Structure for Architects: Preventing Partial or Progressive Building Collapse
Course Description: ASCE 7-16, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, provides several design alternatives that architects and engineers can use to reduce the potential for either partial or progressive collapse due to extraordinary events, whether natural or man-made. The minimum design load philosophy of the building code is at odds with some extraordinary events. ASCE 7, Section 2.5, “Load Combinations for Extraordinary Events,” which is incorporated into the IBC, covers such extraordinary events, stating: “Where required by the owner or applicable code, strength and stability shall be checked to ensure that structures are capable of withstanding the effects of extraordinary (i.e., low-probability) events, such as fires, explosions, and vehicular impact without disproportionate collapse.” There are several methods for achieving added safety in both expected and extraordinary events. These include performance-based design (for expected events) and methods for design against partial or progressive collapse (for extraordinary events). In this briefing, we’ll explore methods for design against partial or progressive collapse as found in ASCE 7, Section 1.4.6, “Extraordinary Loads and Events.”
