Beam Local Stress Prediction Model for Incremental Launching Construction Based on SSA-SVR Algorithm
Publikováno v:
Applied Sciences, Vol 14, Iss 21, p 9645 (2024)
In the multi-point incremental launching construction process, without setting temporary piers at the mid-span, it is difficult to ensure the synchronization of the launching equipment at the same pier, which can easily cause the beam to deviate from

The Dual-Parameter Control of Synchronization in Steel Box Girder Incremental Launching Construction
Publikováno v:
Applied Sciences, Vol 13, Iss 21, p 12074 (2023)
When a steel box girder is constructed using the jacking method, the contact area between the jack and the bottom of the girder is subjected to complex forces, and it is very critical to ensure the local stability of the girder. When the phenomenon o
