An Abstract of Finite Element Analysis of Carbon Fiber Reinforced Polymer Emergency Shelters By Nawaf Alsulami Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Master of Science Degree in Civil Engineering The University of Toledo August 2016 This research combines novel lightweight, strong materials, sustainable mobile design solutions, and analysis of extreme wind forces on an emergency shelter. The goal of this research is to develop a versatile, lightweight, strong, and economic emergency shelter which could withstand category five hurricane forces using linear finite element analysis (FEA). The calculation takes into account that the emergency shelter should withstand wind gusts of 157 mile per hour (mph) and missile projectiles. The Main Wind Force Resisting System (MWFRS) and Components and Cladding (C&C) force are used in the wind analysis. The model for the emergency shelter includes composite sandwich panels and steel cable wires. The underlying aim of this analysis is to develop a model to predict how these different parts will react in a static state, bending to the constant or pressure load of the model. In proposing the design and analysis, two materials were taken into consideration. Expanded Polystyrene (EPS) foam core, at a thickness of five inches, and a Carbon Fiber Reinforced Polymer (CFRP) composite with a thickness of 0.047 inches on each side was used as the face sheet material. The total combined thickness of the panel is projected to be 5.09 inches. The advantage to using CFRP over conventional components are measured in vulnerability assessments of both conventional and composite wall panel systems. FEA software package ANSYS 15.0 has been utilized to carry out this design of different models of composite sandwich panel and steel cable structures under the wind pressure loading. The aim of proposing different models is to compare results. The panels of the emergency shelter were modeled by shell as well as solid elements and the results of the panels were compared. In addition, various configurations of anchored steel cables were also investigated. One of the cable configurations was analyzed only with the emergency shelter. The effect of both concentrated and pressure loads were also examined on the wall panels of the emergency shelters. Solid element was selected to model the emergency shelter for future investigation. Regarding the steel cables supporting the emergency shelter, the results demonstrated that the optimal and appropriate positioning of the pre-tensioned loading of cables had significant influence on the performance of the shelter. In the future, this research could direct future applications in relation to steel truss design and configuration. Through combining panels and steel cables, the emergency shelter could sustain the pressure load. The highest deflection detected was 3.2 inches for the Components and Cladding (C&C) model. The results recorded a deflection of 1.1 inches for the Main Wind Force Resisting System (MWFRS) model. These results demonstrated that the emergency shelter design may possibly withstand other types of extreme loading. However, the use of this system in other applications will depend upon the deflection thresholds of the design.
