The analysis result on prestressed concrete slab - column structure in regular column layout is closed to that of actual situation . for slab - column structure of variable slab width , approximation is needed or is replaced by fem 等代框架法對規(guī)則板柱結(jié)構(gòu)的分析比較接近真實(shí)情況,對板帶寬度變化的板柱結(jié)構(gòu)則需作近似或改用有限元法來計算。
Prestressed concrete slab - column structure has been widely used in long - span and multistory building . there are four commonly used analysis methods for slab - column structure , which are direct design method , equivalent frame method , plasticity method and finite element method 預(yù)應(yīng)力混凝土板柱結(jié)構(gòu)在大開間的多層及高層建筑中得到了廣泛的應(yīng)用,其設(shè)計方法有直接設(shè)計法、等代框架法、塑性分析法和有限元法等多種方法。
