加腋预应力钢筋砼框架梁的设计
Design of Prestressed R. C. Frame Beam with Haunches
【摘要】 结合工程实例介绍了加腋预应力钢筋砼框架梁的设计方法,即通过加高支应处截面来增加其抗弯和抗裂能力.同时分析了加腋预应力梁的受力特点,给出了梁截面抗弯刚度为变数,形心线为非直线的计算处理方法.
【Abstract】 On basis of an engineering project,prestressed R. C. frame beam with haunches is introduced which can improve the flexural capacity and crack resistance by increasing the height of support section, this kind of beam’s feature is analysed and the calculation method is given to treat the condition in which the bending regidity is variable and the section centroid is not in one line.
