Progressive Collapse Analysis and Design Guidelines

Analysis and Design Guidelines for New Federal Office Buildings and Major Modernization Projects” to ensure that the potential for progressive collapse is addressed in the design, planning and construction of new buildings and major renovation projects. Mr. Bruce Hall, P.E., of the Office of the Chief Architect, initiated this work in 1999 and

Reliability Assessment of Load Testing for Concrete Buildings

provide requirements and guidelines for load testing, there are distinct differences in the test load magnitudes, loading protocols, and acceptance criteria. The primary purpose of this research was to develop an understanding of reliability-based load testing safety concepts in the context of the current provisions of ACI 437.2-13 and ACI

Reliability-based design of FRP flexural strengthened

In the existing design guidelines, ACI 440.2R 2017 follows the concept of resistance reduction factor while GB 50608 2010 and fib T5.1 2019 are the representatives for the partial safety factor format. Notably, an additional reduction factor (ϕ f) is recommended in the American Concrete Institute (ACI) guidelines to consider the uncertainty inherent in FRP systems .

Reliability-Based Load Criteria for Structural Design

The reliability-based design of concrete structures requires the consideration of the following three components: (a) loads, (b) structural strength, and (c) methods of reliability analysis. There are two primary approaches for reliability based design: (a) direct reliability-based design and (b) Load and Resistance Factor Design (LRFD). The

Reliability, Lifetime and Safety Factors

As a design requirement, a minimum safety factor (or maxi-mum exposure) is given. Some of the standardized methods for bearings calculation, like ISO 281 (Ref.3), directly deliver an achievable life out of the loads. In the case of the bearings, the loads are the forces in radial and axial direction.
