- Building Performance Targets per ASCE 7-16, FEMA P-695, and NIST - ideCAD
FEMA P-695 presents a detailed methodology for determining the collapse probability of classes of buildings Several case studies have used the methodology to benchmark the performance of modern buildings, with results reported in FEMA P-695 (2009) and NIST (2010)
- How are Building Risk Categories Assigned? – The StructEd
By assigning Risk Categories, the building code calls out higher minimum requirements for buildings with the potential to greatly impact large numbers of people Engineers and architects can use those same Risk Category designations to help communicate the design needs throughout the entire design team, ensuring everyone is on the same page
- Buildings - National Institute of Standards and Technology
Risk categories rank building 95 performance with a progression of the anticipated seriousness of the consequence of failure from lowest 96 risk to human life (Risk Category I) to the highest (Risk Category IV)
- Probability-Based Load Criteria for Structural Design - NIST
Structural codes are linked to computational methods of safety assessment, and their primary purpose is to manage risk and maintain safety of buildings, bridges and other facilities at socially acceptable levels Until the 1960s, the safety criteria in structural codes were based on allowable stress principles
- The Performance Basis for ASCE 7-10 - AISC
the building code for many years as a means of determining required design conservatism, to “Risk Category ” This change acknowledges that the purpose of these categories is to regu-late the acceptable risk of failure for buildings, and that this depends on other factors than just the structure’s occupancy,
- Risk Categorization in Accordance with ANSI TIA and the
Following are the definitions of risk categories, first per ANSI TIA-222-H (Rev H) Table 2-1, followed by the definitions from the 2018 International Building Code (IBC) RISK CATEGORY I ANSI TIA-222-H: Structures that due to use or loca-tion represent a low risk to human life and or damage to surrounding facilities in the event of failure
- Target reliability of new and existing structures - A general framework . . .
In this paper a general framework is given in order to make the reliability index independent of the design working life and to provide guidance for specification of the target reliability level for different situations The study is based on probabilistic economic optimization
- Probabilistic risk analysis and building performance simulations . . .
The concept of risk and risk analysis requires two steps, quantifying the probability and the consequence of failure, where failure is defined as unwanted events Using a probabilistic approach to quantify and predict the EP of buildings enables using risk to evaluate the building design
