Study on General Total Stiffness Matrix of Plane Multi-Storied Truss
This paper proposes a new description method of truss structure based on adjacent matrix and the expression of element stiffness matrix (ESM) containing the joint number. Furthermore a procedure is also given for obtaining a general total stiffness matrix (GTSM) by using the method of large domain transformation matrix (LDTM). GTSM can reduce the difficulty in designing variable geometry trusses.
