【摘要】 本文提出一种框架结构建筑物爆破拆除中求解梁柱结构失稳运动过程的新设想,用分析力学中以能量观点解多自由度系统的拉格朗日方程为基础,辅以差分解法解决梁柱结构牵连运动的问题,为新方法的下一步工作奠定了坚实的基础。更多还原

【Abstract】 An idea of calculation of the process of collapsing movement of beam and column structure in frame construction demolition blasting is advanced in this paper.The novel method,which is based on the Lagrange’s Equation that solves multiple-degree-of-freedom system in terms of energy viewpoint in analytic mechanics,with finite difference solution solving the transport motion of post and beam construction,provides a solid foundation for further research of new method.更多还原
