The paper studied tests on three epiboly profiled bar concrete beams , bearing capacity of normal section , stiffness and behavior of cracks , and put forward formulas as advise . based on extant nonlinear concrete theory , a fem model was built by ansys program . the results of fem analysis was verified by tests data . some parameters in fem model were changed to build different models and the analysis results were compared with the advised formulas 本文通过三根外包型钢混凝土梁试验，研究了其正截面承载能力、刚度以及裂缝方面的性质，并提出了一些相关建议公式。同时在现有混凝土非线性分析理论的基础上，采用ansys有限元分析程序建立了外包型钢混凝土梁的有限元模型，结合试验数据对模型进行了验证，另外还改变了一些参数建立了有限元模型，并和建议公式的结果进行了对比。
