摘要
针对正常使用荷载下允许出现裂缝的预应力型钢混凝土梁,推导了开裂截面的中和轴高度方程,并给出了该三次方程的近似解和解析解,为进一步深入理解其正常使用性能打下了基础。
In this paper,the equation of neutral axis at the crack section of prestressed steel reinforced concrete(PSRC) beam was deduced,which allowed a limited width of cracks under service loads.Different solutions to the equation were given so that the distribution of stresses at the crack section could be acquired.All that laid a foundation for further studies on the properties of PSRC beams under service loads,such as the width of cracks,deflection, fatigue,etc.
