Nudo Coordenadas Barra Nudos L X Y N F F Pulg. Cos Q: Matriz de Rigidez Barra

This document contains information about a structural analysis including node coordinates, member properties, stiffness matrices, and the global structural matrix. It defines 4 nodes, 3 members connecting the nodes, and provides the x and y coordinates of the nodes. It also includes the member lengths, cross sectional properties, and angle between the member and x-axis. Matrices are presented for member displacements, member stiffness, and the overall structural stiffness.
