摘要
该文重点讨论了预应力混凝土构件纵向受力性能的计算方法和计算过程,以及对新规范的一些理解,其中包括汽车冲击系数、上下缘正负温差、翼缘有效宽度、极限承载能力(塑性)和应力(弹性)计算等,同时也说明了一些构造方面的要求。
The article focus the discussion on the calculation method and the calculation process of longitudinal bearing performance of prestressed concrete component,and some understanding on the new standards,including the calculation of the automotive impact coefficient,positive and negative temperature differences of the upper and lower brims,efficient width of the wing brim,ultimate bearing capacity(plasticity)and stress(elasticity),at the same time,also explains some requirements of construction aspect.
