利用 mathcad 及力法原理计算多跨连续梁的内力

摘要

应用力法原理对水工结构中的多跨连续梁进行内力计算，阐述如何利用mathcad软件程序使计算实现的过程，分析连续梁在均布荷载作用下的内力分布规律，与计算不等跨连续梁内力的传统方法进行比较，比较两种方法计算不等跨连续梁的内力可以看出利用mathcad计算显著提高计算精度，给其它结构工程中的连续梁内力计算提供参考，证明了mathcad软件在工程设计计算中的准确、有效、快捷。%Principle of the Force Method of Structural Mechanics is applied to Calculation of Internal Forces of Multi -span Continuous Beam in hydraulic structure , and the processes of calculation by means of Mathcad software are expounded , the distribution rule of internal force in uniform load condition is analyzed , the accuracy of calculation by Mathcad is proved to be significantly improved in comparison with traditional calculation , the reference of calculation of internal force of is provided to other continuous beam in engineering structure , and it is proved that the calculation by using Mathcad software in engineering design is effective, fast and accurate .
