The span of the steel truss is 31m. Incorporating the results of computational analysis, several schemes of steel truss were compared. Finally, M shape web members and steel reinforced concrete at the lower chord bearing were adopted in the structural arrangement. The advantages and disadvantages of the truss were analyzed specifically.Keywords: North Guiyang Railway Station; steel truss; steel reinforced concrete; web member arrangement; closed profiled slab作者簡介：劉昶，工程師，Email：4755943@qq.com。參考文獻［1］邱劍，溫四清，熊巍，等.貴陽北站站房結(jié)構(gòu)設(shè)計［J］.建筑結(jié)構(gòu)，2012，42（9）：1-5.［2］劉勁松，裘濤，王翠坤，等.帶高位大跨鋼桁架轉(zhuǎn)換層建筑結(jié)構(gòu)動力分析［J］.建筑結(jié)構(gòu),2008，38(3):61-64.［3］溫四清，吳軍，邱劍，等.湖北省圖書館新館40m跨高位轉(zhuǎn)換桁架結(jié)構(gòu)設(shè)計［J］.建筑結(jié)構(gòu)，2012,42（7）：1-4.［4］GB 50017—2003鋼結(jié)構(gòu)設(shè)計規(guī)范［S］.北京：中國計劃出版社，2003.［5］譚燕，謝偉平. 閉口型壓型鋼板混凝土組合板發(fā)展綜述［J］.山西建筑，2007，33(6)：154-155.
