Sažetak
Based on the similarity of the equation systems of the displacement method and the force density method, computer code for solving frame structures by displacement method is modified to implement force density method. Namely, force density in the homonymous method is analogous to stiffness coefficient of the frame element in the displacement method. In both methods the connections between nodes can be resolved in the same way. Therefore the stiffness matrix in the displacement method has the same structure as the system matrix in the force density method. The unknowns in displacement method are displacement components of nodes while the unknowns in force density method are nodal coordinates. Examples of the application of the written programme include single step solutions which are compared with similar physical model and minimal nets.
