چکیده مقاله :
This paper presents an Auto Redundant Technique for analysis of grid with curved members.This technique is based on the force method, but in the technique choice of the redundant iscompletely eliminated. The analysis technique is found very effective, accurate andprogrammable. A comprehensive C++ program has been developed to compute internalforces at the end of each member of the grid for different load cases and their combinations.Presently in this paper analysis of grid is carried out with fixed support when it is subjected toconcentrated point load, twisting moment, bending moment, full/partial uniformly distributedload and full/partial uniformly varying load. In this technique, any number of load cases canbe accommodated without creating any additional node(s) on the member. The power of theanalysis procedure is effectively demonstrated through the solution of one benchmarkproblem. The results obtained through the program for complementary load cases arecompared with the results from analysis software and are found to match.
