Design and Construction of Large-Panel Concrete Structures. Report number 2. Philosophy of Structural Response to Normal and Abnormal Loads,

摘要

Response of large panel structures to both normal loading and abnormal loadings is discussed qualitatively. Conditions particular to these structures which can affect their behavior are identified. Methods for reducing the risk of progressive collapse from abnormal loads are examined. A philosophy of design based on bridging local damage is introduced which emphasizes continuity and ductility within and accross connections. A methodology is developed to be used in establishing minimum detailing criteria to ensure integrity of the structure. In this general structural integrity approach code requirements for minimum ties will be provided to assure an alternative path for the load in the event of a local failure of a primary load bearing element. Design considerations for both individual elements and connections are discussed conceptually.
