Construction Simulation and Analysis on the Prestress of Suspend-dome structures

摘要

As Jining City integrated gymnasium suspend-dome structure an example, the prestress tension process was carried out finite element simulation analysis by using inverse analysis of construction. The vertical displacement of the control joints and the top rod maximum stress ratio of roof were comparably analyzed with the change of tension position, tension grade and tension sequence. Suggestions were put forward about prestress applying method of suspend-dome structures, in order that similar projects provide reference.
