本文介绍丁部分预应力粱的一个简易设计方法,它可以快速解出T形梁,而其它形式的粱可通过忽略受拉翼缘而形成T形截面梁。使用荷载与极限荷载的要求应结合在一起考虑,以设计出最佳的钢筋面积。设计图和表列系数包括钢筋混凝土和全预应力混凝土之间的全部范围,也考虑了应力试算问题。
In this paper, we introduce a simple design method for prestressed beams of some parts, which can quickly solve T-beams, while other types of beams can form T-beams by neglecting the tension flanges. The requirements of load and ultimate load should be considered together to design the optimum rebar area. The design and tabular coefficients include the full range between reinforced concrete and fully prestressed concrete, as well as stress trial calculations.
