Structural Behaviour Of Steel Frame In Building Fire

Structural Behaviour in Fire and Real Design

A great deal of understanding into the behaviour of composite steel-concrete structures in fire has been developed since the Cardington frame fire tests (UK) 1990s. This has now been broadened so that structures in fire design has a real engineering basis and is not reliant on results from single element testing in the standard furnace. Several projects involving office buildings in the UK and ...

Reliability Analysis of Steel Building Frame Under Earthquake Forces

A simplified fragility analysis of steel building frame is presented which can be used for preliminary estimate of its probability of failure. The risk analysis procedure uses the format of probabilistic Risk Analysis (PRA) and considers band limited white noise at the bed rock as the seismic input. The steel building frame is modeled as a 2D frame and Pushover analysis is then carried out to o...

Structural behaviour during a vertically travelling fire

This study considers a multi-storey composite frame subject to a fire which travels vertically between three floors. Previousworkhas analysed the behaviour of this structurewhen subject to simultaneous fires on three floors. It highlighted the importance of the cooling regime adopted and the relative axial stiffness of the steel beams to the overall behaviour of the structure. This paper extend...

Computation of Structural Fire Resistance of Steel Sections

The main object of this study is to compute the structural fire resistance for several steel members under different loading conditions. This is done in chapter 4 using two advanced calculation models. Chapter 1 contains prescriptions according to European codes, needed for this research. In Chapter 2 the notion of structural fire resistance is explained and also information about the types of ...
