“Surviving is a true blessing that few get to experience.” Being strapped in the seat of a plane as it plunges into a nosedive midair is everyone’s worst nightmare. Bracing for Impact’s compilers and contributors know. They have both lived out that fear and survived, albeit badly hurt, in their own plane crashes. In this collection of true-life survivor tales, people from all walks of life—a freelance writer, a crew member of the Lynyrd Skynyrd band, a naval flight surgeon, a teenager, and a newlywed on her honeymoon, among others—recount their traumatic narrow escapes as engines stalled, fuel ran out, hazardous weather conditions descended, and landings did not go according to plan. In the face of death, as life flashed before their eyes—or not, as some wryly note—these survivors encountered the terrific split of before and after the crash. Their lives, though preserved, would change forever. Perhaps more significant than the crash itself is how each story plays out in the aftermath of the ordeal. In heart-wrenching, unrelenting honesty, these stories explore the wide spectrum of impacts on survivors—ranging from debilitating fear, post-traumatic stress disorder, and substance abuse, to a renewed sense of urgency, where survivors swear to live each day to the fullest and rededicate their lives to helping others. Including the 1977 story of the Lynyrd Skynyrd plane crash that killed lead singer Ronnie Van Zant, guitarist Steve Gaines, and vocalist Cassie Gaines, Bracing for Impact is as much a horrific account of air disasters as it is a celebration and recognition of the people who survived them. Fans of the 2016 Clint Eastwood film Sully starring Tom Hanks will enjoy this edge-of-your-seat read!

Impact of Overhang Construction on Girder Design

Economical constraints on the design of bridges usually necessitate the use of as few girders as possible across the bridge width. The girders are typically uniformly spaced transversely with the deck extending past the fascia girders, thereby resulting in an overhang. While designers commonly employ rules of thumb with regard to the geometry of the overhang, these rules of thumb generally address only the deck in-service strength and deflection requirements, and the effect due to construction load is not considered. In particular, the impact of the overhang on fascia girder behavior during construction is not well understood. Overhang construction often leads to a torsional load on the girder system that can lead to problems in steel and concrete girder bridges during construction. The main issue with concrete girder bridges is excessive lateral rotation in the fascia girder, which can cause potential problems of construction safety and maintenance. Field problems on concrete bridges have been reported in the state of Texas where the fascia girders experienced excessive rotation during construction. For steel girder bridges, the unbalanced overhang loading can lead to both local and global instability. Locally, the overhang brackets often exert a large force on the web plate that can distort the web and increase the magnitude of the plate imperfection. Global stability problems have occurred primarily on bridge widening projects where a few girders are added to an existing bridge system. The girders in the widening are usually isolated from the existing bridge and the unbalanced load from the overhang can cause excessive twist that intensifies the global stability of the girder system. The objective of this study was to improve the understanding of the bridge behavior due to the unbalanced loading from the overhangs and to identify critical factors affecting the girder behavior. The study was also aimed at developing simple design methodologies and design recommendations for overhang construction. The research included field monitoring, laboratory tests, and parametric finite element analyses. The data from the field monitoring and laboratory tests were used to validate finite element models for both concrete and steel girder bridges. Based on the validated models, detailed parametric studies were conducted to investigate the effects of the unbalanced loading. Results from the parametric studies were used to identify the geometries of girder systems that are prone to problems with the overhangs as well as to provide design suggestions. In addition, a closed-form solution for lateral rotation in the fascia girder in a concrete girder bridge was derived using a rigid-body model, and was used to develop design methodology and design recommendations for overhang construction.

The response of structures and structural elements to explosive shock or high speed impact is of growing interest to scientists, research engineers and designers throughout the world. Attacks on civil and military buildings, bridges and transport vehicles by terrorists mean that more attention has to be given at the design stage to the effects of explosions and impact, and to high speed penetration of attack weapons. This book brings together the experience of specialists in the behaviour of concrete and metal structures, both above and below the ground, to actions of blast, penetration and high speed collisions.
