Abstract

The calculation of the loadbearing capacity of hollow section joints using the design formulas according to EN 1993‐1‐8 assumes full‐strength welded connections if the non‐linear stress distribution over the circumference is not covered by calculation. Sufficient ductility in the connections ensures a plastic redistribution capacity within each joint. In the case of hollow section structures made of high‐strength steels, it becomes more difficult to meet the requirement for full‐strength welds as the yield strength of the base material increases.

高强度钢空心型材接头处的焊接连接
如果计算中未涵盖圆周上的非线性应力分布,则根据EN 1993‐1‐8使用设计公式计算空心截面接头的承载能力时,假设为全强度焊接连接。连接件具有足够的延展性,确保了每个接头内的塑性再分布能力。在由高强度钢制成的空心截面结构的情况下,随着母材屈服强度的增加,满足全强度焊缝的要求变得更加困难。

期刊介绍: Steel Construction publishes peerreviewed papers covering the entire field of steel construction research. In the interests of "construction without depletion", it skilfully combines steel with other forms of construction employing concrete, glass, cables and membranes to form integrated steelwork systems. Since 2010 Steel Construction is the official journal for ECCS- European Convention for Constructional Steelwork members. You will find more information about membership on the ECCS homepage. Topics include: -Design and construction of structures -Methods of analysis and calculation -Experimental and theoretical research projects and results -Composite construction -Steel buildings and bridges -Cable and membrane structures -Structural glazing -Masts and towers -Vessels, cranes and hydraulic engineering structures -Fire protection -Lightweight structures
