Steel-supported tech revolutionises building damping.steel structure

Welding expert Duane Miller wrote an excellent pair of articles for the February and March 2024 issues of STRUCTURE Magazine. The articles described 10 conditions where welds can experience uneven loading. These conditions can be problematic if not avoided or given special attention in design. The common assumption that applied loads cause uniform stresses in a weld does not apply for these conditions. However, what if you are using a design approach that never makes such an assumption? Connection design by inelastic analysis, for example using the component-based finite element method (CBFEM) such as implemented in IDEA StatiCa Connection, makes no broad assumptions about the distribution of stress in welds, or any other components. Stresses arise naturally in the analysis based on the stiffness of the various components of the connection. This article walks through each of Miller’s 10 conditions to identify what special attention they require when designing by inelastic analysis.

The main topic of discussion in the European long steel market this week has been the new country-specific quotas (CSQs) of the EU, which market participants had been eagerly awaiting.

Modular steel construction could transform the construction industry and go some way to helping the sector cut its carbon footprint.

Com­ing to the first quarter of 2026, the world H beam steel Market is also facing a turning point. Driven by rapid infrastructure building in U.S., Southeast Asia and Latin America, as well as energy transition projects, the need for H-beams (particularly high-strength types like ASTM A572 Grade 50 H Beam and A992 H Beam) is beginning to recover strongly. However, trade-protecting policies, fluctuation of raw material prices and green and low-carbon transition are reforming the global price system altogether.
