered cylindrical giant grid structure size parameters were calculated. Based on the characteristics of structure size,  parameters (landing angle,  rise-span ratio of structure, string section proportion and supporting form) were changed to establish different models, and the internal force distribution of the structure under the action of static load changes with the parameters was researched, and a more economical and reasonable structure shape was obtained, which provides a reference for the subsequent structural design. 

Keywords:giant grid structure； steel structure； three-centered cylinder； shape parameter analysis; internal force distribution
