摘要
以预应力木梁挠度等于零及预应力筋和木梁的应变协调一致为准则 ,分析和推导了预应力筋及其对预应力木梁承载能力的计算表达式 。
Taking deflection to be a zero and assuming that the strain for the timber beam and the prestressed bar should be compatible as requirements, the authors analyzed and derived the calculated equations of bearing capacity of the prestressed bar which is related to the timber beam. A theoretical principle has been offered in order to design a prestressed timber beam.
