（哈爾濱工業(yè)大學建筑設(shè)計研究院，哈爾濱150090）[摘要] 對大跨度結(jié)構(gòu)上部高度空問的利用進行了初步探討。論述了材料承載力（強度力）性質(zhì)及與作用力的區(qū)別。由內(nèi)力分析結(jié)果，給出適用于預應(yīng)力復雜結(jié)構(gòu)體系中各構(gòu)件截面的計算公式。對兩類極限狀態(tài)計算公式給予了充分論證，也得出了給結(jié)構(gòu)體系施加預應(yīng)力，使其能夠承受更大荷載作用的根本原因。

In analysing result from the internal force ,giving a prestressing force out complicated structure system every member cross section calculation formula. Both limits state calculation formula were gave sufficient demonstration. After the system having explained structure exerts prestressing force, be able to bear bigger load effect cause.
Keywords: frame arch cable beam; action internal force; bear the force; strength force; molecular force.
