[提要]  對所提出的一種新型預制四角錐輕型網(wǎng)架結構體系，從理論分析、足尺模型試驗及工程應用等方面進行了系統(tǒng)、詳細的分析研究。研究表明，該結構體系制作安裝方便，成本低，具有明顯的技術經(jīng)濟效果，為中小跨度的建筑提供了一種簡易可行的新型網(wǎng)架結構體系。
[關鍵詞]  預制四角錐  網(wǎng)架  結構體系

A new type of light-weight space truss consisting of prefabricated pyramidal units is presented. The new structural system is studied in detail through theoretical analysis,full-scale model test and engineering application. Research results show that, this system is easy to manufacture and erect,its cost is lower than ordinary space truss,it has obvious technical economic effect and provides a feasible space truss system to middle-span or small-span structure.
