Blast and Impact Loading and Response of Structures
Full Session with Abstracts
In Chapter 5 Design and Analysis Approaches of the Disproportionate Collapse Design Standard, the acceptable procedures for designing buildings to resist disproportionate collapse are specified. The performance criteria from Chapter 4 and the acceptance criteria from Chapter 6 are used to define the initial conditions and acceptable end state of the building design. Alternative load path analysis forms the bulk of Chapter 5 but deemed-to-comply solutions and alternative rational analysis are also allowed; tie forces and specific local resistance are not employed. Component failure and partial structural collapse are defined and debris impact loading from collapse is discussed. Procedures for linear static, nonlinear static and nonlinear dynamic analysis are presented. In this paper, the key aspects of Chapter 5 will be summarized, with insights into the logic and justification used to develop the design and analysis approaches.
