通过对15个型钢混凝土梁构件(只改变内置型钢上翼缘宽度)的梁中单调加载试验进行有限元模拟,从有限元的计算结果以及理论分析得出,型钢混凝土梁构件内置型钢的上翼缘的宽度与下翼缘之比为0.7~0.8时,对核心区混凝土有高效约束,同时核心区的混凝土对内置型钢翼缘有有效的支撑,并且内置型钢、钢筋和混凝土都能充分发挥其力学性能,即达到最佳经济模式。
通過對15箇型鋼混凝土樑構件(隻改變內置型鋼上翼緣寬度)的樑中單調加載試驗進行有限元模擬,從有限元的計算結果以及理論分析得齣,型鋼混凝土樑構件內置型鋼的上翼緣的寬度與下翼緣之比為0.7~0.8時,對覈心區混凝土有高效約束,同時覈心區的混凝土對內置型鋼翼緣有有效的支撐,併且內置型鋼、鋼觔和混凝土都能充分髮揮其力學性能,即達到最佳經濟模式。

Through the finite element simulation on beam monotonic loading test of 15 steel reinforced concrete beams(only changed the built-in steel flange width),from the finite element computed results and theoretical analysis,gained the top flange width and the bottom flange width ratio of 0.7~0.8 of steel reinforced concrete beam structure built-in steel,to core concrete had an efficient constraint,while the core area concrete to built-in steel flange had effective support,and the built-in steel,reinforcing steel and concrete could all give full play to their mechanical properties,namely to achieve the best economic mode.
