It shows that finite element analysis could replace experiments to study the crack width of reinforced concrete beams in a way. 说明有限元分析在某种程度上可以代替试验对钢筋混凝土梁裂缝宽度进行研究分析。
They would certainly be less pleasing to the eye and often more expensive than the prestressed concrete beam. 与预应力混凝土梁比较,它们自然更显得外貌粗拙,不甚美观,而且成本也往往更高一些。
