摘要
对平板网架与曲面网壳结构施加异钢种预应力，可使网格结构刚度更好，经济技术指标非常优良。本文通过国内外尚无先例的几个预应力网格结构工程实践和组合式预应力双曲扭网壳１／１０缩尺模型试验分析与对比，证明预应力网格结构在２１世纪空间结构领域内，将有十分美好的前景。
Abstract To apply pastiress on different steels in double-layer grid structures and reticulated shellstructures can improve the rigid of the structures and achieve remarkable economical-technical resultsIn this paper, based on analyzing some engineering examples which are unprecedented at home andabroad and testing the 1/10 scaled model of composite hyperbolic prestressed twisted reticulated shellstructures, it is ptoved that there wili be a vast good application prospect of prestressed reticulatedstructure system in the space structure field in 21st century.
