为研究均布荷载作用下剪切效应对简支加固梁弯曲性能的影响.文中基于材料力学和弹性力学理论,运用解析法得到了均布荷载作用下,简支加固梁弯曲应力方程和挠曲线表达式,并利用ANSYS数值模拟法进行比较验证,同时讨论了剪切效应对加固梁弯曲变形的影响.结果表明文中方法对计算简支加固梁弯曲问题,具有计算简便、精度高等优点,能满足一般工程设计要求.同时,剪切效应对简支加固梁的弯曲变形有着较大的影响,且随着跨高比的减小,影响作用逐渐增加.
STUDY ON THE BENDING PROPERTIES OF SIMPLY SUPPORTED REINFORCED BEAMS CONSIDERING WITH SHEAR EFFECT
This paper studies the shear effect of uniform load on bending properties of simple supported reinforced beams.Based on the theory of material mechanics and elastic mechanics,the bending stress equation and deflection curve expression of the simply supported reinforced beam under uniform load are derived,which is verified by the nu-merical simulation method of ANSYS.The results show that the proposed method has the advantages of simple calcu-lation and high precision in calculating the bending problem of simple supported reinforced beams,meeting the re-quirements of general engineering design.And the shear effect has a great influence on the bending deformation of the simple supported reinforced beam,and the influence gradually increases with the decrease of the span height ratio.
