A new type of configuration analysis method for membrane and cable-membrane structure based on equilibrium of nodal forces
2004
Based on the principle of equilibrium of nodal forces, and using the sub structure method as a numerical analysis tool, a new type of configuration analysis method for membrane, cable membrane is presented in detail in this paper. Using this method, the corresponding equation was educed, and analysis program was developed. Through the classic example (typical catenoid), the convergence and accuracy of the method was proved. This configuration analysis method have the merits of quick convergency and low memory requirement. Through the engineering example, by use of the method of self stress verification, and applying ANSYS as analytical implementation, the result of configuration analysis was verified.
