Behavior of portal frames of steel hollow sections exposed to fire

Response of Fire Exposed Steel Bridge Girders

Predicting the mechanical behavior of steel frames exposed to elevated temperatures using artificial neural networks

The structural behavior fire-resistant steel is essential; fire-resistant steel is proven to have higher strength at elevated temperature than that of conventional steel. Also, the requirement of fire protection in the fire-resisting steel can be relaxed as compared with conventional steel structures. However, the design criteria for the application of the fire-resisting steel in steel columns ...

Numerical Analysis of Cyclic Behavior of Beam-To-Column Bolted Connections in Steel Frames

This article considers the seismic behavior of beam-to-column joints in steel frames for different bolt arrangements by using of finite element modeling. As the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. Four different specimens have been analyzed. These models had some differences such as bolt arrangement and the presence or a...

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 ...

Bending Fatigue Tests and Finite Element Models of Steel Rectangular Hollow Sections [SRHS]

The Welding in cold formed areas is not only an open question for statically loaded sections (brittle fracture) but also for dynamically loaded structures (fatigue resistance). A lot of structures are subjected to dynamic loadings and unfortunately very little information about the influence of welding in the cold formed areas on fatigue resistance is available. In order to establish the fatigu...
