Connection behaviour and the robustness of steel-framed structures in fire [PDF]

, 2018
The full-scale fire tests at Cardington in the 1990s, and the collapse of at least one of the WTC buildings in 2001, illustrated that connections are potentially the most vulnerable parts of a structure in fire.

Steel Beam-to-Column Friction Joint under a Column Loss Scenario

Buildings
FREEDAM joints have been recently seismically prequalified for applications in European seismically prone countries. Despite their excellent seismic response, FREEDAM joints are not purposely conceived for exceptional loading conditions, such as in the ...

Theoretical assessment of progressive collapse capacity of reinforced concrete structures [PDF]

, 2017
The progressive collapse behaviour of reinforced concrete (RC) structures requires consideration of material and geometric non-linearity, concrete crushing and rebar fracture.

Robustness assessment of reinforced concrete structures for different failure scenarios

Structural Concrete, Volume 27, Issue 1, Page 279-313, February 2026.
Abstract This study describes the robustness assessment of 3D reinforced concrete structures analyzing the response of the 2D frames in different design configurations and failure scenarios. The structures are characterized by both frames with wide beams and seismic‐resistant frames with deep beams.

A Simplified Theoretical Model for Progressive Collapse Resistance of Steel Girders: Focusing on Load–Displacement Behavior Under Three Concentrated Loads

Buildings
Progressive collapse is characterized by disproportionate structural failure triggered by localized damage, such as column loss under extreme loading conditions.

A Design of an Axisymmetric Roof With a Horizontal Rotation Axis

Studies in Applied Mathematics, Volume 156, Issue 1, January 2026.
ABSTRACT This research proposes a novel roof design whose shape follows the mathematical model of an ideal hanging surface. The resulting roof is a surface of revolution, but its rotation axis is horizontal, which challenges conventional intuition because the axis is perpendicular to the direction of gravity.

An analytical and numerical prediction for ductility demand on steel beam-to-column connections in fire [PDF]

, 2016
In this paper a simplified analytical method to assess the ductility demand on connections according to fire resistance requirements is developed on the basis of fundamental structural mechanics principles.

The Catenary Line: Numerical Aspects and Solutions for Special Boundary Conditions

Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 3, September 2025.
ABSTRACT The rope curve, or catenary, is a mechanical problem that has been solved since the 17th century. The hyperbolic cosine curve as its solution is the subject of many mechanics textbooks. Nevertheless, it is worth taking another look at the catenary because technical applications, for example, cable cars or suspension cables, have boundary ...

Numerical Investigation of Progressive Collapse Resistance in Fully Bonded Prestressed Precast Concrete Spatial Frame Systems with and Without Precast Slabs

Buildings
Preventing progressive collapse induced by accidental events poses a critical challenge in the design and construction of resilient structures. While substantial progress has been made in planar structures, the progressive collapse mechanisms of precast ...
