Abstract

At present, rarely research is done about the loading process of cable net curtain wall with spring mechanism, therefore, how to select the spring stiffness at the cable end and what role the spring play in the process of loading become the very concern for curtain wall designers. Therefore, based on the early cable net computing model of a building-Beijing Olympic Project Tower 3, the influence of spring stiffness on the force performance of cable net is analyzed with the condition that the external load and cable prestress unchanged. It shows that: under the same external load, the smaller the spring stiffness is, the lower the axial force of vertical cable and the vertical bearing reaction force is, which is better to meet the bearing capacity of vertical cable and the main structure connected with it, and increase the axial force of horizontal cable, the maximum deflection and the initial prestress of the vertical cable; the smaller the spring stiffness is, the more uneven the internal force of the vertical cable is, which is only influenced by the gravity load taken by vertical cable, and has no relation with the initial prestress and the change of deflection; the smaller the spring stiffness, the larger part the spring take in the whole bearing process.
