Abstract

Abstract

The hollow foundation is applied to the super-height prefabricated concrete tower of onshore wind power, whose stress characteristics are different from post-tensioned prestressed concrete beam structure. In this paper, a tensioning method of two symmetrical cable by stressed synchronously is proposed. At the same time, the finite element analysis software is used to simulate the different tension schemes by comparing the change of cable force and the stress response of the structure in each tension stage, and compare the maximum tensile stress value of the tower structure and the uniformity of the stress distribution. Comprehensive evaluation has carried out on each scheme to determine the a more reasonable tensioning method to guide the site construction, so as to promote the widespread application of this new type of foundation on wind power and other similar structures in future.
