RISCracking Mechanism and Simplified Design Method for Bottom Flange in Prestressed Concrete Box Girder Bridge
Publisher: American Society of Civil Engineers
Abstract: Serious cracking has occurred frequently in the bottom flange of box girders during construction in recent years. This paper aims at studying the cracking mechanism and countermeasures. The stress field in the bottom flange ...
Fluid–Vehicle–Tunnel Coupled Vibration Analysis of a Submerged Floating Tunnel Based on a Wake Oscillator Model
Publisher: ASCE
Abstract: The submerged floating tunnel (SFT) is a newly developed traffic structure for crossing the long waterway. On the basis of the vehicle–tunnel coupled vibration, the vortex-induced effect of the SFT in the water flow field ...
