According to calculating conclusion, the beam without slab restricted on both sides isn′t common bending member,it is a tension and bending member existing torque,it should be reinforced according to calculating conclusion,and should meet with the detail of tension and bending member. Due to increasing calculating height of column beyond several floors, its longitudinal bar will be increased, especially on column beyond more floors.It gives design suggestion.Keywords:floor partial opening；beams without slab restricted on both sides；columns beyond several floors*西部災害與環(huán)境力學教育部重點實驗室（蘭州大學）2007年開放基金（編號2），甘肅省建設廳2007年度科技項目（編號：JK2007-4）。作者簡介：張敬書，副教授，一級注冊結(jié)構(gòu)工程師，Email：zjs66cn@yahoo.com.cn。參考文獻［1］陳岱林，李云貴，魏文郎.多層及高層結(jié)構(gòu)CAD軟件高級應用［M］.北京：中國建筑工業(yè)出版社，2004.［2］GB50003—2001砌體結(jié)構(gòu)設計規(guī)范［S］.
