[提要]  編制了鋼筋砼雙向拉彎構(gòu)件的正截面承載力計(jì)算的計(jì)算機(jī)程序，可用于各類(lèi)型截面的計(jì)算。并用此程序?qū)匦谓孛?、等肢L形截面、T形截面和十形截面在雙向拉彎作用下的N-M相關(guān)曲線、等軸力下的胍- My相關(guān)曲線進(jìn)行了分析研究。
[關(guān)鍵詞]  鋼筋砼 異形截面 雙向拉彎 正截面承載力 計(jì)算機(jī)程序

A theoretical analysis and research on the bearing capacity of reinforced concrete members under axial tension and biaxial bending are achieved. A computer program was compiled to study the interaction diagrams (N-M) and (Mx-My) with arbitrary shaped cross-section subjected to axial tension and biaxial bending.
Keywords: reinforced concrete; arbitrary shaped section; axial tension-biaxial bending;  bearing capacity
