Sensitivity analysis and calibration of the alligator cracking model in the mechanistic-empirical pavement design guide using regional data
… cracking model uses traffic, material and structural data along with local and global calibration factors to calculate the number of axles to failure and the damage index. Both of which are further used to calculate the fatigue cracking in the pavement with the help of regression …

Impact of structure, material properties, temperature curling, and trafficking on load transfer efficiency
… induced slab curling can have on joint LTE (S). Analysis is conducted from full scale accelerated pavement test data from the National Airport Pavement Test Facility (NAPTF) operated by the Federal Aviation Administration (FAA). LTE (S) is determined through strain measurements from gages …

Study of load transfer efficiency of airfield rigid pavement joints based on stresses and deflections
… also determined using 2D and 3D-finite element analysis programs. The pavement configuration and the aircraft gear similar to those at NAPTF was simulated in a 2Dfinite element program JSLAB and LTE (S) under static load was determined and compared with that obtained under the moving loads. …

EFFICIENT SOLUTION METHODS FOR NONLINEAR FINITE ELEMENT ANALYSIS (DESIGN, GEOMETRIC MATERIAL, POST-BUCKLING, STRUCTURAL, MECHANICS, NUMERICAL).
… the existing solution algorithms for nonlinear structural analysis using the finite element formulation is presented. Arc-length methods, which facilitate the tracing of the load-configuration path beyond limit points, are systematically examined. Specific emphasis is focussed on obtaining the …

Fine-tuning a domain-specific language model for truss structural analysis
… vison-language and large-language for truss structural analysis. General-purpose AI models often struggle with engineering-specific problems due to insufficient domain knowledge. To address this, we propose a hybrid workflow for truss analysis via the stiffness method as a case study. The …

Influence of moving load, structure, temperature gradient, and wheel configuration on load transfer efficiency
… and three-dimensional finite element-based structural analysis developed to calculate design thicknesses for airfield pavements. The design procedure assumes constant stress-based load transfer efficiency (LTE (S)), of 25% at the joints. Variations in environmental conditions, loading …

Verification of the dissipated energy based fatigue model using field data
Damage can be limited to the top layer in perpetual pavements through the use of a very thick surface layer or a binder-rich intermediate layer. To achieve this goal, tensile strains at the bottom of the top hot-mix asphalt (HMA) layer must be limited to below a certain value known as the fatigue …

Developments in the theory and applications of the variability response function concept
Uncertainty quantification in Civil Engineering applications is crucial to the decision making process in the analysis, design, and retrofitting of infrastructure. The consensus amongst researchers is that deterministic approaches to problem solving can lead to very misleading results, and the …

The application of the law of virtual work in the solution of civil engineering structures
… purpose of this thesis is to explore the civil engineering application of the law of virtual work to the determination of defelections, shears, bending stresses in truss structures, beams, structures subjected to both direct stress and bending, and indeterminate structures, and further to give …

Structural assesment of joints in satellites using guided waves
The intention of the Air Forces Responsive Space Initiative Project is to develop procedures and technologies necessary to produce a satellite within six days from the initial order. Modular satellite designs have been proposed to help streamline the process of preparing a satellite for deployment. …

2-D Modeling of Electromagnetic Waves with Vibrating Conducting and Dielectric Objects
This Thesis provides an analysis of the interaction of electromagnetic pulses with vibrating conducting and dielectric objects. Two-dimensional full-vector Maxwells equations finite-difference time-domain (FDTD) models are employed that include total-field scattered-field incident plane wave source …

Estudio analítico y numérico de la capacidad portante de zapatas corridas sobre taludes
Diversos proyectos de ingeniería, tales como edificios, torres de alta tensión y estribos de puentes, se cimientan en zonas adyacentes a un talud. Cuando ello ocurre, el comportamiento de la cimentación se ve afectado por la presencia del desnivel, que modifica su capacidad portante y afecta el …
