【摘要】 基于本试验和目前国内全部预应力混凝土叠合梁正常使用阶段试验结果 ,探讨了预应力混凝土叠合梁在正常使用阶段的受力特征 ,提出了可用于正常使用极限状态控制的计算公式 ,并与普通预应力混凝土梁的相应计算形成统一理论体系更多还原

【Abstract】 Based on the results from the authors’ test and the nation’s test on the prestressed reinforced concrete composite members under normal service conditions, the paper discusses the mechanical properties of the prestressed reinforced concrete composite members under normal service conditions, and suggests a method used for the control of ultimate state under normal service conditions. A unified theoretical system fits both the composite beams and ordinary beams.更多还原
