In this study, a new mixture design methodology based on the 4-parameters compressible packing model (CPM) of Packing Density Theory was proposed to satisfy the specific performance criteria of high performance concrete for prestressed concrete bridge construction. Iterative algorithms were developed to determine the parameter of critical cavity si...

This paper deals with a quantitative risk analysis method for V-shaped piers during the construction process, by using the artificial neuron network technique. Regarding the finite element analysis results as a neural network training sample data, an invisible mapping relationship between the basic variables and the structural response is establish...

To solve the complex problem of V-shaped pier's stress analysis based on the butterfly arch continuous girder bridge in Heihe, China, using finite element analysis method, this paper deals with the distribution rule of stress in V-shaped pier's crucial parts. As the pier has an intersection angle of 115.6 degrees, space analysis model of the V pier...

Based on the butterfly arch continuous girder bridge in HeiHe, China, this paper mainly deals with a quantitative risk analysis for V-shaped pier during the construction process, by using Analytic Hierarchy Process - Grey Correlation Analysis method. Firstly, hierarchical model of risk analysis is established, and structural property is identified...
