The Method Of Curved Lever Spatial Rigid Frame Of Reinforced Concrete Hyperbolic Shell Structure Analysis And Program Design

Reinforced concrete shell structure is one of the structures that have the competitive internal force distribution. But the classical solution of shell is difficult and its process is sophisticated, and classical solution of shell structure is few, however, the corresponding and convenient practical program with Reinforced Concrete Structure Design is lack, so the popularization and application of shell is limited. The paper introduces a new simple numerical method for analyzing internal force of shell structure, and an appropriate calculating program was compiled. It is convenient in in-situ project design application.The method of curved lever spatial rigid frame is a new simple and practicable numerical method and it is based on the utility of reinforced concrete shell in practical project and used to analyze internal force of shell structure. This method makes shell structure simplified and discreted into spatial rigid frame structure. That is the shell be divided into orthogonal or oblique crossing girder system which makes up a spatial frame. Then use method of structural mechanics to analyze the curved lever spatial rigid frame structure. When use enough elements, the internal force of the curved lever spatial rigid frame agrees with that of the shell's. By analyzing internal force of the curved lever spatial rigid frame to analyze the internal force of the shell. So it is a simple numerical method for analyzing internal force of shell structure, and can correspond to custom of engineering. It is convenient to apply to engineering problems.The paper introduces the basic theories and several numerical methods of the reinforced concrete shell structure, and emphasizes on representing the theory and program design of the method, Based on Visual Fortran 6.0 compiler, a program on calculating internal force of the discreted structure of shell was compiled. By analyzing and calculating an illustrative example, The paper gives some comment and research on the practical engineering. Based on the experiences of my work, the future research tendency was proposed.
