Civil, Construction and Environmental Engineering

The Department of Civil, Construction, and Environmental Engineering seeks to apply knowledge of the laws, forces, and materials of nature to the construction, planning, design, and maintenance of public and private facilities. The Civil Engineering option focuses on transportation systems, bridges, roads, water systems and dams, pollution control, etc. The Construction Engineering option focuses on construction project engineering, design, management, etc.

The Department of Civil Engineering was founded in 1889. In 1987 it changed its name to the Department of Civil and Construction Engineering. In 2003 it changed its name to the Department of Civil, Construction and Environmental Engineering.

The Federal Aviation Administration (FAA) has recognized for some time that its current rigid 44 pavement design model, involving a single slab loaded at one edge by a single aircraft gear, is 45 inadequate to account for top-down cracking. Thus, one of the major observed failure modes for 46 rigid pavements is poorly represented in the FAA Rigid and Flexible Iterative Elastic Layer 47 Design (FAARFIELD) program. A research version of the FAARFIELD design software has 48 been developed (FAARFIELD 2.0), in which the single-slab three-dimensional finite element 49 (3D-FE) response model is replaced by a 4-slab 3D-FE model with initial temperature curling to 50 produce reasonable thickness designs accounting for top-down cracking behavior. However, the 51 long and unpredictable run times associated with the 4-slab model and curled slabs make routine 52 design with this model impractical. In this paper, use of artificial intelligence (AI)-based 53 alternatives such as artificial neural networks (ANNs) with potential for producing accurate 54 stress predictions in a fraction of the time needed to perform a full 3D-FE computation has been 55 investigated. In the development of ANN models, a synthetic database of FAARFIELD input- 56 output pairs representing a number of realistic scenarios were developed. Moreover, ANN 57 models for only mechanical and simultaneous mechanical and thermal loading cases were 58 developed and accuracy predictions of these models were documented. It was observed that very 59 high accuracies were achieved in predicting pavement responses for all cases investigated.
