Behaviour of high strength steel moment joints

The design of joints to European standard EN 1993 within the semi-continuous/partially restrained philosophy is restricted to steel grades up to S460. With the recent development of high performance steels, the need for these restrictions should be revisited. The semicontinuous joint modelling can be adopted as long as the joint develops...

Use of High Strength Steel Grades for Economical Bridge Design

Bridges offer great potential for the use of high strength steel grades (HSS). The main advantages are generally a result of reduced weight and cross-sectional dimensions. Design stresses can be increased and plate thickness may be reduced, resulting in significant weight savings. Reduced plate thickness can also save on welding costs as well as...

Behaviour of High Strength Steel Endplate Connections in Fire and after Fire

The aim of this research is to reveal more information and understanding on behaviour and failure mechanisms of high strength steel endplate connections (combining high strength steel endplates with either mild steel or high strength steel beams and columns in endplate connections) in fire and after fire, for an effective application of high...

Optimisation of plate girders

In many steel structures like buildings, industrial halls and bridges, standardized hot-rolled sections are used. These sections are divided into specific types in Europe and similar profiles in the USA. The range of hot-rolled sections is limited and therefore fabricated plate girders are used when the standard hot-rolled sections do not meet...

Material Factors for High Strength Rectangular Hollow Section X joints

An increasing trend is occurring in the use of high strength steel (HSS) in tubular joints. Reason for this trend is the high yield strength of HSS which leads to reduced weights and costs. Characteristic for HSS is the reduced ductility in comparison to normal steels. Therefore, Eurocode 3 part 1-8 (2020) recommends material reduction factors ...
