[提要]  從正截面承載力理論計(jì)算方法出發(fā)，介紹了《鋼骨混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)程》中簡(jiǎn)單疊加方法和改進(jìn)簡(jiǎn)單疊加方法，對(duì)幾種方法進(jìn)行了對(duì)比，并通過例題說明了有關(guān)計(jì)算方法的應(yīng)用。文中還介紹了鋼骨混凝土柱偏心距增大系數(shù)和軸壓力限值的計(jì)算。
[關(guān)鍵詞]  鋼骨混凝土 正截面 偏心距增大系數(shù) 軸壓力限值

Based on the theoretical method of normal section strength under flexure and axial force for steel rein-forced concrete members, the simple superposition method and the modified method adopted in the Specification for Design of Steel Reinforced Concrete Structure were introduced. Comparison was made for these methods. Some examples were given to show the usage of the methods. Besides, the eccentricity magnifying coefficient and the axial load linut for steel reinforced concrete column were also introduced.
Keywords:steel  reinforced concrete; normal section; eccentricity magnifying coefficient; axial  load limit
