在本文中,作者批判了德国H.Marcus提出而被一些国家采用多年的双向板简化计算方法,并根据弹性理论基本概念提出一项新的计算方法。该法的力学概念清晰。还可用以计算前法所不能计算的其它情况的双向板。对筒壳计算,作者批判了苏联В.Э.Власов的简化计算方法,并提出用简单的材料力学方法来计算这一较复杂的弹性理论空间问题。此外还利用扭矩和横向弯矩的有限差分关系,解决了一般简化方法所未曾解决的中长筒壳计算问题。
In this article, the author criticizes H. Marcus’s proposal by Germany and has been used by many countries for years to simplify calculation methods for two-way boards, and propose a new calculation method based on the basic concepts of elasticity theory. The mechanics of the law are clear. It can also be used to calculate two-way boards that cannot be calculated by the previous method. For cartridge calculations, the author criticized the simplified calculation method of the Soviet Union В.Э. Власов and proposed a simple material mechanics method to calculate this more complex elastic theory space problem. In addition, the finite-difference relationship between torque and lateral bending moments is also used to solve the problem of medium and long cylinder shells that have not been solved by the general simplified method.
