Performance-Based Design Of Rc Beams Using An Equivalent Standard Fire, Robert T. Kuehnen, Maged Youssef, Salah El-Din F. El-Fitiany

Civil and Environmental Engineering Publications

The design of buildings for fire events is essential to ensure occupant safety. Supplementary to simple prescriptive methods, performance-based fire design can be applied to achieve a greater level of safety and flexibility in design. To make performance-based fire design more accessible, a time equivalent method can be used to approximate a given natural fire event using a single standard fire with a specific duration. Doing so, allows for natural fire events to be linked to the wealth of existing data from the standard fire scenario.

In this paper, the use of an existing time equivalent method is reviewed and …

Practical Method To Predict The Axial Capacity Of Rc Columns Exposed To Standard Fire, Salah El-Din F. El-Fitiany, Maged Youssef

Civil and Environmental Engineering Publications

Purpose

Existing analytical methods for the evaluation of fire safety of reinforced concrete (RC) structures require extensive knowledge of heat transfer calculations and the finite element method. This paper aims to propose a rational method to predict the axial capacity of RC columns exposed to standard fire.

Design/methodology/approach

The average temperature distribution along the section height is first predicted for a specific fire scenario. The corresponding distribution of the reduced concrete strength is then integrated to develop expressions to calculate the axial capacity of RC columns exposed to fire from four faces.

Findings

These expressions provide structural engineers with a …
