ASCE/SEI Advancements in Structural Fire Engineering

<p>Advancements put forth by the Structural Engineering Institute (SEI) of ASCE are paving the way for a regulated engineered alternative to the long‐standing archaic requirements for structural fire design. For the past century, project stakeholders have tolerated a strikingly inefficient and amorphous system for protecting structures from uncontrolled fire. Traditionally, fire protection is prescribed for structures after they have been optimized for ambient design loads (i.e., gravity, wind, seismic, and others), with no explicit consideration of structural fire performance. Accordingly, the vulnerability of buildings to structural failure from uncontrolled fire is presumably variable across different jurisdictions, which have varying structural design requirements for ambient loads. Also, structural engineers are often absent from the structural fire protection design process entirely.</p><p>In conjunction with new provisions in Appendix E of Minimum Design Loads and Associated Criterial for Buildings and Other Structures (ASCE/SEI 7‐16), a first‐of‐its‐kind ASCE/SEI Manual of Practice 138: Structural Fire Engineering, has been developed to provide structural engineers a baseline level of guidance to practice structural fire engineering. Also, ASCE/SEI has partnered with the Charles Pankow Foundation to conduct an ambitious project meant to showcase this new technology to the industry. Advancing the adoption of performance‐based structural fire engineering within the AEC industry will benefit public safety while delivering more efficient and economic building designs.</p>

Reliable and accurate measurements of temperature and strain in structures subjected to fire can be difficult to obtain using traditional sensing technologies based on electrical signals. Fiber optic sensors, which are based on light signals, solve many of the problems of monitoring structures in high temperature environments; however, they present their own challenges. This paper, which is intended for structural engineers new to fiber optic sensors, reviews various fiber optic sensors that have been used to make measurements in structure fires, including the sensing principles, fabrication, key characteristics, and recently-reported applications. Three categories of fiber optic sensors are reviewed: Grating-based sensors, interferometer sensors, and distributed sensors.

The British Standards and the Eurocodes both cover the design of steel structures in fire. These provide designers with the opportunity to exploit the properties of structural steel to its maximum capacity in the fire limit state, termed Structural Fire Engineering. This allows fire protection measures to be integrated into structural design as part of the passive fire protection specification. If used effectively in the specification process it can bring significant benefits to the project, including robust and safe designs, quantified structural performance and cost savings.The suitability of a member in a structural design is generally governed by serviceability limitations such as deflection. Generally this approach provides a conservative working stress for the steel sections of approximately 50% of their overall capacity. Within the UK, this simplified approach led to the development of prescribed limiting steel temperatures of 550°C for columns and 620°C for beams.Best-practice industry guidance published in the UK encourages designers to specify a limiting steel temperature together with the fire resistance period as part of the overall steelwork specification. Passive fire protection is generally specified post design-stage at a contractor or applicator level and sometimes very little is known about the limiting steel temperature.This paper provides an overview of the fire protection specification and provides advice on structural fire engineering to determine a limiting steel temperature and the benefits that can be gained from doing so. The paper highlights how supplier expertise in fire engineering approaches and product performance knowledge can bring value to a design and play an important role in providing safe, cost effective and compliant solutions.
