This book was released on 2015 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiber reinforced polymer (FRP) honeycomb panels offer an efficient and rapid replacement to concrete decks. The system consists of FRP honeycomb sandwich panels with adequate guardrails. Although FRP bridge deck panels have already been designed and used over the past several years on a number of through truss bridges, they could not be used on steel girder bridges until approved crashworthy bridge railing attachments could be validated. Two systems have been successfully crash tested, one with steel thrie beams/guardrails on steel posts and the other with concrete barriers. Both systems are now ready for use on temporary/detour bridges, or as permanent deck replacement allowing higher live load while keeping the existing steel girders and substructure. The light weight of FRP honeycomb panels (about 75% lighter than concrete) allows heavier truck loads, while keeping the existing girders and substructure without compromising the safety of the public. The roadway can be made wider by increasing the overhangs, thus allowing for wider farm equipment on narrow bridges in rural areas. The replacement of the concrete deck using this system may be completed in a matter of a few days, or even hours, as opposed to several months when using the conventional methods.

This book was released on 2015 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A fiber-reinforced, polyurethane foam core was developed, tested, and evaluated as a possible replacement for the costly honeycomb core that is currently used to manufacture fiber-reinforced polymer (FRP) bridge deck panels. Replacing these panels would reduce both initial production costs and construction times while also enhancing structural performance. Experimental, numerical, and analytical investigations were each conducted. Three different polyurethane foam (PU) configurations were used for the inner core during the study's first phase. These configurations consisted of a high-density PU foam (Type 1), a gridwork of thin, interconnecting, glass fiber/resin webs that formed a bidirectional gridwork in-filled with a low-density PU foam (Type 2), and a trapezoidal-shaped, low-density PU foam that utilized E-glass web layers (Type 3). Based on the experimental results of this phase, the Type 3 core was recommended to move forward to the second phase of the study, where a larger-scale version of the Type 3, namely "−mid-scale panels," were tested both statically and dynamically. Analytical models and finite element analysis (FEA) were each conducted during a third phase. Analytical models were used to predict critical facesheet wrinkling that had been observed during phase two. A three-dimensional model using ABAQUS was developed to analyze each panel's behavior. A parametric study considering a wide variety of parameters was also conducted to further evaluate the behavior of the prototype panel. The fourth phase of this research investigated the performance of Type 3 panels under exposure to various environmental conditions to duplicate seasonal effects in Midwestern states. The results gathered from these four phases showed that the proposed Type 3 panel is a cost effective alternative to both honeycomb and reinforced concrete bridge decks."--Abstract, page iv.

Download or read book Fatigue Evaluation of Multiple Fiber-Reinforced Polymer Bridge Deck Systems Over Existing Girders Phase II Report written by and published by . This book was released on 2003 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decks manufactured with fiber-reinforced polymer (FRP) composite materials are used in highway bridges. A performance evaluation of FRP composite decks subjected to simulated traffic loads that induce repetitive stress cycles under extremely high and low temperature is presented. Fatigue testing of three FRP composite bridge deck prototypes and one FRP-concrete hybrid bridge deck prototype under two extreme temperature conditions: -30 C ( -22 F), and 50 C (122 F) was conducted. The fatigue response of the deck prototypes was correlated with the baseline performance of a conventional reinforced concrete deck subjected to similar test conditions. Design loads were applied simultaneously at two points using servo-controlled hydraulic actuators specially designed and fabricated to perform under extreme temperatures. Quasi-static load-deflection and load-strain characteristics were determined at predetermined fatigue cycle levels. No significant distress was observed in any of the composite deck prototypes during ten million load cycles. The effects of extreme temperatures and accumulated load cycles on the load-deflection and load-strain response of FRP composite and FRP-concrete hybrid bridge decks are discussed based on the experimental results.

Available in PDF, EPUB and Kindle. Book excerpt: Fibre reinforced polymer (FRP) composites are used in almost every type of advanced engineering structure, with their usage ranging from aircraft, helicopters and spacecraft through to boats, ships and offshore platforms and to automobiles, sports goods, chemical processing equipment and civil infrastructure such as bridges and buildlings. The usage of FRP composites continues to grow at an impessive rate as these materials are used more in their existing markets and become established in relatively new markets such as biomedical devices and civil structures. A key factor driving the increased applications of composites over the recent years is the development of new advanced forms of FRP materials. This includes developments in high performance resin systems and new styles of reinforcement, such as carbon nanotubes and nanoparticles. This book provides an up-to-date account of the fabrication, mechanical properties, delamination resistance, impact tolerance and applications of 3D FRP composites.

This book was released on 2012-12-06 with total page 858 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fourth Conference on Fibrous Composites in Structural Design was a successor to the First-to-Third Conferences on Fibrous Composites in Flight Vehicle Design sponsored by the Air Force (First and Second Conferences, September 1973 and May 1974) and by NASA (Third Conference, November 1975) which were aimed at focusing national attention on flight vehicle applications of a new class of fiber reinforced materials, the advanced com posites, which afforded weight savings and other advantages which had not been previously available. The Fourth Conference, held at San Diego, California, 14-17 November 1978, was the fi rst of these conferences to be jointly sponsored by the Army, Navy and Ai r Force together with NASA, as well as being the first to give attention to non-aerospace applications of fiber reinforced composites. While the design technology for aerospace applications has reached a state of relative maturity, other areas of application such as mi litary bridging, flywheel energy storage systems, ship and surface vessel components and ground vehicle components are in an early stage of development, and it was an important objective to pinpoint where careful attention to structural design was needed in such applications to achfeve maximum structural performance payoff together with a high level of reliability and attractive economics.

Book Synopsis Columbia Crew Survival Investigation Report by : Nasa
Download or read book Columbia Crew Survival Investigation Report written by Nasa and published by PDQ Press. This book was released on 2009 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA commissioned the Columbia Accident Investigation Board (CAIB) to conduct a thorough review of both the technical and the organizational causes of the loss of the Space Shuttle Columbia and her crew on February 1, 2003. The accident investigation that followed determined that a large piece of insulating foam from Columbia's external tank (ET) had come off during ascent and struck the leading edge of the left wing, causing critical damage. The damage was undetected during the mission. The Columbia accident was not survivable. After the Columbia Accident Investigation Board (CAIB) investigation regarding the cause of the accident was completed, further consideration produced the question of whether there were lessons to be learned about how to improve crew survival in the future. This investigation was performed with the belief that a comprehensive, respectful investigation could provide knowledge that can protect future crews in the worldwide community of human space flight. Additionally, in the course of the investigation, several areas of research were identified that could improve our understanding of both nominal space flight and future spacecraft accidents. This report is the first comprehensive, publicly available accident investigation report addressing crew survival for a human spacecraft mishap, and it provides key information for future crew survival investigations. The results of this investigation are intended to add meaning to the sacrifice of the crew's lives by making space flight safer for all future generations.
