Abstract:
The paper reviews the various methods to reduce risk from abnormal loads. To limit the occurrence of progressive collapse in large panel residential structures, a philosophy for establishing General Structural Integrity is developed to assure bridging of local damage while maintaining overall stability, thus eliminating the need to design for any particular abnormal load. In this approach, tensile continuity and ductility of the elements, as well as of the overall structure, is provided. The rationale for a minimum tie system consisting of transversal, longitudinal, vertical, and peripheral ties to establish this General Structural Integrity is developed. The objective of this approach is not to afford absolute safety in regard to any exceptional event in any part of every building; rather, the intention is to limit and substantially reduce the general risk of collapse, as compared to that existing if no such measures were taken.
