Un cable está cargado por medio de una carga uniforme. This causes the deformed shape in the form of the circular segment. Determine the equilibrium force of the cable to obtain the given sag of the cable. The add-on module RF-FORM-FINDING is used for this purpose. Elastic deformations are neglected both in RF-FORM-FINDING and in the analytical solution; self-weight is also neglected in this example.
Una estructura se compone de cuatro barras de celosía, que están incrustadas en apoyos de articulación. The structure is loaded by a concentrated force and alternatively by imposed nodal deformation over the critical limit point, when snap-through occurs. Imposed nodal deformation is used in RFEM 5 and RSTAB 8 to obtain the full equilibrium path of the snap-through. The self-weight is neglected in this example. Determine the relationship between the actual loading force and the deflection, considering large deformation analysis. Evaluate the load factor at given deflections.
Un cable muy rígido está suspendido entre dos apoyos. Determine the equilibrium shape of the cable (the catenary), consider the gravitational acceleration, and neglect the stiffness of the cable. Verify the position of the cable at the given test points.
A structure is made of two trusses of unequal length, which are embedded into the hinge supports. The structure is loaded by concentrated force. Se omite el peso propio. Determine the relationship between the loading force and the deflection, considering large deformations.
Un cable o membrana de acero con pasadores en ambos extremos se carga mediante una carga distribuida. Neglecting its self-weight, determine the maximum deflection of the structure using the large deformation analysis.
