摘要
运用反设计方法,讨论了混凝土梁同时满足承载力和挠度、裂缝限值的最经济跨高比,分析了混凝土梁经济跨高比的设计思路,并证明了按此方法设计的混凝土梁是最经济的,给出了一个6 m跨简支混凝土梁的设计实例,以便展示此设计方法的具体应用。
Based on the inverse design, the author discusses that the most economical span-depth ratio of concrete beam which can satisfy the loading capacity, deflection and crack limit at the .same time, analyzes the design thought of concrete beam economical span-depth ratio, and proves that the concrete beam designed according to this method is the most economical, provides design example of a concrete beam with 6 m span simple supporting, so as to show the particular application of the design method.
