Abstract

Abstract

Carbon fiber materials have the advantages of light weight, high strength, excellent corrosion resistance and good durability. The carbon fiber reinforced polymen (CFRP) cable dome structure can achieve a long span than the steel cable dome structures do. The prestress level of a cable dome has significant influences on the structural forces and stiffness, so it is necessary to ensure the effective prestress of the members after the tensioning is completed. In this paper, the tensioning influence coefficient of cable dome structures for calculating the tensioning value of active cables was proposed. Based on deformation coordination conditions and the principle of virtual work, the expression of the tensioning influence coefficient of the cable dome structures was derived, and the accuracy of the tensioning influence coefficient was verified by the model test of CFRP cable dome and finite element analysis. In addition, the development law of prestress and vertical displacement of connections under three tensioning schemes were analyzed and discussed, and the selection principle of active cables was proposed.
- CFRP cable dome structures,
- tensioning influence coefficient,
- prestress level,
- tensioning schemes
