“Time-varying reliability analysis of long-span continuous rigid frame bridge under cantilever construction stage based on the monitored strain data”
Today recommendation
During the construction of bridge engineering, quality accidents have occurred sometimes. For example, two collapse accidents happened on Quebec Bridge during construction in Canada, of which the span is 548.46 meters. Therefore, monitoring and controlling of the bridge from the beginning of construction is an important methodology to ensure the bridge construction safety and quality, especially the long-span bridges. Today, construction monitoring is an essential part of the modern large-span bridges in the construction stage, and its role is to ensure the safety evaluation for the construction quality and safety of the bridge. Because of the influence of many factors (such as: non uniformity of the material itself, non stability of material properties, the changing of temperature and humidity etc.) and the changing of structure shape, loads and resistance in the construction stage, it makes the internal force safety assessment by the monitoring information of the continuous rigid frame bridge become the difficult parts.
