An Introduction to Engineering the Alternate Path Approach to Prevent Progressive Collapse of Buildings

Book excerpt: Introductory technical guidance for civil engineers and structural engineers interested in design of buildings to mitigate progressive structural collapse under earthquake or explosive loading conditions. Here is what is discussed: 1. INTRODUCTION 2. ALTERNATIVE RATIONAL ANALYSIS 3. LOAD AND RESISTANCE FACTOR DESIGN FOR ALTERNATE PATH METHOD 4. PRIMARY AND SECONDARY COMPONENTS 5. FORCE- AND DEFORMATION-CONTROLLED ACTIONS 6. EXPECTED AND LOWER BOUND STRENGTH 7. MATERIAL PROPERTIES 8. COMPONENT FORCE AND DEFORMATION CAPACITIES 9. REMOVAL OF LOAD-BEARING ELEMENTS FOR THE ALTERNATE PATH METHOD 10. STRUCTURE ACCEPTANCE CRITERIA 11. LINEAR STATIC PROCEDURE 12. NONLINEAR STATIC PROCEDURE 13. NONLINEAR DYNAMIC PROCEDURE 14. DEFINITIONS AND COMMENTARY
