Integral Lifting Project of the Qifeng Bridge
Publisher: American Society of Civil Engineers
Abstract: To fulfill the navigation development plan of the Hu-Jia-Shen Channel located on the eastern coast of China, it is necessary to upgrade its width and clearance height. The Qifeng Bridge, an arch bridge over the channel, ...
Comparison of Spatial Interpolation Methods for Extreme Wind Speeds over Canada
Publisher: American Society of Civil Engineers
Abstract: Specified wind speeds or their corresponding wind velocity pressures tabulated in structural design codes are spatially interpolated from the extreme value analysis results of wind records at meteorological stations. ...
Incremental Launching Construction Control of Long Multispan Composite Bridges
Publisher: American Society of Civil Engineers
Abstract: The low stiffness of steel U-shaped girders during incremental launching construction has led to the development of an innovative incremental launching construction method that addresses the special requirements of long, ...
Train-Induced Vibration Control of High-Speed Railway Bridges Equipped with Multiple Tuned Mass Dampers
Publisher: American Society of Civil Engineers
Abstract: This paper deals with the applicability of multiple tuned mass dampers (MTMDs) to suppress train-induced vibration on bridges. A railway bridge is modeled as an Euler-Bernoulli beam and a train is simulated as a series of ...
Thermal Effects on Curved Steel Box Girder Bridges and Their Countermeasures
Publisher: American Society of Civil Engineers
Abstract: Owing to its light self-weight, low heat capacity and large thermal expansion coefficient, the application of the curved steel box girder bridge with small and medium spans has gained popularity for the construction of ...
