Engineering Considerations for Lift-slab Construction
註釋In 1987, the collapse of LyyyAmbiance Plaza in Bridgeport, Connecticut demonstrated the need to re-evaluate the engineering of lift-stab construction and determine what is needed to make it safe. This re-evaluation was made by The Task Committee on Lift-Slab Construction of the Technical Council on Forensic Engineering of the American Society of Civil Engineers. Engineering Considerations-for Lift-Slab Construction is based on the work of the task committee; it addresses engineering requirements for lift-slab construction and presents recommendations to engineers, architects, and lift-slab contractors for its safe use. Included are: Concepts and details of various lift-slab systems; Theories on the cause of the LyyyAmbiance Plaza collapse; Discussions on other failures and problems; Considerations and recommendations for lifting collars and lifting equipment; Considerations and recommendations for stability; Recommendations for construction loads; Discussions and recommendations for preventing progressive collapse; and Considerations for planning and execution of lift-slab projects.
