Full-Process Analysis of Pretensioning Construction of Dalian Gym
As a inclined mega-grid suspend-dome, the prestressing constructi of Dalian gym is very complex. Full-process analysis for the pretensioning scheme should be done before construction. Compared with other pretension methods, a relatively proper scheme of stretching radial cable is put forward and analyzed using construction full-process simulation. The length of active cables without stress is controlled by changing temperature, so pretension is put on cables; Cable tension and removing of temporary support system are simulated using birth and death technology, therefore the structure response of different construction stage and in which stage removing temporary supports is proper are acquired, which provide referenced data for controlling construction safety and precision.
